How to Write an Abstract | Steps & Examples

Published on February 28, 2019 by Shona McCombes . Revised on July 18, 2023 by Eoghan Ryan.

An abstract is a short summary of a longer work (such as a thesis ,  dissertation or research paper ). The abstract concisely reports the aims and outcomes of your research, so that readers know exactly what your paper is about.

Although the structure may vary slightly depending on your discipline, your abstract should describe the purpose of your work, the methods you’ve used, and the conclusions you’ve drawn.

One common way to structure your abstract is to use the IMRaD structure. This stands for:

• Introduction

Abstracts are usually around 100–300 words, but there’s often a strict word limit, so make sure to check the relevant requirements.

In a dissertation or thesis , include the abstract on a separate page, after the title page and acknowledgements but before the table of contents .

Hover over the different parts of the abstract to see how it is constructed.

This paper examines the role of silent movies as a mode of shared experience in the US during the early twentieth century. At this time, high immigration rates resulted in a significant percentage of non-English-speaking citizens. These immigrants faced numerous economic and social obstacles, including exclusion from public entertainment and modes of discourse (newspapers, theater, radio).

Incorporating evidence from reviews, personal correspondence, and diaries, this study demonstrates that silent films were an affordable and inclusive source of entertainment. It argues for the accessible economic and representational nature of early cinema. These concerns are particularly evident in the low price of admission and in the democratic nature of the actors’ exaggerated gestures, which allowed the plots and action to be easily grasped by a diverse audience despite language barriers.

Keywords: silent movies, immigration, public discourse, entertainment, early cinema, language barriers.

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

You will almost always have to include an abstract when:

• Completing a thesis or dissertation
• Submitting a research paper to an academic journal
• Writing a book or research proposal
• Applying for research grants

It’s easiest to write your abstract last, right before the proofreading stage, because it’s a summary of the work you’ve already done. Your abstract should:

• Be a self-contained text, not an excerpt from your paper
• Be fully understandable on its own
• Reflect the structure of your larger work

Start by clearly defining the purpose of your research. What practical or theoretical problem does the research respond to, or what research question did you aim to answer?

You can include some brief context on the social or academic relevance of your dissertation topic , but don’t go into detailed background information. If your abstract uses specialized terms that would be unfamiliar to the average academic reader or that have various different meanings, give a concise definition.

After identifying the problem, state the objective of your research. Use verbs like “investigate,” “test,” “analyze,” or “evaluate” to describe exactly what you set out to do.

This part of the abstract can be written in the present or past simple tense  but should never refer to the future, as the research is already complete.

• This study will investigate the relationship between coffee consumption and productivity.
• This study investigates the relationship between coffee consumption and productivity.

Next, indicate the research methods that you used to answer your question. This part should be a straightforward description of what you did in one or two sentences. It is usually written in the past simple tense, as it refers to completed actions.

• Structured interviews will be conducted with 25 participants.
• Structured interviews were conducted with 25 participants.

Don’t evaluate validity or obstacles here — the goal is not to give an account of the methodology’s strengths and weaknesses, but to give the reader a quick insight into the overall approach and procedures you used.

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

Next, summarize the main research results . This part of the abstract can be in the present or past simple tense.

• Our analysis has shown a strong correlation between coffee consumption and productivity.
• Our analysis shows a strong correlation between coffee consumption and productivity.
• Our analysis showed a strong correlation between coffee consumption and productivity.

Depending on how long and complex your research is, you may not be able to include all results here. Try to highlight only the most important findings that will allow the reader to understand your conclusions.

Finally, you should discuss the main conclusions of your research : what is your answer to the problem or question? The reader should finish with a clear understanding of the central point that your research has proved or argued. Conclusions are usually written in the present simple tense.

• We concluded that coffee consumption increases productivity.
• We conclude that coffee consumption increases productivity.

If there are important limitations to your research (for example, related to your sample size or methods), you should mention them briefly in the abstract. This allows the reader to accurately assess the credibility and generalizability of your research.

If your aim was to solve a practical problem, your discussion might include recommendations for implementation. If relevant, you can briefly make suggestions for further research.

If your paper will be published, you might have to add a list of keywords at the end of the abstract. These keywords should reference the most important elements of the research to help potential readers find your paper during their own literature searches.

Be aware that some publication manuals, such as APA Style , have specific formatting requirements for these keywords.

It can be a real challenge to condense your whole work into just a couple of hundred words, but the abstract will be the first (and sometimes only) part that people read, so it’s important to get it right. These strategies can help you get started.

Read other abstracts

The best way to learn the conventions of writing an abstract in your discipline is to read other people’s. You probably already read lots of journal article abstracts while conducting your literature review —try using them as a framework for structure and style.

You can also find lots of dissertation abstract examples in thesis and dissertation databases .

Reverse outline

Not all abstracts will contain precisely the same elements. For longer works, you can write your abstract through a process of reverse outlining.

For each chapter or section, list keywords and draft one to two sentences that summarize the central point or argument. This will give you a framework of your abstract’s structure. Next, revise the sentences to make connections and show how the argument develops.

Write clearly and concisely

A good abstract is short but impactful, so make sure every word counts. Each sentence should clearly communicate one main point.

To keep your abstract or summary short and clear:

• Avoid passive sentences: Passive constructions are often unnecessarily long. You can easily make them shorter and clearer by using the active voice.
• Avoid long sentences: Substitute longer expressions for concise expressions or single words (e.g., “In order to” for “To”).
• Avoid obscure jargon: The abstract should be understandable to readers who are not familiar with your topic.
• Avoid repetition and filler words: Replace nouns with pronouns when possible and eliminate unnecessary words.
• Avoid detailed descriptions: An abstract is not expected to provide detailed definitions, background information, or discussions of other scholars’ work. Instead, include this information in the body of your thesis or paper.

If you’re struggling to edit down to the required length, you can get help from expert editors with Scribbr’s professional proofreading services or use the paraphrasing tool .

Check your formatting

If you are writing a thesis or dissertation or submitting to a journal, there are often specific formatting requirements for the abstract—make sure to check the guidelines and format your work correctly. For APA research papers you can follow the APA abstract format .

Checklist: Abstract

The word count is within the required length, or a maximum of one page.

The abstract appears after the title page and acknowledgements and before the table of contents .

I have clearly stated my research problem and objectives.

I have briefly described my methodology .

I have summarized the most important results .

I have stated my main conclusions .

An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:

• To help potential readers determine the relevance of your paper for their own research.
• To communicate your key findings to those who don’t have time to read the whole paper.

Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarizes the contents of your paper.

An abstract for a thesis or dissertation is usually around 200–300 words. There’s often a strict word limit, so make sure to check your university’s requirements.

The abstract is the very last thing you write. You should only write it after your research is complete, so that you can accurately summarize the entirety of your thesis , dissertation or research paper .

Avoid citing sources in your abstract . There are two reasons for this:

• The abstract should focus on your original research, not on the work of others.
• The abstract should be self-contained and fully understandable without reference to other sources.

There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.

The abstract appears on its own page in the thesis or dissertation , after the title page and acknowledgements but before the table of contents .

Writing an Abstract for Your Research Paper

Definition and Purpose of Abstracts

An abstract is a short summary of your (published or unpublished) research paper, usually about a paragraph (c. 6-7 sentences, 150-250 words) long. A well-written abstract serves multiple purposes:

• an abstract lets readers get the gist or essence of your paper or article quickly, in order to decide whether to read the full paper;
• an abstract prepares readers to follow the detailed information, analyses, and arguments in your full paper;
• and, later, an abstract helps readers remember key points from your paper.

It’s also worth remembering that search engines and bibliographic databases use abstracts, as well as the title, to identify key terms for indexing your published paper. So what you include in your abstract and in your title are crucial for helping other researchers find your paper or article.

If you are writing an abstract for a course paper, your professor may give you specific guidelines for what to include and how to organize your abstract. Similarly, academic journals often have specific requirements for abstracts. So in addition to following the advice on this page, you should be sure to look for and follow any guidelines from the course or journal you’re writing for.

The Contents of an Abstract

Abstracts contain most of the following kinds of information in brief form. The body of your paper will, of course, develop and explain these ideas much more fully. As you will see in the samples below, the proportion of your abstract that you devote to each kind of information—and the sequence of that information—will vary, depending on the nature and genre of the paper that you are summarizing in your abstract. And in some cases, some of this information is implied, rather than stated explicitly. The Publication Manual of the American Psychological Association , which is widely used in the social sciences, gives specific guidelines for what to include in the abstract for different kinds of papers—for empirical studies, literature reviews or meta-analyses, theoretical papers, methodological papers, and case studies.

Here are the typical kinds of information found in most abstracts:

• the context or background information for your research; the general topic under study; the specific topic of your research
• the central questions or statement of the problem your research addresses
• what’s already known about this question, what previous research has done or shown
• the main reason(s) , the exigency, the rationale , the goals for your research—Why is it important to address these questions? Are you, for example, examining a new topic? Why is that topic worth examining? Are you filling a gap in previous research? Applying new methods to take a fresh look at existing ideas or data? Resolving a dispute within the literature in your field? . . .
• your research and/or analytical methods
• your main findings , results , or arguments
• the significance or implications of your findings or arguments.

Your abstract should be intelligible on its own, without a reader’s having to read your entire paper. And in an abstract, you usually do not cite references—most of your abstract will describe what you have studied in your research and what you have found and what you argue in your paper. In the body of your paper, you will cite the specific literature that informs your research.

When to Write Your Abstract

Although you might be tempted to write your abstract first because it will appear as the very first part of your paper, it’s a good idea to wait to write your abstract until after you’ve drafted your full paper, so that you know what you’re summarizing.

What follows are some sample abstracts in published papers or articles, all written by faculty at UW-Madison who come from a variety of disciplines. We have annotated these samples to help you see the work that these authors are doing within their abstracts.

Choosing Verb Tenses within Your Abstract

The social science sample (Sample 1) below uses the present tense to describe general facts and interpretations that have been and are currently true, including the prevailing explanation for the social phenomenon under study. That abstract also uses the present tense to describe the methods, the findings, the arguments, and the implications of the findings from their new research study. The authors use the past tense to describe previous research.

The humanities sample (Sample 2) below uses the past tense to describe completed events in the past (the texts created in the pulp fiction industry in the 1970s and 80s) and uses the present tense to describe what is happening in those texts, to explain the significance or meaning of those texts, and to describe the arguments presented in the article.

The science samples (Samples 3 and 4) below use the past tense to describe what previous research studies have done and the research the authors have conducted, the methods they have followed, and what they have found. In their rationale or justification for their research (what remains to be done), they use the present tense. They also use the present tense to introduce their study (in Sample 3, “Here we report . . .”) and to explain the significance of their study (In Sample 3, This reprogramming . . . “provides a scalable cell source for. . .”).

Sample Abstract 4, a Structured Abstract

Reporting results about the effectiveness of antibiotic therapy in managing acute bacterial sinusitis, from a rigorously controlled study

Note: This journal requires authors to organize their abstract into four specific sections, with strict word limits. Because the headings for this structured abstract are self-explanatory, we have chosen not to add annotations to this sample abstract.

Wald, Ellen R., David Nash, and Jens Eickhoff. “Effectiveness of Amoxicillin/Clavulanate Potassium in the Treatment of Acute Bacterial Sinusitis in Children.” Pediatrics , vol. 124, no. 1, 2009, pp. 9-15.

“OBJECTIVE: The role of antibiotic therapy in managing acute bacterial sinusitis (ABS) in children is controversial. The purpose of this study was to determine the effectiveness of high-dose amoxicillin/potassium clavulanate in the treatment of children diagnosed with ABS.

METHODS : This was a randomized, double-blind, placebo-controlled study. Children 1 to 10 years of age with a clinical presentation compatible with ABS were eligible for participation. Patients were stratified according to age (<6 or ≥6 years) and clinical severity and randomly assigned to receive either amoxicillin (90 mg/kg) with potassium clavulanate (6.4 mg/kg) or placebo. A symptom survey was performed on days 0, 1, 2, 3, 5, 7, 10, 20, and 30. Patients were examined on day 14. Children’s conditions were rated as cured, improved, or failed according to scoring rules.

RESULTS: Two thousand one hundred thirty-five children with respiratory complaints were screened for enrollment; 139 (6.5%) had ABS. Fifty-eight patients were enrolled, and 56 were randomly assigned. The mean age was 6630 months. Fifty (89%) patients presented with persistent symptoms, and 6 (11%) presented with nonpersistent symptoms. In 24 (43%) children, the illness was classified as mild, whereas in the remaining 32 (57%) children it was severe. Of the 28 children who received the antibiotic, 14 (50%) were cured, 4 (14%) were improved, 4(14%) experienced treatment failure, and 6 (21%) withdrew. Of the 28children who received placebo, 4 (14%) were cured, 5 (18%) improved, and 19 (68%) experienced treatment failure. Children receiving the antibiotic were more likely to be cured (50% vs 14%) and less likely to have treatment failure (14% vs 68%) than children receiving the placebo.

CONCLUSIONS : ABS is a common complication of viral upper respiratory infections. Amoxicillin/potassium clavulanate results in significantly more cures and fewer failures than placebo, according to parental report of time to resolution.” (9)

• How to Write an Abstract for a Dissertation or Thesis
• Doing a PhD

What is a Thesis or Dissertation Abstract?

The Cambridge English Dictionary defines an abstract in academic writing as being “ a few sentences that give the main ideas in an article or a scientific paper ” and the Collins English Dictionary says “ an abstract of an article, document, or speech is a short piece of writing that gives the main points of it ”.

Whether you’re writing up your Master’s dissertation or PhD thesis, the abstract will be a key element of this document that you’ll want to make sure you give proper attention to.

What is the Purpose of an Abstract?

The aim of a thesis abstract is to give the reader a broad overview of what your research project was about and what you found that was novel, before he or she decides to read the entire thesis. The reality here though is that very few people will read the entire thesis, and not because they’re necessarily disinterested but because practically it’s too large a document for most people to have the time to read. The exception to this is your PhD examiner, however know that even they may not read the entire length of the document.

Some people may still skip to and read specific sections throughout your thesis such as the methodology, but the fact is that the abstract will be all that most read and will therefore be the section they base their opinions about your research on. In short, make sure you write a good, well-structured abstract.

How Long Should an Abstract Be?

If you’re a PhD student, having written your 100,000-word thesis, the abstract will be the 300 word summary included at the start of the thesis that succinctly explains the motivation for your study (i.e. why this research was needed), the main work you did (i.e. the focus of each chapter), what you found (the results) and concluding with how your research study contributed to new knowledge within your field.

Woodrow Wilson, the 28th President of the United States of America, once famously said:

The point here is that it’s easier to talk open-endedly about a subject that you know a lot about than it is to condense the key points into a 10-minute speech; the same applies for an abstract. Three hundred words is not a lot of words which makes it even more difficult to condense three (or more) years of research into a coherent, interesting story.

What Makes a Good PhD Thesis Abstract?

Whilst the abstract is one of the first sections in your PhD thesis, practically it’s probably the last aspect that you’ll ending up writing before sending the document to print. The reason being that you can’t write a summary about what you did, what you found and what it means until you’ve done the work.

A good abstract is one that can clearly explain to the reader in 300 words:

• What your research field actually is,
• What the gap in knowledge was in your field,
• The overarching aim and objectives of your PhD in response to these gaps,
• What methods you employed to achieve these,
• You key results and findings,
• How your work has added to further knowledge in your field of study.

Another way to think of this structure is:

• Introduction,
• Aims and objectives,
• Discussion,
• Conclusion.

Following this ‘formulaic’ approach to writing the abstract should hopefully make it a little easier to write but you can already see here that there’s a lot of information to convey in a very limited number of words.

How Do You Write a Good PhD Thesis Abstract?

The biggest challenge you’ll have is getting all the 6 points mentioned above across in your abstract within the limit of 300 words . Your particular university may give some leeway in going a few words over this but it’s good practice to keep within this; the art of succinctly getting your information across is an important skill for a researcher to have and one that you’ll be called on to use regularly as you write papers for peer review.

Keep It Concise

Every word in the abstract is important so make sure you focus on only the key elements of your research and the main outcomes and significance of your project that you want the reader to know about. You may have come across incidental findings during your research which could be interesting to discuss but this should not happen in the abstract as you simply don’t have enough words. Furthermore, make sure everything you talk about in your thesis is actually described in the main thesis.

Make a Unique Point Each Sentence

Keep the sentences short and to the point. Each sentence should give the reader new, useful information about your research so there’s no need to write out your project title again. Give yourself one or two sentences to introduce your subject area and set the context for your project. Then another sentence or two to explain the gap in the knowledge; there’s no need or expectation for you to include references in the abstract.

Explain Your Research

Some people prefer to write their overarching aim whilst others set out their research questions as they correspond to the structure of their thesis chapters; the approach you use is up to you, as long as the reader can understand what your dissertation or thesis had set out to achieve. Knowing this will help the reader better understand if your results help to answer the research questions or if further work is needed.

Keep It Factual

Keep the content of the abstract factual; that is to say that you should avoid bringing too much or any opinion into it, which inevitably can make the writing seem vague in the points you’re trying to get across and even lacking in structure.

Write, Edit and Then Rewrite

Spend suitable time editing your text, and if necessary, completely re-writing it. Show the abstract to others and ask them to explain what they understand about your research – are they able to explain back to you each of the 6 structure points, including why your project was needed, the research questions and results, and the impact it had on your research field? It’s important that you’re able to convey what new knowledge you contributed to your field but be mindful when writing your abstract that you don’t inadvertently overstate the conclusions, impact and significance of your work.

Thesis and Dissertation Abstract Examples

Perhaps the best way to understand how to write a thesis abstract is to look at examples of what makes a good and bad abstract.

Example of A Bad Abstract

Let’s start with an example of a bad thesis abstract:

In this project on “The Analysis of the Structural Integrity of 3D Printed Polymers for use in Aircraft”, my research looked at how 3D printing of materials can help the aviation industry in the manufacture of planes. Plane parts can be made at a lower cost using 3D printing and made lighter than traditional components. This project investigated the structural integrity of EBM manufactured components, which could revolutionise the aviation industry.

What Makes This a Bad Abstract

Hopefully you’ll have spotted some of the reasons this would be considered a poor abstract, not least because the author used up valuable words by repeating the lengthy title of the project in the abstract.

Working through our checklist of the 6 key points you want to convey to the reader:

• There has been an attempt to introduce the research area , albeit half-way through the abstract but it’s not clear if this is a materials science project about 3D printing or is it about aircraft design.
• There’s no explanation about where the gap in the knowledge is that this project attempted to address.
• We can see that this project was focussed on the topic of structural integrity of materials in aircraft but the actual research aims or objectives haven’t been defined.
• There’s no mention at all of what the author actually did to investigate structural integrity. For example was this an experimental study involving real aircraft, or something in the lab, computer simulations etc.
• The author also doesn’t tell us a single result of his research, let alone the key findings !
• There’s a bold claim in the last sentence of the abstract that this project could revolutionise the aviation industry, and this may well be the case, but based on the abstract alone there is no evidence to support this as it’s not even clear what the author did .

This is an extreme example but is a good way to illustrate just how unhelpful a poorly written abstract can be. At only 71 words long, it definitely hasn’t maximised the amount of information that could be presented and the what they have presented has lacked clarity and structure.

A final point to note is the use of the EBM acronym, which stands for Electron Beam Melting in the context of 3D printing; this is a niche acronym for the author to assume that the reader would know the meaning of. It’s best to avoid acronyms in your abstract all together even if it’s something that you might expect most people to know about, unless you specifically define the meaning first.

Example of A Good Abstract

Having seen an example of a bad thesis abstract, now lets look at an example of a good PhD thesis abstract written about the same (fictional) project:

Additive manufacturing (AM) of titanium alloys has the potential to enable cheaper and lighter components to be produced with customised designs for use in aircraft engines. Whilst the proof-of-concept of these have been promising, the structural integrity of AM engine parts in response to full thrust and temperature variations is not clear.

The primary aim of this project was to determine the fracture modes and mechanisms of AM components designed for use in Boeing 747 engines. To achieve this an explicit finite element (FE) model was developed to simulate the environment and parameters that the engine is exposed to during flight. The FE model was validated using experimental data replicating the environmental parameters in a laboratory setting using ten AM engine components provided by the industry sponsor. The validated FE model was then used to investigate the extent of crack initiation and propagation as the environment parameters were adjusted.

This project was the first to investigate fracture patterns in AM titanium components used in aircraft engines; the key finding was that the presence of cavities within the structures due to errors in the printing process, significantly increased the risk of fracture. Secondly, the simulations showed that cracks formed within AM parts were more likely to worsen and lead to component failure at subzero temperatures when compared to conventionally manufactured parts. This has demonstrated an important safety concern which needs to be addressed before AM parts can be used in commercial aircraft.

What Makes This a Good Abstract

Having read this ‘good abstract’ you should have a much better understand about what the subject area is about, where the gap in the knowledge was, the aim of the project, the methods that were used, key results and finally the significance of these results. To break these points down further, from this good abstract we now know that:

• The research area is around additive manufacturing (i.e. 3D printing) of materials for use in aircraft.
• The gap in knowledge was how these materials will behave structural when used in aircraft engines.
• The aim was specifically to investigate how the components can fracture.
• The methods used to investigate this were a combination of computational and lab based experimental modelling.
• The key findings were the increased risk of fracture of these components due to the way they are manufactured.
• The significance of these findings were that it showed a potential risk of component failure that could comprise the safety of passengers and crew on the aircraft.

The abstract text has a much clearer flow through these different points in how it’s written and has made much better use of the available word count. Acronyms have even been used twice in this good abstract but they were clearly defined the first time they were introduced in the text so that there was no confusion about their meaning.

The abstract you write for your dissertation or thesis should succinctly explain to the reader why the work of your research was needed, what you did, what you found and what it means. Most people that come across your thesis, including any future employers, are likely to read only your abstract. Even just for this reason alone, it’s so important that you write the best abstract you can; this will not only convey your research effectively but also put you in the best light possible as a researcher.

What is an abstract in a paper, how long should an abstract be, 5 steps for writing an abstract, examples of an abstract, how prowritingaid can help you write an abstract.

If you are writing a scientific research paper or a book proposal, you need to know how to write an abstract, which summarizes the contents of the paper or book.

When researchers are looking for peer-reviewed papers to use in their studies, the first place they will check is the abstract to see if it applies to their work. Therefore, your abstract is one of the most important parts of your entire paper.

In this article, we’ll explain what an abstract is, what it should include, and how to write one.

An abstract is a concise summary of the details within a report. Some abstracts give more details than others, but the main things you’ll be talking about are why you conducted the research, what you did, and what the results show.

When a reader is deciding whether to read your paper completely, they will first look at the abstract. You need to be concise in your abstract and give the reader the most important information so they can determine if they want to read the whole paper.

Remember that an abstract is the last thing you’ll want to write for the research paper because it directly references parts of the report. If you haven’t written the report, you won’t know what to include in your abstract.

If you are writing a paper for a journal or an assignment, the publication or academic institution might have specific formatting rules for how long your abstract should be. However, if they don’t, most abstracts are between 150 and 300 words long.

A short word count means your writing has to be precise and without filler words or phrases. Once you’ve written a first draft, you can always use an editing tool, such as ProWritingAid, to identify areas where you can reduce words and increase readability.

If your abstract is over the word limit, and you’ve edited it but still can’t figure out how to reduce it further, your abstract might include some things that aren’t needed. Here’s a list of three elements you can remove from your abstract:

Discussion : You don’t need to go into detail about the findings of your research because your reader will find your discussion within the paper.

Definition of terms : Your readers are interested the field you are writing about, so they are likely to understand the terms you are using. If not, they can always look them up. Your readers do not expect you to give a definition of terms in your abstract.

References and citations : You can mention there have been studies that support or have inspired your research, but you do not need to give details as the reader will find them in your bibliography.

Good writing = better grades

ProWritingAid will help you improve the style, strength, and clarity of all your assignments.

If you’ve never written an abstract before, and you’re wondering how to write an abstract, we’ve got some steps for you to follow. It’s best to start with planning your abstract, so we’ve outlined the details you need to include in your plan before you write.

Remember to consider your audience when you’re planning and writing your abstract. They are likely to skim read your abstract, so you want to be sure your abstract delivers all the information they’re expecting to see at key points.

1. What Should an Abstract Include?

Abstracts have a lot of information to cover in a short number of words, so it’s important to know what to include. There are three elements that need to be present in your abstract:

Your context is the background for where your research sits within your field of study. You should briefly mention any previous scientific papers or experiments that have led to your hypothesis and how research develops in those studies.

Your hypothesis is your prediction of what your study will show. As you are writing your abstract after you have conducted your research, you should still include your hypothesis in your abstract because it shows the motivation for your paper.

Throughout your abstract, you also need to include keywords and phrases that will help researchers to find your article in the databases they’re searching. Make sure the keywords are specific to your field of study and the subject you’re reporting on, otherwise your article might not reach the relevant audience.

2. Can You Use First Person in an Abstract?

You might think that first person is too informal for a research paper, but it’s not. Historically, writers of academic reports avoided writing in first person to uphold the formality standards of the time. However, first person is more accepted in research papers in modern times.

If you’re still unsure whether to write in first person for your abstract, refer to any style guide rules imposed by the journal you’re writing for or your teachers if you are writing an assignment.

3. Abstract Structure

Some scientific journals have strict rules on how to structure an abstract, so it’s best to check those first. If you don’t have any style rules to follow, try using the IMRaD structure, which stands for Introduction, Methodology, Results, and Discussion.

Following the IMRaD structure, start with an introduction. The amount of background information you should include depends on your specific research area. Adding a broad overview gives you less room to include other details. Remember to include your hypothesis in this section.

The next part of your abstract should cover your methodology. Try to include the following details if they apply to your study:

What type of research was conducted?

How were the test subjects sampled?

What were the sample sizes?

What was done to each group?

How long was the experiment?

How was data recorded and interpreted?

Following the methodology, include a sentence or two about the results, which is where your reader will determine if your research supports or contradicts their own investigations.

The results are also where most people will want to find out what your outcomes were, even if they are just mildly interested in your research area. You should be specific about all the details but as concise as possible.

The last few sentences are your conclusion. It needs to explain how your findings affect the context and whether your hypothesis was correct. Include the primary take-home message, additional findings of importance, and perspective. Also explain whether there is scope for further research into the subject of your report.

Your conclusion should be honest and give the reader the ultimate message that your research shows. Readers trust the conclusion, so make sure you’re not fabricating the results of your research. Some readers won’t read your entire paper, but this section will tell them if it’s worth them referencing it in their own study.

4. How to Start an Abstract

The first line of your abstract should give your reader the context of your report by providing background information. You can use this sentence to imply the motivation for your research.

You don’t need to use a hook phrase or device in your first sentence to grab the reader’s attention. Your reader will look to establish relevance quickly, so readability and clarity are more important than trying to persuade the reader to read on.

5. How to Format an Abstract

Most abstracts use the same formatting rules, which help the reader identify the abstract so they know where to look for it.

Here’s a list of formatting guidelines for writing an abstract:

Stick to one paragraph

Use block formatting with no indentation at the beginning

Put your abstract straight after the title and acknowledgements pages

Use present or past tense, not future tense

There are two primary types of abstract you could write for your paper—descriptive and informative.

An informative abstract is the most common, and they follow the structure mentioned previously. They are longer than descriptive abstracts because they cover more details.

Descriptive abstracts differ from informative abstracts, as they don’t include as much discussion or detail. The word count for a descriptive abstract is between 50 and 150 words.

Here is an example of an informative abstract:

A growing trend exists for authors to employ a more informal writing style that uses “we” in academic writing to acknowledge one’s stance and engagement. However, few studies have compared the ways in which the first-person pronoun “we” is used in the abstracts and conclusions of empirical papers. To address this lacuna in the literature, this study conducted a systematic corpus analysis of the use of “we” in the abstracts and conclusions of 400 articles collected from eight leading electrical and electronic (EE) engineering journals. The abstracts and conclusions were extracted to form two subcorpora, and an integrated framework was applied to analyze and seek to explain how we-clusters and we-collocations were employed. Results revealed whether authors’ use of first-person pronouns partially depends on a journal policy. The trend of using “we” showed that a yearly increase occurred in the frequency of “we” in EE journal papers, as well as the existence of three “we-use” types in the article conclusions and abstracts: exclusive, inclusive, and ambiguous. Other possible “we-use” alternatives such as “I” and other personal pronouns were used very rarely—if at all—in either section. These findings also suggest that the present tense was used more in article abstracts, but the present perfect tense was the most preferred tense in article conclusions. Both research and pedagogical implications are proffered and critically discussed.

Wang, S., Tseng, W.-T., & Johanson, R. (2021). To We or Not to We: Corpus-Based Research on First-Person Pronoun Use in Abstracts and Conclusions. SAGE Open, 11(2).

Here is an example of a descriptive abstract:

From the 1850s to the present, considerable criminological attention has focused on the development of theoretically-significant systems for classifying crime. This article reviews and attempts to evaluate a number of these efforts, and we conclude that further work on this basic task is needed. The latter part of the article explicates a conceptual foundation for a crime pattern classification system, and offers a preliminary taxonomy of crime.

Farr, K. A., & Gibbons, D. C. (1990). Observations on the Development of Crime Categories. International Journal of Offender Therapy and Comparative Criminology, 34(3), 223–237.

If you want to ensure your abstract is grammatically correct and easy to read, you can use ProWritingAid to edit it. The software integrates with Microsoft Word, Google Docs, and most web browsers, so you can make the most of it wherever you’re writing your paper.

Before you edit with ProWritingAid, make sure the suggestions you are seeing are relevant for your document by changing the document type to “Abstract” within the Academic writing style section.

You can use the Readability report to check your abstract for places to improve the clarity of your writing. Some suggestions might show you where to remove words, which is great if you’re over your word count.

We hope the five steps and examples we’ve provided help you write a great abstract for your research paper.

Writing an abstract - a six point checklist (with samples)

Posted in: abstract , dissertations

The abstract is a vital part of any research paper. It is the shop front for your work, and the first stop for your reader. It should provide a clear and succinct summary of your study, and encourage your readers to read more. An effective abstract, therefore should answer the following questions:

• Why did you do this study or project?
• What did you do and how?
• What did you find?
• What do your findings mean?

So here's our run down of the key elements of a well-written abstract.

• Size - A succinct and well written abstract should be between approximately 100- 250 words.
• Background - An effective abstract usually includes some scene-setting information which might include what is already known about the subject, related to the paper in question (a few short sentences).
• Purpose  - The abstract should also set out the purpose of your research, in other words, what is not known about the subject and hence what the study intended to examine (or what the paper seeks to present).
• Methods - The methods section should contain enough information to enable the reader to understand what was done, and how. It should include brief details of the research design, sample size, duration of study, and so on.
• Results - The results section is the most important part of the abstract. This is because readers who skim an abstract do so to learn about the findings of the study. The results section should therefore contain as much detail about the findings as the journal word count permits.
• Conclusion - This section should contain the most important take-home message of the study, expressed in a few precisely worded sentences. Usually, the finding highlighted here relates to the primary outcomes of the study. However, other important or unexpected findings should also be mentioned. It is also customary, but not essential, to express an opinion about the theoretical or practical implications of the findings, or the importance of their findings for the field. Thus, the conclusions may contain three elements:
• The primary take-home message.
• Any additional findings of importance.
• Implications for future studies.

Example Abstract 2: Engineering Development and validation of a three-dimensional finite element model of the pelvic bone.

Abstract from: Dalstra, M., Huiskes, R. and Van Erning, L., 1995. Development and validation of a three-dimensional finite element model of the pelvic bone. Journal of biomechanical engineering, 117(3), pp.272-278.

And finally...  A word on abstract types and styles

Abstract types can differ according to subject discipline. You need to determine therefore which type of abstract you should include with your paper. Here are two of the most common types with examples.

Informative Abstract

The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the researcher presents and explains all the main arguments and the important results and evidence in the paper. An informative abstract includes the information that can be found in a descriptive abstract [purpose, methods, scope] but it also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is usually no more than 300 words in length.

Descriptive Abstract A descriptive abstract indicates the type of information found in the work. It makes no judgements about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract only describes the work being summarised. Some researchers consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short, 100 words or less.

Abstract Writing: A Step-by-Step Guide With Tips & Examples

Table of Contents

Introduction

Abstracts of research papers have always played an essential role in describing your research concisely and clearly to researchers and editors of journals, enticing them to continue reading. However, with the widespread availability of scientific databases, the need to write a convincing abstract is more crucial now than during the time of paper-bound manuscripts.

Abstracts serve to "sell" your research and can be compared with your "executive outline" of a resume or, rather, a formal summary of the critical aspects of your work. Also, it can be the "gist" of your study. Since most educational research is done online, it's a sign that you have a shorter time for impressing your readers, and have more competition from other abstracts that are available to be read.

The APCI (Academic Publishing and Conferences International) articulates 12 issues or points considered during the final approval process for conferences & journals and emphasises the importance of writing an abstract that checks all these boxes (12 points). Since it's the only opportunity you have to captivate your readers, you must invest time and effort in creating an abstract that accurately reflects the critical points of your research.

With that in mind, let’s head over to understand and discover the core concept and guidelines to create a substantial abstract. Also, learn how to organise the ideas or plots into an effective abstract that will be awe-inspiring to the readers you want to reach.

What is Abstract? Definition and Overview

The word "Abstract' is derived from Latin abstractus meaning "drawn off." This etymological meaning also applies to art movements as well as music, like abstract expressionism. In this context, it refers to the revealing of the artist's intention.

Based on this, you can determine the meaning of an abstract: A condensed research summary. It must be self-contained and independent of the body of the research. However, it should outline the subject, the strategies used to study the problem, and the methods implemented to attain the outcomes. The specific elements of the study differ based on the area of study; however, together, it must be a succinct summary of the entire research paper.

Abstracts are typically written at the end of the paper, even though it serves as a prologue. In general, the abstract must be in a position to:

• Describe the paper.
• Identify the problem or the issue at hand.
• Explain to the reader the research process, the results you came up with, and what conclusion you've reached using these results.
• Include keywords to guide your strategy and the content.

Furthermore, the abstract you submit should not reflect upon any of  the following elements:

• Examine, analyse or defend the paper or your opinion.
• What you want to study, achieve or discover.
• Be redundant or irrelevant.

After reading an abstract, your audience should understand the reason - what the research was about in the first place, what the study has revealed and how it can be utilised or can be used to benefit others. You can understand the importance of abstract by knowing the fact that the abstract is the most frequently read portion of any research paper. In simpler terms, it should contain all the main points of the research paper.

What is the Purpose of an Abstract?

Abstracts are typically an essential requirement for research papers; however, it's not an obligation to preserve traditional reasons without any purpose. Abstracts allow readers to scan the text to determine whether it is relevant to their research or studies. The abstract allows other researchers to decide if your research paper can provide them with some additional information. A good abstract paves the interest of the audience to pore through your entire paper to find the content or context they're searching for.

Abstract writing is essential for indexing, as well. The Digital Repository of academic papers makes use of abstracts to index the entire content of academic research papers. Like meta descriptions in the regular Google outcomes, abstracts must include keywords that help researchers locate what they seek.

Types of Abstract

Informative and Descriptive are two kinds of abstracts often used in scientific writing.

A descriptive abstract gives readers an outline of the author's main points in their study. The reader can determine if they want to stick to the research work, based on their interest in the topic. An abstract that is descriptive is similar to the contents table of books, however, the format of an abstract depicts complete sentences encapsulated in one paragraph. It is unfortunate that the abstract can't be used as a substitute for reading a piece of writing because it's just an overview, which omits readers from getting an entire view. Also, it cannot be a way to fill in the gaps the reader may have after reading this kind of abstract since it does not contain crucial information needed to evaluate the article.

To conclude, a descriptive abstract is:

• A simple summary of the task, just summarises the work, but some researchers think it is much more of an outline
• Typically, the length is approximately 100 words. It is too short when compared to an informative abstract.
• A brief explanation but doesn't provide the reader with the complete information they need;
• An overview that omits conclusions and results

An informative abstract is a comprehensive outline of the research. There are times when people rely on the abstract as an information source. And the reason is why it is crucial to provide entire data of particular research. A well-written, informative abstract could be a good substitute for the remainder of the paper on its own.

A well-written abstract typically follows a particular style. The author begins by providing the identifying information, backed by citations and other identifiers of the papers. Then, the major elements are summarised to make the reader aware of the study. It is followed by the methodology and all-important findings from the study. The conclusion then presents study results and ends the abstract with a comprehensive summary.

In a nutshell, an informative abstract:

• Has a length that can vary, based on the subject, but is not longer than 300 words.
• Contains all the content-like methods and intentions
• Offers evidence and possible recommendations.

Informative Abstracts are more frequent than descriptive abstracts because of their extensive content and linkage to the topic specifically. You should select different types of abstracts to papers based on their length: informative abstracts for extended and more complex abstracts and descriptive ones for simpler and shorter research papers.

What are the Characteristics of a Good Abstract?

• A good abstract clearly defines the goals and purposes of the study.
• It should clearly describe the research methodology with a primary focus on data gathering, processing, and subsequent analysis.
• A good abstract should provide specific research findings.
• It presents the principal conclusions of the systematic study.
• It should be concise, clear, and relevant to the field of study.
• A well-designed abstract should be unifying and coherent.
• It is easy to grasp and free of technical jargon.
• It is written impartially and objectively.

What are the various sections of an ideal Abstract?

By now, you must have gained some concrete idea of the essential elements that your abstract needs to convey . Accordingly, the information is broken down into six key sections of the abstract, which include:

An Introduction or Background

Research methodology, objectives and goals, limitations.

Let's go over them in detail.

The introduction, also known as background, is the most concise part of your abstract. Ideally, it comprises a couple of sentences. Some researchers only write one sentence to introduce their abstract. The idea behind this is to guide readers through the key factors that led to your study.

It's understandable that this information might seem difficult to explain in a couple of sentences. For example, think about the following two questions like the background of your study:

• What is currently available about the subject with respect to the paper being discussed?
• What isn't understood about this issue? (This is the subject of your research)

While writing the abstract’s introduction, make sure that it is not lengthy. Because if it crosses the word limit, it may eat up the words meant to be used for providing other key information.

Research methodology is where you describe the theories and techniques you used in your research. It is recommended that you describe what you have done and the method you used to get your thorough investigation results. Certainly, it is the second-longest paragraph in the abstract.

In the research methodology section, it is essential to mention the kind of research you conducted; for instance, qualitative research or quantitative research (this will guide your research methodology too) . If you've conducted quantitative research, your abstract should contain information like the sample size, data collection method, sampling techniques, and duration of the study. Likewise, your abstract should reflect observational data, opinions, questionnaires (especially the non-numerical data) if you work on qualitative research.

The research objectives and goals speak about what you intend to accomplish with your research. The majority of research projects focus on the long-term effects of a project, and the goals focus on the immediate, short-term outcomes of the research. It is possible to summarise both in just multiple sentences.

In stating your objectives and goals, you give readers a picture of the scope of the study, its depth and the direction your research ultimately follows. Your readers can evaluate the results of your research against the goals and stated objectives to determine if you have achieved the goal of your research.

In the end, your readers are more attracted by the results you've obtained through your study. Therefore, you must take the time to explain each relevant result and explain how they impact your research. The results section exists as the longest in your abstract, and nothing should diminish its reach or quality.

One of the most important things you should adhere to is to spell out details and figures on the results of your research.

Instead of making a vague assertion such as, "We noticed that response rates varied greatly between respondents with high incomes and those with low incomes", Try these: "The response rate was higher for high-income respondents than those with lower incomes (59 30 percent vs. 30 percent in both cases; P<0.01)."

You're likely to encounter certain obstacles during your research. It could have been during data collection or even during conducting the sample . Whatever the issue, it's essential to inform your readers about them and their effects on the research.

Research limitations offer an opportunity to suggest further and deep research. If, for instance, you were forced to change for convenient sampling and snowball samples because of difficulties in reaching well-suited research participants, then you should mention this reason when you write your research abstract. In addition, a lack of prior studies on the subject could hinder your research.

Your conclusion should include the same number of sentences to wrap the abstract as the introduction. The majority of researchers offer an idea of the consequences of their research in this case.

Your conclusion should include three essential components:

• A significant take-home message.
• Corresponding important findings.
• The Interpretation.

Even though the conclusion of your abstract needs to be brief, it can have an enormous influence on the way that readers view your research. Therefore, make use of this section to reinforce the central message from your research. Be sure that your statements reflect the actual results and the methods you used to conduct your research.

Good Abstract Examples

Abstract example #1.

Children’s consumption behavior in response to food product placements in movies.

The abstract:

"Almost all research into the effects of brand placements on children has focused on the brand's attitudes or behavior intentions. Based on the significant differences between attitudes and behavioral intentions on one hand and actual behavior on the other hand, this study examines the impact of placements by brands on children's eating habits. Children aged 6-14 years old were shown an excerpt from the popular film Alvin and the Chipmunks and were shown places for the item Cheese Balls. Three different versions were developed with no placements, one with moderately frequent placements and the third with the highest frequency of placement. The results revealed that exposure to high-frequency places had a profound effect on snack consumption, however, there was no impact on consumer attitudes towards brands or products. The effects were not dependent on the age of the children. These findings are of major importance to researchers studying consumer behavior as well as nutrition experts as well as policy regulators."

Abstract Example #2

Social comparisons on social media: The impact of Facebook on young women’s body image concerns and mood. The abstract:

"The research conducted in this study investigated the effects of Facebook use on women's moods and body image if the effects are different from an internet-based fashion journal and if the appearance comparison tendencies moderate one or more of these effects. Participants who were female ( N = 112) were randomly allocated to spend 10 minutes exploring their Facebook account or a magazine's website or an appearance neutral control website prior to completing state assessments of body dissatisfaction, mood, and differences in appearance (weight-related and facial hair, face, and skin). Participants also completed a test of the tendency to compare appearances. The participants who used Facebook were reported to be more depressed than those who stayed on the control site. In addition, women who have the tendency to compare appearances reported more facial, hair and skin-related issues following Facebook exposure than when they were exposed to the control site. Due to its popularity it is imperative to conduct more research to understand the effect that Facebook affects the way people view themselves."

Abstract Example #3

The Relationship Between Cell Phone Use and Academic Performance in a Sample of U.S. College Students

"The cellphone is always present on campuses of colleges and is often utilised in situations in which learning takes place. The study examined the connection between the use of cell phones and the actual grades point average (GPA) after adjusting for predictors that are known to be a factor. In the end 536 students in the undergraduate program from 82 self-reported majors of an enormous, public institution were studied. Hierarchical analysis ( R 2 = .449) showed that use of mobile phones is significantly ( p < .001) and negative (b equal to -.164) connected to the actual college GPA, after taking into account factors such as demographics, self-efficacy in self-regulated learning, self-efficacy to improve academic performance, and the actual high school GPA that were all important predictors ( p < .05). Therefore, after adjusting for other known predictors increasing cell phone usage was associated with lower academic performance. While more research is required to determine the mechanisms behind these results, they suggest the need to educate teachers and students to the possible academic risks that are associated with high-frequency mobile phone usage."

Quick tips on writing a good abstract

There exists a common dilemma among early age researchers whether to write the abstract at first or last? However, it's recommended to compose your abstract when you've completed the research since you'll have all the information to give to your readers. You can, however, write a draft at the beginning of your research and add in any gaps later.

If you find abstract writing a herculean task, here are the few tips to help you with it:

1. Always develop a framework to support your abstract

Before writing, ensure you create a clear outline for your abstract. Divide it into sections and draw the primary and supporting elements in each one. You can include keywords and a few sentences that convey the essence of your message.

2. Review Other Abstracts

Abstracts are among the most frequently used research documents, and thousands of them were written in the past. Therefore, prior to writing yours, take a look at some examples from other abstracts. There are plenty of examples of abstracts for dissertations in the dissertation and thesis databases.

3. Avoid Jargon To the Maximum

When you write your abstract, focus on simplicity over formality. You should  write in simple language, and avoid excessive filler words or ambiguous sentences. Keep in mind that your abstract must be readable to those who aren't acquainted with your subject.

4. Focus on Your Research

It's a given fact that the abstract you write should be about your research and the findings you've made. It is not the right time to mention secondary and primary data sources unless it's absolutely required.

Conclusion: How to Structure an Interesting Abstract?

Abstracts are a short outline of your essay. However, it's among the most important, if not the most important. The process of writing an abstract is not straightforward. A few early-age researchers tend to begin by writing it, thinking they are doing it to "tease" the next step (the document itself). However, it is better to treat it as a spoiler.

The simple, concise style of the abstract lends itself to a well-written and well-investigated study. If your research paper doesn't provide definitive results, or the goal of your research is questioned, so will the abstract. Thus, only write your abstract after witnessing your findings and put your findings in the context of a larger scenario.

The process of writing an abstract can be daunting, but with these guidelines, you will succeed. The most efficient method of writing an excellent abstract is to centre the primary points of your abstract, including the research question and goals methods, as well as key results.

• How to Write an Abstract for a Dissertation

Written by Hannah Slack

Every PhD student will have to write an abstract. Whether it’s for a conference paper , journal article or your thesis , the abstract is an important part for many academic activities. Although only a single short paragraph, writing one effectively takes practice.

This page will take you through what a dissertation abstract is, why it’s so important and how to write one.

What is an academic abstract?

An academic abstract is a short and concise summary of research . It should cover the aim or research question of your work, your methodology, results and the wider implications of your conclusions. All this needs to be covered in around 200-300 words .

One of the common mistakes people make when writing abstracts is not understanding their purpose. An abstract is not for the author, it’s for the reader . To summarise your research, as the person who knows it best, may seem easy. But to be able to communicate the complexities and importance of your work to someone else, likely outside of your field, can be difficult.

When will I need to write an academic abstract?

There are many different places that you’ll find abstracts. Some of the most common ones include:

• Grant and funding applications
• Journal articles
• Conference applications
• Conference proceedings

This guide primarily focuses on the dissertation abstract, which is the most common form of this kind of text.

What’s the difference between an abstract and an introduction?

The main differences between a PhD dissertation abstract and an introduction are the purpose and the length. An abstract is a short, paragraph-sized summary of the whole thesis, covering context, your research and results. Whereas an introduction should be much longer and only cover the context of your work. An introduction is designed to explain the background of your work and so will take up at least an entire page.

Why are abstracts important?

Abstracts are important because they are a quick and easy way to communicate your work. In many ways, academic abstracts are a promotional tool and so should be considered carefully.

For your thesis, it’s the first thing your examiners will read, forming their expectations for the rest of the dissertation.

In journal articles, their purpose is to convince the reader that they should read your article. If you’re applying for a conference, the abstract gives the organiser a taster of your paper so they can decide whether it’s suitable.

Effectively, your abstract is the first impression someone gets of your research and so it’s important to put your best foot forward.

How to write a PhD abstract

How you write a dissertation abstract will largely depend on what it’s for. For a PhD dissertation or journal article, you should have already written up the research which the abstract will summarise. You should focus on making sure your summary is an honest representation of the larger written work. However, for a conference application it’s likely you won’t yet have written the paper. In this instance, the abstract might focus more on the broader themes you intend to comment on and your methodology.

Whatever the intended purpose, all abstracts should broadly follow the same structure. To help you, we’ve put together a template to make sure you include all the important points.

PhD abstract format

Because a lot of information needs to be packed into a short paragraph, an abstract is easier to write when you break it down into the key elements. For a first draft, spend a few minutes on each of the six steps, only writing down one or two sentences.

• Rationale – Ask yourself why you are researching the topic and what is the context for your work. Here you should communicate the purpose of your study within the wider field.
• Research question – Now you should specify what the exact goal of this piece of research is. What question are you providing the answer for?
• Evidence and methods – After discussing the broader purpose of your work you now need to let the reader know what you have actually done. Try to summarise your methods and evidence with a few keywords to keep if brief. Some examples include qualitative, quantitative, archival or experimental.
• Results – Here, you should summarise your outcomes and highlight what is new or significant about your findings.
• Conclusion – The conclusion should relate back to your rationale and research question. Ask yourself, ‘what do the results mean?’
• Implications and applications – Lastly, the reader needs to know why your results are important to the field. You need to specify what is significant about this work and how it can be useful.

Once you have your framework it can be edited for a more natural flow. You may find that some points naturally merge into one sentence and others need some elaboration. But remember, the abstract must be short and concise so don’t be tempted to extend areas unnecessarily. Once you have a draft that you are happy with, consider asking for feedback from other PhD students or your supervisor.

How to Write an Abstract for Your Thesis or Dissertation What is an Abstract? The abstract is an important component of your thesis. Presented at the beginning of the thesis, it is likely the first substantive description of your work read by an external examiner. You should view it as an opportunity to set accurate expectations. The abstract is a summary of the whole thesis. It presents all the major elements of your work in a highly condensed form. An abstract often functions, together with the thesis title, as a stand-alone text. Abstracts appear, absent the full text of the thesis, in bibliographic indexes such as PsycInfo. They may also be presented in announcements of the thesis examination. Most readers who encounter your abstract in a bibliographic database or receive an email announcing your research presentation will never retrieve the full text or attend the presentation. An abstract is not merely an introduction in the sense of a preface, preamble, or advance organizer that prepares the reader for the thesis. In addition to that function, it must be capable of substituting for the whole thesis when there is insufficient time and space for the full text. Size and Structure Currently, the maximum sizes for abstracts submitted to Canada's National Archive are 150 words (Masters thesis) and 350 words (Doctoral dissertation). To preserve visual coherence, you may wish to limit the abstract for your doctoral dissertation to one double-spaced page, about 280 words. The structure of the abstract should mirror the structure of the whole thesis, and should represent all its major elements. For example, if your thesis has five chapters (introduction, literature review, methodology, results, conclusion), there should be one or more sentences assigned to summarize each chapter. Clearly Specify Your Research Questions As in the thesis itself, your research questions are critical in ensuring that the abstract is coherent and logically structured. They form the skeleton to which other elements adhere. They should be presented near the beginning of the abstract. There is only room for one to three questions. If there are more than three major research questions in your thesis, you should consider restructuring them by reducing some to subsidiary status. Don't Forget the Results The most common error in abstracts is failure to present results. The primary function of your thesis (and by extension your abstract) is not to tell readers what you did, it is to tell them what you discovered. Other information, such as the account of your research methods, is needed mainly to back the claims you make about your results. Approximately the last half of the abstract should be dedicated to summarizing and interpreting your results. Updated 2008.09.11 © John C. Nesbit

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Scholars often write abstracts for various applications: conference presentations may require an abstract or other short summary for a program; journal articles almost always require abstracts; invited talks and lectures are often advertised using an abstract. While the application may necessarily change the length of the abstract (a conference program may only allow for 50-75 words, for instance), the purpose and structure remains fairly constant.

Abstracts are generally kept brief (approximately 150-200 words). They differ by field, but in general, they need to summarize the article so that readers can decide if it is relevant to their work. The typical abstract includes these elements:

• A statement of the problem and objectives
• A statement of the significance of the work
• A summary of employed methods or your research approach
• A summary of findings or conclusions of the study
• A description of the implications of the findings

Regardless of field, abstract authors should explain the purpose of the work, methods used, the results and the conclusions that can be drawn. However, each field purports slightly different ways to structure the abstract. A reliable strategy is to write the abstract as a condensed version of your article, with 1-2 sentences summarizing each major section. This means that in many of the sciences and a large portion of the humanities, abstracts follow a version of the IMRAD structure: Introduction, Methods, Results, and Discussion.

Most scientific journals require authors to submit such abstracts. It is generally advisable to write the abstract in the English language. That is because most papers in other languages, especially Asian nations, tend to publish an English abstract with common search engines, such as, the MLA site.

Example Abstract

This example abstract follows the IMRAD structure closely. The first two sentences are the introduction and background information. Sentences 3-5 describe the methods used in the study. Sentence 6 summarizes the results, while the last two sentences summarize the discussion and conclusion of the study; they also indicate the significance of the results.

Usability and User-Centered Theory for 21 st Century OWLs — by Dana Lynn Driscoll, H. Allen Brizee, Michael Salvo, and Morgan Sousa from The Handbook of Research on Virtual Workplaces and the New Nature of Business Practices . Eds. Kirk St. Amant and Pavel Zemlansky. Hershey, PA: Idea Group Publishing, 2008.

This article describes results of usability research conducted on the Purdue Online Writing Lab (OWL). The Purdue OWL is an information-rich educational website that provides free writing resources to users worldwide. Researchers conducted two generations of usability tests. In the first test, participants were asked to navigate the OWL and answer questions. Results of the first test and user-centered scholarship indicated that a more user-centered focus would improve usability. The second test asked participants to answer writing-related questions using both the OWL website and a user-centered OWL prototype. Participants took significantly less time to find information using the prototype and reported a more positive response to the user-centered prototype than the original OWL. Researchers conclude that a user-centered website is more effective and can be a model for information-rich online resources. Researchers also conclude that usability research can be a productive source of ideas, underscoring the need for participatory invention.

What is a dissertation abstract and how do I write one for my PhD?

Feb 12, 2019

There are a lot of posts that talk about how to write an abstract. Most say that you should write your abstract to impress your examiner.

We say that you need to flip things upside down: sure, your examiner will read it and want to see that you’ve written it well, but you should actually have your next boss in mind when you write it.

When you apply for your first academic job, the abstract may be the only part of your thesis that your new boss will read. They may not have the time or energy to read the whole thesis, so the abstract plays a crucial role. You should write it as if you academic career depends on it.

In this guide we talk about how to write an outstanding abstract that will (hopefully) land you a job.

If you haven’t already, make sure you download our PhD Writing Template , which you can use in conjunction with this guide to supercharge your PhD.

What is an abstract?

  This is fairly straightforward stuff, but let us be clear so we are all on the same page.

An abstract is a short summary at the beginning of the PhD that sums up the research, summarises the separate sections of the thesis and outlines the contribution.

It is typically used by those wishing to get a broad understanding of a piece of research prior to reading the entire thesis.

When you apply for your first academic job, the hiring manager will take a look through applicants’ abstracts (as well as your CV and covering letter) to create a shortlist. If you are lucky enough to do well at an interview, your potential new boss will take another look through it before deciding whether to offer you the job.

Why don’t they read the whole thing? Apart from the fact that they’re way too busy to read 200+ pages, a well written abstract actually contains all they need to know. It is a way of letting them see what your research is about, what contribution it makes, what your understanding of the field is and how or whether you will fit into the department.

So, you need to write it well.

But, don’t underestimate how hard it is to write a PhD thesis abstract. You have to condense hundred of pages and years of work into a few hundred words (exactly how many will depend on your university, so double check with them before you start writing).

How do I write a good PhD abstract?

Some blog posts use keywords to summarise the content (this one does, scroll down to see them). The abstract is similar. It’s an extended set of keywords to summarise a complex piece of research.

Above all, your PhD abstract should answer the question: ‘so what’ ? In other words, what is the contribution of your thesis to the field?

If you’ve been using our PhD writing template you’ll know that, to do this, your abstract should address six questions:

• What is the reason for writing the thesis?
• What are the current approaches and gaps in the literature?
• What are your research question(s) and aims?
• Which methodology have you used?
• What are the main findings?
• What are the main conclusions and implications?

One thing that should be obvious is that you can’t write your abstract until the study itself has been written. It’ll typically be the last thing you write (alongside the acknowledgements).

But how can I write a great one?

  The tricky thing about writing a great PhD abstract is that you haven’t got much space to answer the six questions above. There are a few things to consider though that will help to elevate your writing and make your abstract as efficient as possible:

• Give a good first impression by writing in short clear sentences
• Don’t repeat the title in the abstract
• Don’t cite references
• Use keywords from the document
• Respect the word limit
• Don’t be vague – the abstract should be a self contained summary of the research, so don’t introduce ambiguous words or complex terms
• Focus on just four or five essential points, concepts, or findings. Don’t, for example, try to explain your entire theoretical framework
• Edit it carefully. Make sure every word is relevant (you haven’t got room for wasted words) and that each sentence has maximum impact
• Avoid lengthy background information
• Don’t mention anything that isn’t discussed in the thesis
• Avoid overstatements
• Don’t spin your findings, contribution or significance to make your research sound grander or more influential that it actually is

Examples of a good and bad abstract

We can see that the bad abstract fails to answer the six questions posed above. It reads more like a PhD proposal, rather than a summary of a piece of research.

Specifically:

• It doesn’t discuss the reason why the thesis was written
• It doesn’t outline the gaps in the literature
• It doesn’t outline the research questions or aims
• It doesn’t discuss the methods
• It doesn’t discuss the findings
• It doesn’t discuss the conclusions and implications of the research.

It is also too short, lacks adequate keywords and introduces unnecessary detail. The abbreviations and references only serve to confuse the reader and the claim that the thesis will ‘develop a new theory of climate change’ is both vague and over-ambitious. The reader will see through this.

The good abstract though does a much better job at answering the six questions and summarising the research.

• The reason why the thesis was written is stated: ‘We do so to better enable policy makers and academics to understand the nuances of multi-level climate governance’ and….’it informs our theoretical understanding of climate governance by introducing a focus on local government hitherto lacking, and informs our empirical understanding of housing and recycling policy.’
• The gap is clearly defined: ‘The theory has neglected to account for the role of local governments.’
• The research question are laid out: ‘We ask to what extent and in what ways local governments in the UK’…
• The methods are hinted at: ‘Using a case study…’
• The findings are summarised: ‘We show that local governments are both implementers and interpreters of policy. We also show that they make innovative contributions to and influence the direction of national policy.’
• The conclusions and implications are clear: ‘The significance of this study is that it informs our theoretical understanding of climate governance by introducing a focus on local government hitherto lacking, and informs our empirical understanding of housing and recycling policy.’

This abstract is of a much better length, and it fully summarises what the thesis is about. We can see that if someone (i.e. your hiring manager) were to read just this abstract, they’d understand what your thesis is about and the contribution that it makes.

Your PhD thesis. All on one page. 

Use our free PhD structure template to quickly visualise every element of your thesis. 

I can’t summarise my thesis, what do I do?

  We suggest you fill out our PhD Writing Template . We’ve designed it so that you can visualise your PhD on one page and easily see the main components. It’s really easy to use. It asks you a few questions related to each section of your thesis. As you answer them, you develop a synopsis. You can use that synopsis to inform your abstract. If you haven’t downloaded it, you can find it here.

  Like everything related to writing, it takes practice before you get great at writing abstracts. Follow our tips and you’ll have a head start over others.

Remember, you’re not writing your abstract for anyone other than your hiring manager. Make sure it showcases the best of your research and shows your skills as both a researcher and a writer.

Thanks for the comment – I have sent you an email.

Hello! I am a Master’s student and I have applied for a PhD position. The professors have asked me to write a short abstract-like text, based on a brief sentence they will send me, related to the project study. How am I supposed to write a text like that when I don’t have the whole paper, the methods, results etc? Thank you in advance!

Hi Maria. I’m afraid that without knowing more about your topic or subject I am unable to give you advice on this. Sorry I can’t help in the way you may have hoped.

Thank u so much… your tips have really helped me to broaden my scope on the idea of how to write an abstract for my Ph.D. course. This is so thoughtful of you… The article is very informative and helpful…Thanks again!

Dissertation abstracts, by definition, are summaries of a thesis's content, usually between 200 and 300 words, used to inform readers about the contents of the study in a quick way. A thesis or dissertation abstract briefly overviews the entire thesis. Dissertation abstracts are found at the beginning of every study, providing the research recap, results, and conclusions. It usually goes right after your title page and before your dissertation table of contents . An abstract for a dissertation (alternatively called “précis” further in the article) should clearly state the main topic of your paper, its overall purpose, and any important research questions or findings. It should also contain any necessary keywords that direct readers to relevant information. In addition, it addresses any implications for further research that may stem from its field. Writing strong précis requires you to think carefully, as they are the critical components that attract readers to peruse your paper.

The primary purpose of an abstract in a dissertation or thesis is to give readers a basic understanding of the completed work. Also, it should create an interest in the topic to motivate readers to read further. Writing an abstract for a dissertation is essential for many reasons: 

In general, an abstract of a thesis or a dissertation is a bridge between the research and potential readers.

Making a good dissertation abstract requires excellent organization and clarity of thought. Proper specimens must provide convincing arguments supporting your thesis. Writing an effective dissertation abstract requires students to be concise and write engagingly. Below is a list of things that makes it outstanding:

Abstracts should be long enough to convey the key points of every thesis, yet brief enough to capture readers' attention. A dissertation abstract length should typically be between 200-300 words, i.e., 1 page. But usually, length is indicated in the requirements. Remember that your primary goal here is to provide an engaging and informative thesis summary. Note that following the instructions and templates set forth by your university will ensure your thesis or dissertation abstract meets the writing criteria and adheres to all relevant standards.

Dissertation abstracts can be organized in different ways and vary slightly depending on your work requirements. However, each abstract of a dissertation should incorporate elements like keywords, methods, results, and conclusions. The structure of a thesis or a dissertation abstract should account for the components included below:

Below is an example that shows how a dissertation abstract looks, how to structure it and where each part is located. Use this template to organize your own summary. 

There are several things you should do beforehand in order to write a good abstract for a dissertation or thesis. They include:

Remember, it's advisable to write an abstract for a thesis paper or dissertation last. Even though it’s always located in the beginning of the work, nevertheless, it should be written last. This way, your summary will be more accurate because the main argument and conclusions are already known when the work is mostly finished - it is incomparably easier to write a dissertation abstract after completing your thesis. Additionally, you should write it last because the contents and scope of the thesis may have changed during the writing process. So, create your dissertation abstract as a last step to help ensure that it precisely reflects the content of your project.

Writing dissertation abstracts requires careful attention to details and adherence to writing requirements. Refer to the rubric or guidelines that you were presented with to identify aspects to keep in mind and important elements, such as correct length and writing style, and then make sure to comprehensively include them. Careful consideration of these requirements ensures that your writing meets every criterion and standard provided by your supervisor to increase the chances that your master's thesis is accepted and approved.   

Before starting to write a dissertation or thesis abstract you should choose the appropriate type. Several options are available, and it is essential to pick one that best suits your dissertation's subject. Depending on their purpose, there exist 3 types of dissertation abstracts: 

Informative one offers readers a concise overview of your research, its purpose, and any relevant background information. Additionally, this type includes brief summaries of all results and dissertation conclusions .  A descriptive abstract in a dissertation or thesis provides a quick overview of the research, but it doesn't incorporate any evaluation or analysis because it only offers a snapshot of the study and makes no claims.

Critical abstract gives readers an in-depth overview of the research and include an evaluative component. This means that this type also summarizes and analyzes research data, discusses implications, and makes claims about the achievements of your study. In addition, it examines the research data and recounts its implications. 

Choose the correct type of dissertation abstract to ensure that it meets your paper’s demands.

Writing a good abstract for a dissertation or thesis is essential as it provides a brief overview of the completed research. So, how to write a dissertation abstract? First of all, the right approach is dictated by an institution's specific requirements. However, a basic structure should include the title, an introduction to your topic, research methodology, findings, and conclusions. Composing noteworthy precis allows you to flaunt your capabilities and grants readers a concise glimpse of the research. Doing this can make an immense impact on those reviewing your paper.

An abstract for thesis paper or dissertation is mainly dependent on the purpose of your study. Students need to identify all goals and objectives of their research before writing their précis - the reason being to ensure that the investigation’s progress and all its consequent findings are described simply and intelligibly. Additionally, one should provide some background information about their study. A short general description helps your reader acknowledge and connect with the research question. But don’t dive too deep into details, since more details are provided when writing a dissertation introduction . Scholars should write every dissertation abstract accurately and in a coherent way to demonstrate their knowledge and understanding of the area. This is the first section that potential readers will see, and it should serve as a precise overview of an entire document. Therefore, researchers writing abstracts of a thesis or dissertation should do it with great care and attention to details.

A writer needs to elaborate on their methodological approach in an abstract of PhD dissertation since it acts as a brief summary of a whole research and should include an explanation of all methods used there. Dissertation and thesis abstracts discuss the research methodology by providing information sufficient enough to understand the underlying research question, data collection methods, and approach employed. Additionally, they should explain the analysis or interpretation of the data. This will help readers to gain a much better understanding of the research process and allow them to evaluate the data quality. Mention whether your methodology is quantitative or qualitative since this information is essential for readers to grasp your study's context and scope. Additionally, comment on the sources used and any other evidence collected. Furthermore, explain why you chose the method in the first place. All in all, addressing methodology is a crucial part of writing abstracts of a thesis or dissertation, as it will allow people to understand exactly how you arrived at your conclusions.

Write your abstract for dissertation in a way that includes an overview of the research problem, your proposed solution, and any limitations or constraints you faced. Students need to briefly and clearly describe all key findings from the research. You must ensure that the results mentioned in an abstract of a thesis or dissertation are supported with evidence from body chapters.  Write about any crucial trends or patterns that emerged from the study. They should be discussed in detail, as this information can often provide valuable insight into your topic. Be sure to include any correlations or relationships found as a result of the study. Correlation, in this context, refers to any association between two or more variables.  Finally, write about any implications or conclusions drawn from your results: this is an essential element when writing an abstract for dissertation since it allows readers to firmly comprehend the study’s significance.

Knowing how to write an abstract for dissertation is critical in conveying your work to a broad audience. Summarizing can be challenging (since precis is a summary in itself), but it is an essential part of any successful work. So, as a final step, conclude this section with a brief overview of the topic, outline the course of your research and its main results, and answer the paper’s central question.  Summarizing an abstract of your dissertation is done to give readers a succinct impression of the entire paper, making an accurate and concise overview of all its key points and consequent conclusions. In every PhD dissertation abstract , wrap up its summary by addressing any unanswered questions and discussing any potential implications of the research.

Format depends on the style (APA, MLA, Harvard, Chicago), which varies according to your subject's discipline. Style to use is usually mentioned in the instructions, and students should follow them closely to ensure formatting accuracy. These styles have guidelines that inform you about the formatting of titles, headings and subheadings, margins, page numbers, abstracts, and tell what font size and family or line spacing are required. Using a consistent formatting style ensures proper readability and might even influence paper’s overall structure. Another formatting concern to consider when writing dissertation and thesis abstracts is their layout. Most commonly, your paper should have a one-inch margin on all sides with double spacing. Be sure to familiarize yourself with the right guidelines to get the correct information on how to write dissertation abstract in APA format and ensure that it meets formatting standards.

When writing thesis abstracts, it is essential to include keywords. Keywords are phrases or words that help readers identify main topics of your paper and make it easier for them to find any information they need. Keywords should usually be placed at the end of a dissertation abstract and written in italics. In addition, include keywords that represent your paper's primary research interests and topics. Lastly, use keywords throughout your thesis to ensure that your précis accurately reflect an entire paper's content.

When writing, checking out thesis and dissertation abstracts examples from experts can provide a valuable reference point for structuring and formatting your own précis. When searching for an excellent sample template, engaging the assistance of a professional writer can be highly beneficial. Their expertise and knowledge offer helpful insight into creating an exemplary document that exceeds all expectations. Examples of dissertation abstracts from different topics are commonly available in scholarly journals and websites. We also encourage you to go and search your university or other local library catalogue -  multiple useful samples can surely be found there.

Writing A Dissertation Or Thesis Abstract

5 Common (& Costly) Mistakes To Avoid

By: David Phair (PhD) & Peter Quella (PhD) | February 2022

Writing a quality abstract is important as the abstract tells the reader what to expect in your thesis or dissertation, and it helps them to decide whether they should read the rest of your document. Over the years, we’ve reviewed thousands of abstracts . In this post, we’ll unpack five common mistakes we see and explain how you can avoid them when crafting your dissertation or thesis abstract.

Overview: 5 Abstract Mistakes

• Not understanding exactly what an abstract is (and does)
• Failing to cover the key aspects of your study
• Using body content verbatim instead of paraphrasing
• Having formatting and language -related issues
• Failing to include relevant keywords

1. Not understanding what an abstract is

A recurring issue we see is that students often don’t have a clear understanding of what an abstract is and the purpose it serves . This naturally has a major knock-on effect. Simply put, an abstract is a concise summary of your research project , and it should include a bit of everything from your thesis or dissertation. The purpose of the abstract is to tell the reader what to expect in your document and entice them to read the full document (or at least the parts that are relevant to them).

A good abstract should summarize the key components of your study, which means that it should include a brief introduction to your study, a summary of the key insights from your literature review, a high-level overview of your methodology , and a summary of the key findings . Importantly, your abstract should summarise the body content, not present new information . Never present any information in your abstract that is not presented in your main document.

When writing up your abstract, aim to do so as concisely as possible. You can think of your abstract as an elevator pitch – you want it to be short, sweet and representative of everything you want to get across. Less is more. Also, much like an elevator pitch, your abstract needs to tell a clear story on its own. So, it’s vital to create a clear narrative within your abstract that paints a vivid picture in the reader’s mind.

2. Not covering the key aspects of your study

Another common mistake we see students making is not covering the key aspects of their studies in the abstract. While you don’t have much space to work with, an abstract still needs to cover the main details of your study. So, when you’re crafting this section, try to allocate 2-3 sentences toward each of your chapters.

Importantly, your abstract needs to explain what your study focuses on (i.e., your research aims and questions ) and how that is unique and important . In other words, it needs to justify your research . To do this, you can mention how your research connects to prior studies, and what differences justify the existence of your project. This should be rooted in the content presented in your introduction and literature review chapters.

The abstract should also provide insight regarding the methodological approach . Remember, the abstract is a summary, so while it’s important to outline your research methodology, don’t try to detail the entire design here. You just need to cover the high-level details , such as the methodological approach (e.g., qualitative), sampling strategy , data collection and data analysis methods.

Finally, your abstract needs to discuss your key findings and the implications thereof . It should address questions such as:

• What did you find?
• Why is it important?
• What implications (and applications) are there for your findings?

The word “key” is vital here – you don’t have to discuss every finding , just the ones that are central to your research aims and research questions.

3. Using body content verbatim

Since the abstract is a summary of your work, you’ll generally write it last (although you can of course create an outline earlier in the dissertation writing process). Because of this, there is a tendency amongst students to copy and paste content from their body chapters (e.g., the literature review chapter, methodology chapter, etc.) to create an abstract. This is problematic, as the abstract needs to be an original piece of writing , not a hodgepodge of the existing body content.

A good abstract should present a be a smooth, clear narrative of what you set out to discover (i.e., the research topic and justification), how you approached it (i.e., the methodology), and what the results were. Importantly, you need to tell an engaging story with your abstract, as that is what will attract them to read the rest of your thesis or dissertation. To achieve this, you cannot simply copy-paste content from the body section of your document. You need to craft a unique piece of content that can stand alone and engage potential readers with an enticing narrative.

All that said, when crafting your abstract, a good starting point can be to copy-paste some key insights from each chapter so that you have everything in one place. You could, for example, have a few bullet points for each chapter. However, that is purely a starting point . From there, you need to craft an original piece of writing that will form a smooth, engaging narrative.

4. Formatting and language-related issues

Another common issue we encounter is that of formatting and language -related issues in abstracts. Understandably, students are generally quite worn out by this stage of the dissertation and may slip up on the finer details. However, the abstract is your “shop window” – the first thing a new reader will encounter – so it needs to be very well polished . If you write a brilliant abstract but it’s riddled with spelling and grammar issues, you’re going to lose the reader’s interest (and, of course, marks).

So, what sort of issues do you need to avoid?

First – typically, an abstract doesn’t make use of citations , as these are reserved for the body content of the dissertation or thesis. However, you can use author names when referring to seminal work. For example, if your study is a response to prior research, you can name the researchers (but you don’t need to include a full citation). Of course, it’s worth noting that some institutions may have a different preference, so be sure to look at past dissertations and theses from your university program to gauge what the norms are.

Second – when writing up your abstract, try to avoid using excessive jargon , complex terminology and abbreviations. Always assume that you are writing for the intelligent layman . In other words, an intellectually curious outsider to your field of research. Ultimately, your abstract needs to be understandable to your audience and using excessive jargon or complex terminology may lose the reader . If you must use jargon or abbreviations to accurately represent a concept, be sure to explain each piece of terminology first.

Third – since your abstract needs to be concise, it can be tempting to write using bullet points and numbered lists. Typically, however, an abstract shouldn’t have bullet points , numbered lists, figures, or tables as it is a textual summary. So, avoid these at all costs.

Lastly – it may sound obvious, but your abstract needs to be “perfect” in terms of language use. All too often, we see spelling, punctuation, grammar and tense errors in the abstract. Since it is your “shop window”, these types of issues are inexcusable. So, be sure to carefully edit and proofread your abstract before submission.

5. Not including relevant keywords

Another common mistake that we see students make is not including relevant keywords at the end of the abstract. Sometimes the keywords aren’t relevant, and sometimes they’re just altogether absent.

But what exactly are keywords?

Keywords are what make your research discoverable in search engines and academic databases – they’re like academic hashtags that connect research and make it possible to navigate through similar studies. An example of a keyword would be something like, “cognition” or “addiction”.

Typically, keywords can be quite vague or broad , so you’ll likely need to make use of key phrases to more accurately represent your research. Key phrases consist of multiple keywords, for example, “temporal cognition” or “Dutch sentence negation”. While key phrases provide more specificity than individual keywords, never use whole sentences as key phrases, these just look bad and make your research very hard to find. Ideally, you should try to stick to key phrases of 2-3 words.

In general, you should aim for 5-6 keywords/key phrases for your research project. However, it’s always a good idea to check with your institution to find out how many keywords/phrases they prefer. While it may be tempting to go full Instagram and use every keyword you can come up with, this is not advised as this can make your research look like it lacks credibility and specificity . It can also appear that you’re trying to game the system.

To identify relevant keywords, think about the research process and the kinds of search terms you used when performing your literature review, as these terms are a good start. Further, have a look at the keywords used in previous studies (i.e., the journal articles you read as part of your literature review) to identify relevant keywords.

How to Craft a Killer Dissertation Abstract 2023

Learn how you can write a top-rated dissertation abstract thick and fast, with our professional guide.

Special tip – maintain a hawk-eye to the end.

What is an Abstract in a Dissertation?

A dissertation abstract is a summary of the entire thesis. It gives the significant proponents of your paper in a highly condensed form.

An abstract in a dissertation serves the following functions:

• Acts as an introduction to your dissertation article
• Sets the stage for the thesis
• Can substitute the whole thesis

The elements of an abstract include:

• Research problem and objectives
• Major results
• The conclusion

It is an essential component of the thesis that can either earn you a top grade or be the reason for your academic downfall.

How to Write a Dissertation Abstract

It is essential to determine the type of abstract for your dissertation. In writing a dissertation abstract, take note of the following types:

• Descriptive Abstract

It gives the kind of information found in your paper. A descriptive outline is usually concise and can be about 100 words or less.

• Critical Abstract

It describes the main findings and, additionally, a comment on the validity, completeness, or reliability of the study. Due to its interpretive nature, it generally contains 400-500 words in length.

• Informative Abstract

As the name suggests, this type presents and explains the main arguments, essential results, and evidence in the thesis. Although the length varies, it is not more than 300 words in length.

• Highlight Abstract

It serves to attract the reader’s attention to the paper. It uses leading remarks to spark the interest of the audience.

We are now going to see how to write an abstract for a dissertation in ten significant steps:

Ten Top-Notch Steps to Writing an Abstract for a Dissertation

Step 1: Define the purpose of your research

Start by making plain the purpose of your study. State the research question you are going to handle or the practical problem of your paper.

Do not delve into much detailed information here. For starters, you can have a brief context on the social or academic relevance of your topic.

Write the objectives of your research after stating the problem. When indicating the goals, use verbs such as:

To test To investigate, To evaluate To analyze

Use either the present or simple past tense for this section. Do not use the future tense in any case since the research is complete already.

Dissertation abstract example for this section:

Correct: This study evaluates the relationship between COVID-19 and flu. Incorrect: This study will determine the relationship between COVID-19 and influenza.

Step 2: Identify the methods you are going to use for your research

Now in this stage, clearly make mention of the ways you are going to use to answer your research question.

Write it in one to two sentences without making it too long. Ensure that the points are precise and to the end.

It should be in the simple past tense. Why? Because you have already done your research and completed it using these methods.

Do not go into the strengths and weaknesses of the research methods. The reader should be able to read through it fast and still understand the strategy and methodology of your thesis.

Correct: Direct observation was conducted on 40 COVID-19 patients. Correct: Questionnaires were administered to 20 doctors dealing with COVID-19 patients. Incorrect: Laboratory experiments will be done with ten specimens.

Step 3: Make a summary of the results

After collecting data, it is time to give brief but elaborate results in the abstract for the dissertation.

The results section depends on the length and complexity of the research. However, ensure that it doesn’t make the abstract longer than is recommended.

Do not include irrelevant results which may not add any value to your paper. Strive to point out the essential outcomes of the article which support or answer your research question.

Write the results in either the present or simple past tense.

Correct: Our findings show a substantial similarity in the symptoms of both COVID-19 and flu. Correct: Our analysis showed a significant similarity between the symptoms of both COVID-19 and flu. Incorrect: Our study has shown a considerable similarity in the symptoms of both COVID-19 and flu. Incorrect: Our findings will be showing a substantial similarity in the symptoms of both COVID-19 and flu.

Step 4: Finish off with the conclusions from your research

Your abstract should have an answer to the research question, which is in this part. Your reader should get the main point of your thesis at this point. What has your research found or proved? The conclusion should be able to tell this to the reader.

Improve the credibility of your dissertation by adding any relevant limitations in this section of the abstract. From the thesis abstract examples, we are going to see below; it is evident that the conclusion is as brief as possible.

You can also have recommendations or suggestions for further research in your conclusion. Nevertheless, they should be as brief as possible. Do not write a long list that will interfere with the length of the abstract.

Write the conclusion in the present simple tense. Here are examples for your inspiration:

Correct: We conclude that flu is a primary symptom of COVID-19. Incorrect: We found that influenza is a primary symptom of COVID-19.

Bonus Tips for Writing a Dissertation Abstract

Now that we have looked at the essential steps to follow, here are some expert tips to crank up your abstract:

Follow the recommended formatting requirements for the abstract. The format will include; word limit, length, and spacing, style (APA, MLA, etc.)

The standard formatting requires that you do not write more than one double-spaced page.

• Avoid verbosity

Each word in a sentence counts due to the brevity of an abstract. Therefore, use short but communicating sentences.

Do not add unnecessary words or jargon, as this will obscure your abstract. Remember that the reader should be able to understand your abstract in the shortest time possible.

Ensure that you maintain the proper balance between the different elements of the abstract.

Checklist for Writing an Abstract

• The type of abstract identified
• The conformity of the abstract to the conventions of the type chosen
• Is the problem interesting to write on
• What is your approach? (Prototype models, analytical models, etc.)
• What’s the answer (results)
• What is the implication of your solution? (Conclusion)

Writing a successful abstract requires both hard work and determination, but its fruits are worth the struggle. As you plan to write yours, ensure that all the elements discussed above appear in your paper.

What is Dissertation Abstracts?

Let's break this question down into a few smaller questions.

• What is an abstract? An abstract is a small summary of a longer piece of written work.
• What is a dissertation? A dissertation, sometimes called a thesis, is a research project conducted and written by a person who is a candidate for graduating from a higher education institution for a master's or doctoral degree. On rare occasions, a dissertation or thesis may be written by a bachelor's candidate.
• So what is Dissertation Abstracts? Dissertation Abstracts is a specific publication that prints only the abstracts of doctoral dissertations. Its purpose is to allow researchers to remain current with what other people in their field are studying by providing short summaries of dissertations that have been published.

Dissertation Abstracts provides ONLY the abstract, not the entire dissertation. Entire dissertations must be requested through Interlibrary Loan separately.

Determining if you really want the dissertation abstract

• The abstract MAY NOT be useful to you if you are conducting regular, undergraduate level research. You probably should find a different source.
• The abstract MAY be useful to you if you are trying to decide if you need to consult (therefore, Interlibrary Loan) the entire dissertation for your research. If you are an upper-level undergraduate, Master's, Doctoral, or faculty member conducting research, you may wish to read the entire dissertation. See below for instructions on requesting a full-length dissertation.

Requesting the full-length dissertation

To request an Interlibrary Loan of an entire dissertation, log in to your  ILLiad account .

• In the upper left hand corner, under "Create New Request" click on "Other Items."
• In the Citation section for "Describe the Item that you want" include dissertation title, dissertation author, year of publication, and any other information you may have, including the school where the dissertation was published.
• In the Citation section for "Where did you learn about this item" include where the citation to the dissertation was found, such as Dissertation Abstracts volume 71, issue 7.
• Set your "Not Wanted After" date.
• Click Submit Information.

Please note that not all dissertations are available for Interlibrary Loan. Some that are available may not be available for free. We will notify you before attempting to obtain a copy that is not free.   Please email [email protected] with any questions.

Dissertation abstract

Despite being just 150 to 350 words long (in most cases), the Abstract is arguably one of the most important parts of your dissertation. In this short space, the abstract must capture the essence of your dissertation. This includes the problem being tackled (and the motivation behind this), the significance of your research, the research strategy guiding it, as well as the major findings and conclusions. The perfect informative abstract is one where the reader could choose not to read on but would still understand the essence of your dissertation. At the same time, a poorly constructed dissertation abstract can mislead the reader into thinking the study is about something it is not, confusing them from the very start.

In most cases, you will be expected to use an informative , rather than descriptive style , when writing your dissertation abstract. However, since this is not always the case, we briefly explain the difference between the two abstract styles - descriptive and informative - in the section, Choosing between dissertation abstract styles: Descriptive or informative . With the abstract being one of the most important parts of your dissertation, we explain the need for good structure, internal consistency, effective weighting between sections, amongst other factors, in the section, What readers expect from a dissertation abstract . We also highlight what readers are not looking for.

Even though every dissertation is different, there is a fairly common way to effectively structure your dissertation abstract. In the section, How to structure your dissertation abstract , we take you through the important components that the abstract should address, including the problem being addressed, the significance of the study, components of your research strategy, results and conclusions. Finally, knowing what you want to say and how to express that on the page are two different things. In the section, Useful phrases when writing a dissertation abstract , we set out phrases that you can use and build on when writing your dissertation abstract.

Towards Manipulator Task-Oriented Programming: Automating Behavior-Tree Configuration

Task-oriented programming is a way of programming manipulators in terms of high-level tasks instead of explicit motions. It has been a long-standing vision in robotics since its early days. Despite its potential, several challenges have hindered its full realization. This thesis identifies three major challenges, particularly in task specification and the planning-to-execution transition: 1) The absence of natural language integration in system input. 2) The dilemma of continuously developing non-uniform and domain-specific primitive-task libraries. 3) The requirement for much human intervention.

To overcome these difficulties, this thesis introduces a novel approach that integrates natural language inputs, eliminates the need on fixed primitive-task libraries, and minimizes human intervention. It adopts the behavior tree, a modular and user-friendly form, as the task representation and advances its usage in task specification and planning-to-execution transition. The thesis is structured into two parts – Task Specification and Planning-to-Execution Transition.

Task specification explores the use of large language models to generate a behavior tree from an end-user's input. A Phase-Step prompt is designed to enable the automatic behavior-tree generation from end-user's abstract task descriptions in natural languages. With the powerful generalizability of large language models, it breaks the dilemma that stays with fixed primitive-task libraries in task generation. A full-process case study demonstrated the proposed approach. An ablation study was conducted to evaluate the effectiveness of the Phase-Step prompts. Task specification also proposes behavior-tree embeddings to facilitate the retrieval-augmented generation of behavior trees. The integration of behavior-tree embeddings not only eliminates the need for manual prompt configuration but also provides a way to incorporate external domain knowledge into the generation process. Three types of evaluations were performed to assess the performance of the behavior-tree embedding method.

Planning-to-execution transition explores how to transit primitive tasks from task specification into manipulator executions. Two types of primitive tasks are considered separately: point-to-point movement tasks and object-interaction tasks. For point-to-point movement tasks, a behavior-tree reward is proposed to enable reinforcement learning over low-level movement while following high-level running order of the behavior tree. End-users only need to specify rewards on the primitive tasks over the behavior tree, and the rest of the process will be handled automatically. A 2D space movement simulation was provided to justify the approach. For object-interaction tasks, the planning-to-execution transition uses a large-language-model-based generation approach. This approach takes natural-language-described primitive tasks as input and directly produces task-frame-formalism set-points. Combined with hybrid position/force control systems, a transition process from primitive tasks directly into joint-level execution can be realized. Evaluations over a set of 30 primitive tasks were conducted.

Overall, this thesis proposes an approach that advances the behavior-tree towards automated task specification and planning-to-execution transitions. It opens up new possibilities for building better task-oriented manipulator programming systems.

Using Remote Sensing to Monitor Water Quality in Climate and Wildfire Stressed California Reservoirs Abstract    The increasing frequency of cyanobacterial harmful algal blooms (cyanoHABs) in California’s (CA) inland waters pose significant risks to public health and recreational water use. Wildfires may increase nutrient runoff and alter water temperature and light conditions, promoting cyanoHABs. Understanding these effects are essential as wildfires become more frequent and severe in CA. This dissertation leverages satellite remote sensing (SRS) to monitor cyanoHABs, quantify their temporal and spatial trends at a large scale, and explore the role of wildfire as a driver of cyanoHABs of the entire state of CA. My findings show that public health alerts derived from SRS and World Health Organization guidelines have high rates of correspondence with public health advisories issued by state authorities that are based on laboratory toxin analyses. SRS provided temporally dense and spatially explicit data, consistent across large scales, which is essential for timely cyanotoxin risk assessments, and could be used to enhance traditional in-situ sampling. My work shows that cyanoHABs have increased from 2016 to 2022 compared to 2008 to 2012. Although most lakes in CA did not exhibit changes in cyanoHAB alerts following wildfire events, there are several lakes that have shown a statistically significant increase in cyanoHAB alerts after severe wildfires; all of these events have occurred in the more recent era of this study, suggesting that increasing wildfire frequency and severity may be introducing an additional public health threat. This is the first time a study of this nature has been conducted at such a large scale, enabled by SRS. My findings underscore the need for more large-scale studies and long-term monitoring to address the effects of changing climate and wildfires on water quality and risks to public health. Biography    Brittany Lopez Barreto received her B.S. in Environmental Science and Management with a focus on watershed science. She was awarded the prestigious Future Investigators in NASA Earth and Space Science and Technology (FINESST) grant for her dissertation research. Brittany’s research interests center on using remote sensing to monitor surface water quality for public health, particularly the impacts of wildfire and climate change. Born and educated in California, Brittany will continue to focus her research in the state. She enjoys spending quality time with family and friends, cooking, engaging with anything horror-related, and being near water.

Title : Model-driven discovery through a whole-cell computational model of Escherichia coli

Abstract : Throughout many scientific and engineering disciplines, mathematical models have been pivotal in helping scientists and engineers better understand complicated systems, develop hypotheses, predict behaviors, and make model-guided discoveries. The E. coli whole-cell modeling project aims to bring this approach into biology by constructing a detailed mathematical representation of the most well-characterized system in biology — the E. coli cell. The whole-cell model is composed of multiple, smaller submodels that each represent a particular biological process within an E. coli cell, which are then integrated into a larger model that can simulate the growth of the entire cell under multiple environments. In total, the model incorporates more than 19,000 heterogeneous parameters gathered from decades of research performed on this model organism. The whole-cell modeling team within the Covert Lab has been leading this project for more than ten years.

In my Ph.D. defense, I will first describe how the E. coli whole-cell model was built and our general strategy for using the model in model-driven discovery. Next, I will share my efforts in building data pipelines between the whole-cell model and EcoCyc, the largest online database for E. coli, to streamline the curation of model parameters and broadly share the model outputs to the scientific community. Lastly, I will present how the whole-cell model was updated to account for E. coli's transcription unit structures, and highlight the discoveries I made during this process.

The 1952 Ph.D. dissertation of T.F.W. Embleton on nonlinear acoustic propagation and reflection

• Sparrow, Victor W.

In his doctoral research Tony Embleton studied nonlinear acoustics experimentally using techniques available in the Physics Department of Imperial College, University of London. Originally developed by V. Timbrell, the interferometric equipment was substantially improved by Tony Embleton, enabling his Ph.D. findings. Studying propagation in a tube and reflection by both closed and open ends, Tony Embleton was able to substantially confirm the theory of the time, developed by Stokes, Earnshaw, Rankine, Rayleigh, and Taylor, many pieces confirmed for the first time. He also found discrepancies regarding the attenuation coefficients regarding the first and second half cycle of each pulse as well as a shortening of a pulse at reflection from a closed end. These findings are still worthy of further investigation. The results of reflection of pulses from the open end of a tube, forming a pressure release boundary condition, still are very interesting to the present author. A pulse propagating toward the open end steepens, but the reflected wave "unsteepens" which is a unique nonlinear acoustic phenomenon.
