Tenses can be tricky to master. Even well respected journals differ in the guidance they give their authors for their use. However, their are some general conventions about what tenses are used in different parts of the report/dissertation. This page gives some advice on standard practice.

What tenses will you use?

There are exceptions however, most notably in the literature review where you will use a mixture of past , present and present perfect tenses (don't worry, that is explained below), when discussing the implications of your findings when the present tense is appropriate and in the recommendations where you are likely to use the future tense.

The tenses used as standard practice in each of these sections of your report are given and explained below.

In your abstract

You have some leeway with tense use in your abstract and guidance does vary which can sometimes be confusing. We recommend the following:

Describing the current situation and reason for your study

Mostly use the present tense,  i.e. "This is the current state of affairs and this is why this study is needed."

Occasionally, you may find the need to use something called the present perfect tense when you are describing things that happened in the past but are still relevant. The present perfect tense uses have/has and then the past participle of the verb i.e. Previous research on this topic has focused on... 

Describing the aims of your study

Here you have a choice. It is perfectly acceptable to use either the present or past tense,  i.e. "This study aims to..." or "This study aimed to..." 

Describing your methodology

Use the past tense to describe what you did, i.e. "A qualitative approach was used." "A survey was undertaken to ...". "The blood sample was analysed by..."

Describing your findings

Use the past tense to describe what you found as it is specific to your study, i.e. "The results showed that...", "The analysis indicated that..."

Suggesting the implications of your study

Use the present tense as even though your study took place in the past, your implications remain relevant in the present, i.e. Results revealed x which indicates that..."

Example abstract 

An example abstract with reasoning for the tenses chosen can be found at the bottom of this excellent blog post: 

Using the Present Tense and Past Tense When Writing an Abstract

In your methodology

The methodology is one of the easiest sections when it comes to tenses as you are explaining to your reader what you did. This is therefore almost exclusively written in the past tense.

Blood specimens were frozen at -80 o C.

A survey was designed using the Jisc Surveys tool.

Participants were purposefully selected.

The following search strategy was used to search the literature:

Very occasionally you may use the present tense if you are justifying a decision you have taken (as the justification is still valid, not just at the time you made the decision). For example: 

Purposeful sampling was used to ensure that a range of views were included. This sampling method maximises efficiency and validity as it identifies information-rich cases and ... (Morse & Niehaus, 2009).

In your discussion/conclusion

This will primarily be written in the present tense as you are generally discussing or making conclusions about the relevance of your findings at the present time. So you may write:

The findings of this research suggest that.../are potentially important because.../could open a new avenue for further research...

There will also be times when you use the past tense , especially when referring to part of your own research or previous published research research - but this is usually followed by something in the present tense to indicate the current relevance or the future tense to indicate possible future directions:

Analysis of the survey results found most respondents were not concerned with the processes, just the outcome. This suggests that managers should focus on...

These findings mirrored those of Cheung (2020), who also found that ESL pupils failed to understand some basic yet fundamental instructions. Addressing this will help ensure...

In your introduction

The introduction generally introduces what is in the rest of your document as is therefore describing the present situation and so uses the present tense :

Chapter 3  describes  the research methodology.

Depending on your discipline, your introduction may also review the literature so please also see that section below.

In your literature review

The findings of some literature may only be applicable in the specific circumstances that the research was undertaken and so need grounding to that study. Conversely, the findings of other literature may now be accepted as established knowledge. Also, you may consider the findings of older literature to be still relevant and relatively recent literature be already superseded. The tenses you write in will help to indicate a lot of this to the reader. In other words, you will use a mix of tenses in your review depending on what you are implying.

Findings only applicable in the specific circumstances

Use the past tense . For example: 

In an early study, Sharkey et al. (1991)  found  that isoprene emissions  were doubled  in leaves on sunnier sides of oak and aspen trees. 

Using the past tense indicates that you are not implying that isoprene emissions are always doubled on the sunnier side of the trees, just that is what was found in the Sharkey et al. study.

Findings that are still relevant or now established knowledge

Mostly use the present tense , unless the study is not recent and the authors are the subject of the sentence (which you should use very sparingly in a literature review) when you may need to use a mixture of the past and present. For example:

A narrowing of what 'graduateness' represents damages students’ abilities to thrive as they move through what will almost certainly be complex career pathways (Holmes, 2001).

Holmes (2001) argued strongly that a narrowing of what 'graduateness' represents damages  students’ abilities to thrive as they move through what will almost certainly be complex career pathways

Both of these imply that you think this is still the case (although it is perhaps more strongly implied in the first example). You may also want to use some academic caution too - such as writing 'may damage' rather than the more definite 'damages'.

Presenting your results

As with your methodology, your results section should be written in the past tense . This indicates that you are accepting that the results are specific to your research. Whilst they may have current implications, that part will not be considered until your discussion/conclusions section(s).

Four main themes were identified from the interview data.

There was a significant change in oxygen levels.

Like with the methodology, you will occasionally switch to present tense to write things like "Table 3.4 shows that ..." but generally, stick to the past tense.

In your recommendations

Not everyone will need to include recommendations and some may have them as part of the conclusions chapter. Recommendations are written in a mixture of the present tense and  future tense :

It is recommended that ward layout is adapted, where possible, to provide low-sensory bays for patients with autism. These will still be useable by all patients but...

How to write a PhD in a hundred steps (or more)

A workingmumscholar's journey through her phd and beyond, changing tenses as you write your dissertation.

The PhD student I am supervising sent the first draft of her methodology chapter yesterday with a series of questions and notes for me and the co-supervisor. One of them was about tense: she is writing everything in the present and future tense, but wondered if this was a mistake. It got me thinking (again) about tense in the PhD thesis , and the process of moving from future to past as the project progresses.

I have written here a little about the gap between the logic of discovery and the logic of display or dissemination in writing. As you are working, everything is either ‘I am doing this’ and ‘I will be doing that eventually’. This is pretty much the tense in which you write your proposal – proposals are forward  looking. So, as you start you research, you will naturally be thinking now, and on to the next steps, and your writing will most likely reflect this in the tenses you choose. This is the logic of discovery . As you move along, you will make decisions, close some doors, open others , and your argument will unfold and form as you do so.

So what to do now, in the midst of your research and writing – can and should you anticipate being finished and therefore writing everything in the methodology in the past tense, or do you worry about that later? It does seem like more work to write in the voice of discovery while you are still discovering things, and then write again later in the voice of dissemination as you reorganise and display your thinking with the benefit of (some) hindsight. However, I would caution against trying to anticipate too much . A significant part of doing a PhD is the process of doing a piece of research, and learning through missteps, successes and issues like the one discussed here how doing and writing about research feels and looks and sounds. That way, you can go on to do further research, either on your own or with others post-PhD, and you can eventually supervise PhD students yourself.

So my advice, if you are stuck in a similar spot to my PhD student is this: be where you are . Think and write your way through this patch, and write in whatever tense and voice feels most authentic to you at this point. The good news is that there will be time for rewriting, polishing and updating before you submit, and it’s quite a pleasant feeling to go back to this methodology chapter after the findings have been presented and analysed, and find that you can edit, sharpen and focus that section to create a tight, accurate and interesting narrative about the nuts and bolts of your PhD. As you do so, every time you do so, your researcher capacity and voice and ability to add to the conversation through the knowledge you are making grows, and that is what being an academic researcher is about.

How to Use Tenses within Scientific Writing

Written by: Chloe Collier

One’s tense will vary depending on what one is trying to convey within their paper or section of their paper. For example, the tense may change between the methods section and the discussion section.

Abstract --> Past tense

• The abstract is usually in the past tense due to it showing what has already been studied.

Example: “This study was conducted at the Iyarina Field School, and within the indigenous Waorani community within Yasuni National Park region.”

Introduction --> Present tense

• Example: “ Clidemia heterophylla and Piperaceae musteum are both plants with ant domata, meaning that there is an ant mutualism which protects them from a higher level of herbivory.”

Methods --> Past tense

• In the methods section one would use past tense due to what they have done was in the past.
• It has been debated whether one should use active or passive voice. The scientific journal Nature states that one should use active voice as to convey the concepts more directly.
• Example: “In the geographic areas selected for the study, ten random focal plants were selected as points for the study.”

Results --> Past tense

• Example: “We observed that there was no significant statistical difference in herbivory on Piperaceae between the two locations, Yasuni National Park, Ecuador (01° 10’ 11, 13”S and 77° 10’ 01. 47 NW) and Iyarina Field School, Ecuador (01° 02’ 35.2” S and 77° 43’ 02. 45” W), with the one exception being that there was found to be a statistical significance in the number count within a one-meter radius of Piperaceae musteum (Piperaceae).”

Discussion --> Present tense and past tense

• Example: “Symbiotic ant mutualistic relationships within species will defend their host plant since the plant provides them with food. In the case of Melastomataceae, they have swellings at the base of their petioles that house the ants and aid to protect them from herbivores.”
• One would use past tense to summarize one’s results
• Example: “In the future to further this experiment, we would expand this project and expand our sample size in order to have a more solid base for our findings.”

Verb Tenses in Academic Writing | Rules, Differences & Examples

Published on 20 October 2022 by Shane Bryson . Revised on 11 September 2023.

Tense communicates an event’s location in time. The different tenses are identified by their associated verb forms. There are three main verb tenses: past ,  present , and  future .

In English, each of these tenses can take four main aspects:  simple ,  perfect ,  continuous  (also known as  progressive ), and  perfect continuous . The perfect aspect is formed using the verb  to have , while the continuous aspect is formed using the verb  to be .

In academic writing , the most commonly used tenses are the  present simple , the  past simple , and the  present perfect .

Tenses and their functions, when to use the present simple, when to use the past simple, when to use the present perfect, when to use other tenses.

The table below gives an overview of some of the basic functions of tenses and aspects. Tenses locate an event in time, while aspects communicate durations and relationships between events that happen at different times.

It can be difficult to pick the right verb tenses and use them consistently. If you struggle with verb tenses in your thesis or dissertation , you could consider using a thesis proofreading service .

Correct my document today

The present simple is the most commonly used tense in academic writing, so if in doubt, this should be your default choice of tense. There are two main situations where you always need to use the present tense.

Describing facts, generalisations, and explanations

Facts that are always true do not need to be located in a specific time, so they are stated in the present simple. You might state these types of facts when giving background information in your introduction .

• The Eiffel tower  is in Paris.
• Light  travels faster than sound.

Similarly, theories and generalisations based on facts are expressed in the present simple.

• Average income differs by race and gender.
• Older people express less concern about the environment than younger people.

Explanations of terms, theories, and ideas should also be written in the present simple.

• Photosynthesis  refers to  the process by which plants  convert sunlight into chemical energy.
• According to Piketty (2013), inequality grows over time in capitalist economies.

Describing the content of a text

Things that happen within the space of a text should be treated similarly to facts and generalisations.

This applies to fictional narratives in books, films, plays, etc. Use the present simple to describe the events or actions that are your main focus; other tenses can be used to mark different times within the text itself.

• In the first novel, Harry learns he is a wizard and travels  to Hogwarts for the first time, finally escaping the constraints of the family that raised him.

The events in the first part of the sentence are the writer’s main focus, so they are described in the present tense. The second part uses the past tense to add extra information about something that happened prior to those events within the book.

When discussing and analyzing nonfiction, similarly, use the present simple to describe what the author does within the pages of the text ( argues , explains , demonstrates , etc).

• In The History of Sexuality , Foucault asserts that sexual identity is a modern invention.
• Paglia (1993) critiques Foucault’s theory.

This rule also applies when you are describing what you do in your own text. When summarising the research in your abstract , describing your objectives, or giving an overview of the  dissertation structure in your introduction, the present simple is the best choice of tense.

• This research  aims to synthesise the two theories.
• Chapter 3 explains  the methodology and discusses ethical issues.
• The paper  concludes with recommendations for further research.

The past simple should be used to describe completed actions and events, including steps in the research process and historical background information.

Reporting research steps

Whether you are referring to your own research or someone else’s, use the past simple to report specific steps in the research process that have been completed.

• Olden (2017) recruited 17 participants for the study.
• We transcribed and coded the interviews before analyzing the results.

The past simple is also the most appropriate choice for reporting the results of your research.

• All of the focus group participants agreed  that the new version  was an improvement.
• We  found a positive correlation between the variables, but it  was not as strong as we  hypothesised .

Describing historical events

Background information about events that took place in the past should also be described in the past simple tense.

• James Joyce  pioneered the modernist use of stream of consciousness.
• Donald Trump’s election in 2016  contradicted the predictions of commentators.

The present perfect is used mainly to describe past research that took place over an unspecified time period. You can also use it to create a connection between the findings of past research and your own work.

Summarising previous work

When summarising a whole body of research or describing the history of an ongoing debate, use the present perfect.

• Many researchers  have investigated the effects of poverty on health.
• Studies  have shown a link between cancer and red meat consumption.
• Identity politics has been a topic of heated debate since the 1960s.
• The problem of free will  has vexed philosophers for centuries.

Similarly, when mentioning research that took place over an unspecified time period in the past (as opposed to a specific step or outcome of that research), use the present perfect instead of the past tense.

• Green et al.  have conducted extensive research on the ecological effects of wolf reintroduction.

Emphasising the present relevance of previous work

When describing the outcomes of past research with verbs like fi nd ,  discover or demonstrate , you can use either the past simple or the present perfect.

The present perfect is a good choice to emphasise the continuing relevance of a piece of research and its consequences for your own work. It implies that the current research will build on, follow from, or respond to what previous researchers have done.

• Smith (2015) has found that younger drivers are involved in more traffic accidents than older drivers, but more research is required to make effective policy recommendations.
• As Monbiot (2013)  has shown , ecological change is closely linked to social and political processes.

Note, however, that the facts and generalisations that emerge from past research are reported in the present simple.

While the above are the most commonly used tenses in academic writing, there are many cases where you’ll use other tenses to make distinctions between times.

Future simple

The future simple is used for making predictions or stating intentions. You can use it in a research proposal  to describe what you intend to do.

It is also sometimes used for making predictions and stating hypotheses . Take care, though, to avoid making statements about the future that imply a high level of certainty. It’s often a better choice to use other verbs like  expect ,  predict,  and  assume to make more cautious statements.

• There  will be a strong positive correlation.
• We  expect  to find a strong positive correlation.
• H1  predicts a strong positive correlation.

Similarly, when discussing the future implications of your research, rather than making statements with will,  try to use other verbs or modal verbs that imply possibility ( can ,  could ,  may ,  might ).

• These findings  will influence  future approaches to the topic.
• These findings  could influence future approaches to the topic.

Present, past, and future continuous

The continuous aspect is not commonly used in academic writing. It tends to convey an informal tone, and in most cases, the present simple or present perfect is a better choice.

• Some scholars are suggesting that mainstream economic paradigms are no longer adequate.
• Some scholars suggest   that mainstream economic paradigms are no longer adequate.
• Some scholars have suggested   that mainstream economic paradigms are no longer adequate.

However, in certain types of academic writing, such as literary and historical studies, the continuous aspect might be used in narrative descriptions or accounts of past events. It is often useful for positioning events in relation to one another.

• While Harry is traveling to Hogwarts for the first time, he meets many of the characters who will become central to the narrative.
• The country was still recovering from the recession when Donald Trump was elected.

Past perfect

Similarly, the past perfect is not commonly used, except in disciplines that require making fine distinctions between different points in the past or different points in a narrative’s plot.

The “no second-person” myth

Many writers believe the “no second-person” myth, which is that there is an APA Style guideline against using second-person pronouns such as “you” or “your.” On the contrary, you can use second-person pronouns in APA Style writing.

The “no first-person” myth

Whether expressing your own views or actions or the views or actions of yourself and fellow authors, use the pronouns “I” and “we.”

Grammar: Verb Tenses

Most common verb tenses in academic writing.

According to corpus research, in academic writing, the three tenses used the most often are the simple present , the simple past , and the present perfect (Biber et al., 1999; Caplan, 2012). The next most common tense for capstone writers is the future ; the doctoral study/dissertation proposal at Walden is written in this tense for a study that will be conducted in the future.

Biber, D., Johansson, S., Leech, G., Conrad, S., & Finegan, E. (1999). Longman grammar of written and spoken English . Pearson. https://doi.org/10.1162/089120101300346831

Caplan, N. A. (2012). Grammar choices for graduate and professional writers . University of Michigan Press.

Simple present: Use the simple present to describe a general truth or a habitual action. This tense indicates that the statement is generally true in the past, present, and future.

• Example: The hospital admits patients whether or not they have proof of insurance.

Simple past : Use the simple past tense to describe a completed action that took place at a specific point in the past (e.g., last year, 1 hour ago, last Sunday). In the example below, the specific point of time in the past is 1998.

• Example: Zimbardo (1998) researched many aspects of social psychology.

Present perfect: Use the present perfect to indicate an action that occurred at a nonspecific time in the past. This action has relevance in the present. The present perfect is also sometimes used to introduce background information in a paragraph. After the first sentence, the tense shifts to the simple past.

• Example: Numerous researchers have used this method.
• Example: Many researchers have studied how small business owners can be successful beyond the initial few years in business. They found common themes among the small business owners.

Future: Use the future to describe an action that will take place at a particular point in the future (at Walden, this is used especially when writing a proposal for a doctoral capstone study).

• Example: I will conduct semistructured interviews.

Keep in mind that verb tenses should be adjusted after the proposal after the research has been completed. See this blog post about Revising the Proposal for the Final Capstone Document for more information.

APA Style Guidelines on Verb Tense

APA calls for consistency and accuracy in verb tense usage (see APA 7, Section 4.12 and Table 4.1). In other words, avoid unnecessary shifts in verb tense within a paragraph or in adjacent paragraphs to help ensure smooth expression.

• Use the past tense (e.g., researchers presented ) or the present perfect (e.g., researchers have presented ) for the literature review and the description of the procedure if discussing past events.
• Use the past tense to describe the results (e.g., test scores improved significantly).
• Use the present tense to discuss implications of the results and present conclusions (e.g., the results of the study show …).

When explaining what an author or researcher wrote or did, use the past tense.

• Patterson (2012) presented, found, stated, discovered…

However, there can be a shift to the present tense if the research findings still hold true:

• King (2010) found  that revising a document three times improves the final grade.
• Smith (2016) discovered that the treatment is effective.

Verb Tense Guidelines When Referring to the Document Itself

To preview what is coming in the document or to explain what is happening at that moment in the document, use the present or future tense:

• In this study, I will describe …
• In this study, I describe …
• In the next chapter, I will discuss …
• In the next chapter, I discuss …

To refer back to information already covered, such as summaries of discussions that have already taken place or conclusions to chapters/sections, use the past tense:

• Chapter 1 contained my original discussion of the research questions.
• In summary, in this section, I presented information on…

Simple Past Versus the Present Perfect

Rules for the use of the present perfect differ slightly in British and American English. Researchers have also found that among American English writers, sometimes individual preferences dictate whether the simple past or the present perfect is used. In other words, one American English writer may choose the simple past in a place where another American English writer may choose the present perfect.

Keep in mind, however, that the simple past is used for a completed action.  It often is used with signal words or phrases such as "yesterday," "last week," "1 year ago," or "in 2015" to indicate the specific time in the past when the action took place.

• I went to China in 2010 .
• He completed the employee performance reviews last month .

The present perfect focuses more on an action that occurred without focusing on the specific time it happened. Note that the specific time is not given, just that the action has occurred.

• I have travelled to China.

The present perfect focuses more on the result of the action.

• He has completed the employee performance reviews.

The present perfect is often used with signal words such as "since," "already," "just," "until now," "(not) yet," "so far," "ever," "lately," or "recently."

• I have already travelled to China.
• He has recently completed the employee performance reviews.
• Researchers have used this method since it was developed.

What tense to use when writing a thesis?

I am well aware of the fact that there are a number of questions that talk about tenses in research, but I still have not found exactly what I am after.

Basically my question is this, in a Master dissertation, should the tense be the same throughout the entire text? Or is it acceptable (or even required) to use different tenses in different structures?

Assuming the following structure, if you believe that there should be separate tenses, would the suggestions in brackets be correct?

• Title ( Present )
• Abstract ( Imperfect Past )
• Introduction ( Present + Future )
• Methodology ( Past Perfect, Present, Future or Mix? )
• Results ( Past Perfect )
• Discussion ( Present* )
• Conclusion ( Mix?, conditional present )

*Would the choice of any present tense put all preceding sections in a past tense?

Looking at that structure I find it hard to see that only one tense should be adopted throughout the entire text.

• I was about to say "The correct tense for the correct sections" but I see you are already thinking in terms of sections. Good question. It might be interesting to run corpus linguistics on this to find out. –  Frames Catherine White Commented Jul 4, 2017 at 15:39
• 1 I would use the past only for discussion of prior work. –  gerrit Commented Jul 4, 2017 at 17:09
• @gerrit: In papers involving experiments, the experiments are typically described in the past tense. –  Peter Shor Commented Jul 4, 2017 at 18:51
• @PeterShor Maybe so. That makes me a minority. I don't destroy my instruments after use so when I describe them, I do so in the present tense. I might use them again! Consistency is most important, however. –  gerrit Commented Jul 4, 2017 at 18:57
• @gerrit: I can see writing "The apparatus consists of ..." , but do you mean you would also write "500 observations are taken for each value of the electric field" ? –  Peter Shor Commented Jul 4, 2017 at 19:27

The answer to this question varies across disciplines. Your dissertation presumably falls within some academic discipline. Look at other papers in the same discipline, and see what tenses they use. For example, unlike your suggestion, in math papers the abstract is usually present tense.

If some of the premier journals in your discipline have a style guide, look at these style guides and see what they say.

The journal Nature , in which the majority of articles are in the sciences, has the following suggestions for verb tense (I've left out a few of their examples):

Past tense Work done We collected blood samples from . . . Consequently, astronomers decided to rename . . . Work reported Jankowsky reported a similar growth rate . . . In 2009, Chu published an alternative method to . . . Observations The mice in Group A developed, on average, twice as much . . . The conversion rate was close to 95% . . . Present tense General truths Microbes in the human gut have a profound influence on . . . The Reynolds number provides a measure of . . . Atemporal facts This paper presents the results of . . . Section 3.1 explains the difference between . . . Behbood's 1969 paper provides a framework for . . . Future tense Perspectives In a follow-up experiment, we will study the role of . . . The influence of temperature will be the object of future research . . .

• "We collected blood samples from . . ." That's strange. I thought they want you to avoid I and We? "Blood samples were collected from..." sounds much more like a nature paper. –  user64845 Commented Jul 4, 2017 at 22:01
• @DSVA: There has been a rethinking of the tradition of never using we or I in scientific papers. While some journals still maintain this rule, many welcome use of the first person plural. Another quote from that same link: 'As a second argument against a systematic preference for the passive voice, readers sometimes need people to be mentioned. A sentence such as "The temperature is believed to be the cause for . . . " is ambiguous. Readers will want to know who believes this — the authors of the paper, or the scientific community as a whole? ' (continued ...) –  Peter Shor Commented Jul 4, 2017 at 23:55
• 'To clarify the sentence, use the active voice and set the appropriate people as the subject, in either the third or the first person, as in the examples below. Biologists believe the temperature to be . . . Keustermans et al. (1997) believe the temperature to be . . . The authors believe the temperature to be . . . We believe the temperature to be . . . ' –  Peter Shor Commented Jul 4, 2017 at 23:55
• And let me modify the Nature suggestions. I have the impression that work done and observations are usually past tense, but work reported is often present perfect tense — Jankowsky has reported a similar growth rate ... Of course, if you mention a year with work reported, then for grammatical reasons it has to be past tense. –  Peter Shor Commented Aug 27, 2017 at 20:16

How Can You Decide on Tense Usage in Your Dissertation?

The corpus research suggests that the most often used tenses in academic writing are the simple present, the simple past, and the present perfect. Then, what comes next is the future tense.

Which tenses are most common in academic writing?

The corpus research suggests that the most often used tenses in academic writing are the simple present tense, the simple past tense, and the present perfect tense. Then, what comes next is the future tense.

Simple present tense: You can use the simple present to define a general truth or a habitual action. This tense demonstrates that what you state is usually true in the past, present, and future.

Example:  Water generally boils at 100C.

Simple past : You may employ the simple past tense to call a completed action that occurred at a specific point in the past (e.g., last month, one hour ago, last Sunday). The specific point of time is 2019 in the following example.

Example:  The first known COVID outbreak started in Wuhan, Hubei, China, in November 2019.

Present perfect tense: The present perfect indicates an action occurring at a nonspecific time or repeatedly in the past. However, this action has a close connection with the present time. The present perfect tense may introduce background information in a paragraph, reinforcing the main idea mentioned there. Following the first sentence, switching to the simple past is possible.

Example:  Many scientists  have employed  this method.

Example:  Many researchers  have investigated  how a small firm can succeed after its poor start. They gradually learned what is essential in the market.

Future tense:  You may use the future tense to describe an action that will occur at a particular point in the future (It is imperative when writing a research, grant, or dissertation proposal).

Example:  I  will conduct  the ANOVA procedure in my study’s statistical part.

APA guidelines concerning verb tenses

In its last published guideline, APA accentuated the consistency and accuracy in tense verb usage (APA 7, Section 4.12 and Table 4.1). It suggests that you must avoid unnecessary shifts in verb tense within a paragraph or adjacent paragraphs. This avoidance helps secure smooth expression and improves readability. It would be best if you used the past tense (e.g., scientists  posed ) or the present perfect (e.g., researchers  have concluded ) for the literature review . Thus, you must present the procedure description if you discuss past events. Nonetheless, it would help if you resorted to the past tense to describe the results (for example, ANOVA results revealed that the treatment improved food's shelf-life substantially). In discussing the implications of the results and present conclusions, you must use the present tense (i.e., our results suggest that alcohol consumption increases the accident incidence rate). 

When you need to explain what an author or scientist stated or did, you must use the past tense.

Milliken (2012)  reported, revealed, stated, found that…..…

Nevertheless, you can shift to the present tense if your research findings can be generalized or held in general:

Hunt (2010)  revealed  that revising a manuscript  improves  its chance of acceptance.

Kropf (2016)  discovered  that color  is  an essential trait of fresh meat.

Which tense should I use referring to my document (thesis, dissertation, research proposal, etc.)

If you wish to preview what is ahead in your text or elaborate on what is happening at that moment in your document, you must use either the present or future tense.

In this research, I  will specify …

In this research, I  specify …

In the last chapter, I  will elaborate on …

In the last chapter, I  elaborate on …

You can also refer back to already presented information, such as a synopsis of discussions that have already occurred or conclusions to your chapters or sections. Then, the tense you have to use is the past tense:

Chapter 1  contained  the literature review.

In closing, in this section, I  posed  information on…

Should I use simple past tense or present perfect tense?

British and American English have slightly varying rules for using the present perfect tense. Scientists have also reported that individual preferences may dictate the usage of the simple past or the present perfect tense in American English. Put differently, an American English writer may opt for the simple past on specific occasions, whereas another American English writer may prefer the present perfect without apparent reasons.

However, you must note that the simple past tense denotes a completed action. Therefore, it usually employs signal words or phrases, including "yesterday," "last year," "a week ago," or "in 2020," to designate the specific time in the past when the action occurred.

I  went  to Greece  in 2011 .

He  finished  the team member performance report  last week .

The present perfect concentrates more on the action without accentuating the specific time it occurred. Note that the action has occurred even though the specific time is unavailable.

I  have seen this movie three times .

The present perfect also concentrates more on the result of the action.

He  has finished  reviewing the manuscript.

You should be able to understand the usage of the present perfect with some signal words such as "since," "already," "just," "until now," "(not) yet," "so far," "ever," "lately," or "recently."

I  have  already  finished  the book on the Turkish economy.

Researchers  have used  this term  since  it was coined.

A theoretical framework primarily supports the idea of a research study. It bears all the theories that prove the essence and importance of any research. In a nutshell, it is developed to explain the research and comprehend its circumstances. It may involve all the theory-based logic behind the importance and existence of your research in academics. This step-by-step guide discusses how to build a theoretical framework for a dissertation.

Writing a thesis or dissertation is considered the final phase of your Ph.D. journey. You must cover three to five years of study and research into your thesis. A doctoral thesis or dissertation is a long essay of knowledge and research on a specific niche that poses interesting questions and answers with your reasoning. Ph.D. candidates should carefully choose the study topic according to their expertise. This article explains how to write an impeccable Ph.D. thesis for outstanding results in 6 helpful steps.

What you aim to address in your dissertation relates to a research problem. It is primarily a unique issue, challenge, paradox, or breach in the current literature. It would be best if you searched for practical problems and targeted addressing them to expand the actual knowledge.

The tense debate

Last week my friend and PhD student @tokenlefty emailed me to ask:

“When writing literature reviews, does one use past tense or present tense?  ie: Sorensen examined the potential for .. or: Sorensen examines the potential for

I wrote back:

“I prefer present tense because it implies an active conversation. Unless the author is dead, mc dead dead and everyone knows it. Even then there’s dead and Really Dead.”

Which didn’t make much sense when I read it back to myself. In my defense I was kind of busy and @tokenlefty is accustomed to getting cryptic emails from me. Then I had a thought – is this just the way I do it? Is there a ‘correct’ way to do tense that I was not aware of? As I looked into the issue, it was surprisingly complex and I decided it needed a post on its own.

The usual advice it to pick a tense and stick to it throughout your thesis. I like present tense – most of the time. For me the use of present tense implies that a scholarly conversation is going on Right Now, and that you are commenting on it (much like a cricket game). The Scholarly Conversation may have been going on for some decades – but that is still Right Now in an academic sense. Besides I have read many times that using present tense is one way to have an ‘active’ voice in your writing – which makes your thesis an easier read.

I do ‘break the rules’ and use past tense alongside present tense, usually for rhetorical purpose . For instance, like many other disciplines, the research field I work in (education) has a heritage of ideas.  I will still routinely use present tense to refer to people who ‘grandfathered’ the ideas which I am using (sorry for the gendering there, but unfortunately they are all men). I learned this from my colleague and philosopher Dr Robyn Barnacle , who argues that although people die, their ideas live on. Following this logic I  use past tense to talk about dead ideas – even if the people who wrote about them are still living. There is however the ‘dead mc dead dead’ category, which I reserve for people like Socrates and Aristotle: some of their ideas are so fundamental they have never died, but to refer to them in present tense would be, well – kind of weird.

But. Should I be recommending this approach to someone in an entirely different field to me? As the Explorations in Style blog said in a post about using resources this week, we should be careful of any kind of ‘universalizing’ advice when it comes to doing a thesis. I agree with this wholeheartedly; disciplinary context matters. As Howard Becker pointed out: we all have an ‘academic accent’ in our writing which marks us as members of a certain tribe. Learning to develop this accent is part of the reason for doing a PhD in the first place.

I still didn’t have an answer for this blog, which tries to cater to all disciplines. So I tried to get clarity by consulting with the oracles , i.e.: all my ‘go to’ texts on writing a thesis which you can see in the photo. I’m sorry to say, most of them let me down. In “Helping Doctoral students to Write” by Kamler and Thomson there is an excellent discussion on active voice and passive voice (chapter seven). This seemed, from close reading, to back up what I am saying. But again, this is written for a social science / educational audience.

Facing a dead end, I emailed my back up oracle, and fellow research education nerd , Dr Judy Maxwell at the Study and Learning Centre here at RMIT, who spends most of her days teaching scientists about grammar. Judy confirmed that the debate about which tense to use is a hot topic amongst research students and confirmed that there isn’t one authoritative text on it. She noted that there is “a general feeling among science/engineering students that the past tense is always used”.

Like me, Judy doesn’t like the use of past tense, but for a different reason. She pointed out that there’s the potential for ambiguity: does the person you’ re citing still think the same way , or has she/he moved on? Judy tells me, however, that when she presents this point of view to science/engineering researchers they don’t see it as a problem, she thinks this stems from:

“… the way the hard/technical sciences generally talk about the literature – they’re usually more interested in the actual research rather than what was found, which is generally the opposite of social sciences, where what was found, and who found it, is more important. This is probably why author/date systems such as APA and Harvard and more author-prominent citations are used in these areas, compared to Vancouver or footnotes and information-prominent citations are used in hard/physical sciences.”

Usually Judy’s answer for questions about writing style (and mine) is to refer students to journal articles and theses in their discipline. But, as Judy and I talked, we wondered if this is good advice. We don’t want to   promote replicating present practice  if the practice itself is questionable . Just like the Greeks still built stone temples like they were wood temples , we can hang onto ways of doing things long beyond their use by date: especially, I would argue, in academia.

As so often happens, I am left with more questions than answers (but you guys don’t read this blog for simplistic answers right?!). Clearly there’s the potential for choice here; maybe talking about it more will help you make a decision. So how do you ‘do tense’ in your literature review and why? Have you argued with your supervisor about it? Do you think the argument that “everyone does it this way” is a good enough reason to keep doing it that way?

Forming the Future Tenses of English Verbs for Theses and Dissertations

Forming the Future Tenses of English Verbs for Theses and Dissertations Many thesis and dissertation candidates, especially those whose native language is not English, find the conjugation of English verbs somewhat tricky. For this reason, I have written a few posts on conjugating the tenses of English verbs for postgraduate students, with this article tackling the future forms. Please note that in the examples of correct usage I provide below, the verb forms I am discussing appear in uppercase letters for clarity, not because such capitals should be used in scholarly prose. The future simple is formed by using the auxiliary verb ‘will’ followed by the main verb, as in ‘He WILL READ my book,’ ‘You WILL WORK at the library’ and ‘They WILL CONDUCT advanced research.’ For a negative construction, ‘not’ should be inserted between the auxiliary and the main verb, as in ‘We WILL not READ that book’ or ‘I WILL not CONDUCT advanced research.’ A question is formed when the positions of the subject and the auxiliary verb are exchanged: ‘WILL you WORK at the library?’ and ‘WILL he READ my book too?’ The future simple describes action that will occur in the future and can also be used for prediction, as in ‘It WILL RAIN tonight.’ The verb ‘to think’ is often used along with the simple future, so ‘I think it WILL RAIN tonight’ is an alternative form of expression. PhD Thesis Editing Services The future continuous or future progressive tense is constructed by using the auxiliary verbs ‘will’ and ‘be’ followed by the present participle of the main verb. ‘He WILL BE READING my book tomorrow,’ ‘You WILL BE ATTENDING the conference next week’ and ‘They WILL BE SLEEPING by then’ are good examples. The word ‘not’ is inserted between ‘will’ and ‘be’ to form a negative statement, whereas the subject changes places with the word ‘will’ when a question is intended. ‘We WILL not BE ATTENDING the conference’ demonstrates the first, and ‘WILL she BE VISITING the library?’ shows the second. The future continuous is used to describe something that will be happening at a given moment or point in the future – a moment at which the action will have started but not finished – and even when the time is not specifically mentioned, the reader generally understands what time is intended. The future perfect is formed with the auxiliary verbs ‘will’ and ‘have’ along with the past participle of the main verb. ‘He WILL HAVE READ my book by then,’ ‘You WILL HAVE VISITED the library before lunch’ and ‘They WILL HAVE FINISHED their paper first’ are sound examples. For a negative construction, the word ‘not’ should be inserted between ‘will’ and ‘have,’ as it is in ‘We WILL not HAVE DRIVEN to the library before noon.’ A question is formed by exchanging the positions of the subject and the auxiliary verb ‘will’: ‘WILL she HAVE FINISHED her thesis before the deadline?’ The future perfect reports action in the future that occurs before another action in the future; it is therefore ‘perfect’ in that it expresses the past from the perspective of the future. The future perfect continuous, also referred to as the future perfect progressive, is constructed by using no less than three auxiliary verbs – ‘will,’ ‘have’ and ‘be’ – followed by the present participle of the main verb. Examples include ‘He WILL HAVE BEEN READING the book for days by then,’ ‘You WILL HAVE BEEN FLYING all night to arrive on time’ and ‘We WILL HAVE BEEN SITTING for hours when we arrive.’ A negative sentence includes the word ‘not’ between ‘will’ and ‘have,’ as in ‘They WILL not HAVE BEEN READING for days,’ and a question switches the positions of the subject and the auxiliary verb ‘will,’ as is the case in ‘WILL she HAVE BEEN FLYING all night?’ The future perfect continuous is similar to the future perfect, but the actions it describes tend to be longer or extended up to a specific point or moment in the future, with the action beginning in the past, present or future, but always ceasing in the future. PhD Thesis Editing Services As a final note, do be aware that the auxiliary verb ‘shall’ is sometimes used instead of ‘will’ in these future constructions, especially with ‘I’ or ‘we’ as the subject. ‘I SHALL READ that book,’ ‘We SHALL BE VISITING the library tomorrow,’ ‘I SHALL HAVE FINISHED the book by tonight’ and ‘We SHALL HAVE BEEN SITTING for hours when we arrive’ are therefore acceptable alternative constructions.

Why Is Proofreading Important?

To improve the quality of papers.

Effective proofreading is absolutely vital to the production of high-quality scholarly and professional documents. When done carefully, correctly and thoroughly, proofreading can make the difference between writing that communicates successfully with its intended readers and writing that does not. No author creates a perfect text without reviewing, reflecting on and revising what he or she has written, and proofreading is an extremely important part of this process.

Whether you are discussing past research, presenting current findings, or speculating on future implications, this guide will serve as your invaluable resource for selecting the appropriate verb tense throughout your academic masterpiece.

• Common tenses
• Literature reviews
• Discussion & Conclusion
• Recommendations

The most common tenses used in Academic Writing include:

In the literature review you should:

• Summarise and synthesise the most important ideas from a range of relevant documents on the topic.
• Identify any problems with the literature, such as gaps or limitations.

Thus, the verb tenses commonly used in literature review section include:

Reporting Verbs

When you include a reference in your text – whether it's a quote, paraphrase or summary – you will probably use a reporting verb.  Be careful, as they can have different meanings, even if some of the differences in meaning are quite subtle.  Reporting verbs can show your opinion of others’ ideas: 

• a belief that the literature is correct ( stronger position ). For example: If you write, ‘Smith (2023) discovered that . . . ‘, you are accepting their position.
• a neutral attitude towards the veracity of the literature (i.e. neither correct nor incorrect – neutral position ). For example: If you write, ‘Smith (2023) concludes that . . . ‘, you are adopting a neutral stance.
• a belief that the literature is incorrect ( weaker position ). For example: If you write, ‘Smith (2023) alleges that . . . ‘, you are viewing their work in a suspicious light, casting doubt on their opinion.

Tip: Use a range of reporting verbs and avoid using the same reporting verb over and over (e.g. state)    state)

Here is a list of common reporting verbs that you can use depending on their function and strength:

*You will often use the present simple with reporting verbs e.g. Evidence suggest that, however you will use other tenses also. 

For more examples of language used in literature reviews, have a look at the ‘Referring to Sources’ section of the Academic Phrasebank.  

Information in the methods section might include information about the instruments and information about the experimental procedure. Verb tenses commonly used in the method section include:

For more examples of language used in methods, have a look at the ‘Describing methods’ section of the Academic Phrasebank . 

Passive vs Active Voice

The passive voice is useful to switch the focus from who is doing something to what is being done (i.e., avoid personal language such as 'I' or 'We'). The “who” becomes less important than the “what”.

For example: Active Voice - I sorted the samples according to size.  

Passive Voice - The samples were sorted according to size.

• Using the passive voice sounds more formal and is used a lot in academic writing
• However, overusing the passive could make your writing seem 'flat' and uninteresting.
• Try to vary sentence structure and, where possible, avoid too many passive sentences in a row.
• Remember, the active voice may be preferable to draw attention to who has been carrying out the action. Sometimes it is important to show who is doing the action. You will have to use your judgement as best you can.

The results section commonly includes tables and figures. The writing around the figures and tables serves to introduce what they are and what conditions you obtained them under, as well as guiding the reader to understand the features in your results.  Verb tenses commonly used in the results section include:

Using tables and figures 

The description of tables and figures in academic written texts commonly includes two different elements: 

• Location or summary statement: identifies the table or figure and indicates the content
• Highlighting statement or statements: point out and describe the relevant or significant data

Dos and Don’ts of using tables and figures 

For more examples of language used in results sections, have a look at the ‘Reporting Results’ section of the Academic Phrasebank.  

In the discussion section you will compare your results with the previous literature and highlight the importance of your results. The conclusion is an opportunity to restate the aims or key questions and to summarise the key points raised in the results and discussion sections. Verb tenses commonly used in the discussion and conclusion sections include:

For more examples of language used in discussions and conclusions, have a look at the ‘Discussing Findings’ and ‘Writing Conclusions’ sections of the Academic Phrasebank.  

The conclusion section can also contain recommendations and implications for practice , or these can be placed in a separate section. This section discusses events that may happen in the future. However, no writer can make predictions with absolute certainty. To avoid or ‘soften’ the future tense you can use:

For more examples of language used for recommendations, have a look at the ‘Setting Out Recommendations for Practice or Policy’ in the ‘Writing Conclusions’ section of the Academic Phrasebank.

Hedging or cautious language

In academic writing, the use of hedging or cautious language is a common practice employed to acknowledge uncertainty, limitations, or alternative perspectives within a study. This cautious language is utilized to convey a balanced and objective approach, recognizing the complexity of research findings and the inherent uncertainties that exist. Hedging can be achieved through various linguistic strategies, such as using modal verbs (e.g., may, might, could), cautious adverbs (e.g., possibly, potentially), or phrases that indicate probability (e.g., it is likely that, there is evidence to suggest). By incorporating such expressions, academic writers signal their awareness of the potential limitations and provide a nuanced and accurate representation of the research, fostering intellectual humility and encouraging further investigation. The use of hedging or cautious language ensures that academic discourse is characterized by careful deliberation, integrity, and transparency.

For more examples of hedging or cautious language, have a look at "Using cautious language" section of the Academic Phrasebank. 

Journal of Suffolk Student Research

The Journal of Suffolk Student Research is an online academic journal, dedicated to the publication of high-quality undergraduate and postgraduate student research undertaken by University of Suffolk students. The journal will showcase the most outstanding student research undertaken at the University of Suffolk. It aims to promote and recognise this outstanding student research by offering valuable early experience of academic publishing and the peer review process.

Adherence to the correct tenses is essential in academic writing , directly impacting its conciseness, clarity, and readability. At times, deciding on the appropriate tense could be relatively perplexing, entailing a careful application of language rules . Yet, the situation is not as complex as it may initially seem. As indicated by Cambridge University Press, the majority of students will only need a handful of tenses to express their ideas effectively, once they grasp the associated language rules.

Tenses in a nutshell

Tenses are used to express when an action happens: in the past, present, or future. They convey the timing and duration of events in a clear and structured way.

Definition: Tenses

Tenses are grammatical constructs that express the time at which an action or event takes place. In English, verb tenses are used to indicate whether an action occurs in the past , present , or future . They also convey additional information about the action, such as whether it is ongoing, completed, or habitual. As mentioned before, they can be divided into three main categories, which each have four aspects or subcategories : simple, continuous (also known as progressive), perfect, and perfect continuous. These subdivisions allow for a nuanced expression of time and aspect, which enables both speakers and writers to convey the exact nature of an action.

The 12 tenses

There are a total of 12 time forms in English, each conveying details about the time and nature of the action. In this section, we will introduce you to all types and subtypes of tenses by dividing them into past, simple, and future. After this, we’ll provide you with a downloadable PDF document, that encompasses all time forms.

The present

The English language has four subcategories for the main category “present.” Each one will be explained below, along with numerous examples and how to form them.

• Present simple

Present continuous

Present perfect, present perfect continuous.

Present simple, or simple present, is used to describe everyday actions and general truths . It’s the most basic of the English tenses for English learners, as it is often formed with just the root verb with no additions. The only mistake one can make, is to forget the suffix “-s” or “-es,” which is added to the verb when the subject is in third-person singular .

• If the verb ends in – o , -ch , -sh , -th , -ss , -gh , or -z you add “-es.”
• If the verb ends in a consonant and -y , you drop the -y and add “-ies.”

Subject + infinitive (+ “s” or “es” for 3rd person singular)

• She writes a letter every day.
• They play soccer on weekends.
• He eats breakfast at 7 AM.

Present continuous, or present progressive, describes actions that are happening right now  or around the current time . For this tense, auxiliary verbs are needed.

• For singular first-person pronouns , you use “am.”
• For third-person personal pronouns , you use “is.”
• For plural personal pronouns , you use “are.”

Subject + am/is/are + verb+ing

• She is writing a letter now.
• They are playing soccer at the moment.
• He is eating breakfast right now.

Present perfect is used to describe actions that were completed at some point before now , often with relevance to the present . It is formed with the auxiliary verbs have/has and the past participle of the verb, which is the second past form . More information can be found in our article on present perfect , which includes common temporal adverbs used with this tense, and our article on verb conjugation . More specifically, present perfect is used to describe actions that:

• are ongoing, but started in the past
• were completed very recently
• were completed multiple times before and are likely to be completed again

Subject + have/has + past participle

• She has written three letters today.
• They have played soccer many times.
• He has eaten breakfast already.

Present perfect continuous, or present perfect progressive, describes actions that started in the past and are still ongoing or have recently stopped . It is often used to emphasize the duration of the activity. It is formed by using the auxiliary verb have/has, been, and the -ing form of the verb.

Subject + have/has been + verb+ing

• She has been writing letters all morning.
• They have been playing soccer for two hours.
• He has been eating breakfast since 7 AM.

The English language has four subcategories for the main category “past.” Each category will be explained, as well as several example sentences and how to form them.

• Past simple

Past continuous

• Past perfect

Past perfect continuous

Past simple, or simple past, is used to describe actions that were completed at a specific time in the past . When it comes to this tense, there are two types of verbs: regular verbs and irregular verbs. How to form them can be found in our detailed article on the past simple tense, as well as many exercises and a helpful PDF document encompassing them all for a quick overview.

Subject + past simple form

• She wrote a letter yesterday.
• They played soccer last weekend.
• He ate breakfast at 7 AM.

The past continuous, or past progressive, is commonly used to describe actions that were in progress and were completed at a specific time in the past . It is formed with the helping verb was/were and the -ing form of the verb.

Subject + was/were + verb+ing

• She was writing a letter when I called.
• They were playing soccer at 5 PM.
• He was eating breakfast at 7 AM.

Past perfect is used to describe actions that were completed before another action in the past occurred . It is formed with the helping verb “had” and the past participle form of the verb.

Subject + had + past participle

• She had written a letter before dinner.
• They had played soccer before it started raining.
• He had eaten breakfast before 8 AM.

The past perfect continuous, or past perfect progressive, is used to describe actions that were ongoing in the past until another past action occurred . The different between this tense and the past perfect tense, is that the former was ongoing, while the latter was a one-time occurrence.  The past perfect continuous is formed with the auxiliary verb “had” and “been”, along with the -ing form of the verb.

Subject + had been + verb+ing

• She had been writing letters for an hour before dinner.
• They had been playing soccer for an hour when it started raining.
• He had been eating breakfast for 30 minutes before 8 AM.

In English, there are four subcategories for the main category “future.” Each one will be explained, as well as numerous example sentences and how they’re formed.

Future simple

Future continuous, future perfect, future perfect continuous.

Future simple, or simple future, is used to describe actions that will happen at a specific time in the future . It is formed by using the modal verb “will” (or the modal verb “shall,” which is more formal and less commonly used with first-person pronouns) before the infinitive of the verb. If the action will happen in the near future, you can also use the present continuous tense instead.

While “shall” is less commonly used in modern English, it can often be seen in formal or legal writing, as it is used to make polite offers or suggestions and conveys a stronger sense of resiliency or inevitability .

Subject + will + infinitive

• She will write a letter tomorrow.
• They will play soccer next weekend.
• He will eat breakfast at 7 AM.

Future continuous, or future progressive, is used to describe actions that will be ongoing at a specific time in the future . It is formed by using the helping verbs “will/shall” with “be” and the -ing form of the verb. It is often used to show more certainty than the future simple tense.

Subject + will be + verb+ing

• She will be writing a letter at this time tomorrow.
• They will be playing soccer at 5 PM tomorrow.
• He will be eating breakfast at 7 AM tomorrow.

Future perfect is used to describe actions that will be completed before a specific future time . It is formed with “will have” and the past participle of the verb.

Subject + will have + past participle

• She will have written the letter by tomorrow.
• They will have played soccer by the time you arrive.
• He will have eaten breakfast by 7 AM.

Future perfect continuous, or future perfect progressive, is used to describe actions that will be ongoing until a specific future time . Although it’s a rare occurrence in everyday life, this tense is used to emphasize the duration.

Subject + will have been + verb+ing

• She will have been writing letters for two hours by the time you arrive.
• They will have been playing soccer for an hour when you arrive.
• He will have been eating breakfast for 30 minutes by 7:30 AM.

Below, we have created a PDF document that encompasses the information above along with exercises.

Conditionals

Conditionals are grammatical sentence structures used to discuss possible or hypothetical situations and their consequences . They are important for tenses because they rely on specific verb forms to indicate when the condition and its result take place. The four types of conditionals will be explained below along with examples.

Zero conditional

The zero conditional is used for general truths or scientific facts where the result is always true if the condition is met .

If + present simple, present simple

First conditional

The first conditional is used for real and possible situations in the future .

If + present simple, will + infinitive

Second conditional

The second conditional is used for hypothetical or unlikely situations in the present or future .

If + past simple, would + infinitive

Third conditional

The third conditional is used for hypothetical situations in the past that did not happen .

If + past perfect, would have + past participle

Common tenses in academic writing

Three tenses are most commonly used in academic writing: present simple, past simple, and present perfect. The following paragraph introduces the functions and includes numerous examples for each one.

The present simple

Often considered to be the most common tense, the present simple serves several functions:

• To emphasize the primary focus of the article.
• To reinforce what is presently known about a topic.
• To make general observations and statements.
• To reference previous papers as well as current tables and figures.
• This study highlights the effects of climate change.
• Research indicates that a gender pay gap exists.
• Scholars regard academic careers as the most lucrative way to earn more money.
• This chart presents the results from prior control groups.

The past simple

Let us now examine when the past simple can be used as well as some examples:

• Reporting findings from a previous study where the author is named.
• Discuss what methods and/or data were utilized.
• Highlighting the results of ongoing research.
• Emphasizing that an event occurred in the past.
• Smith et al. found that the initial results were spurious.
• Quantitative analyses were employed.
• Our team implemented a double-blind study.
• The subjects had to report back weekly.

The present perfect

Let’s finally discuss the present perfect tense, as well as when it is most often used.

• When introducing new subjects.
• Generally summarizing what has already taken place.
• Citing prior findings without mentioning other authors.
• Making connections between the past and the present.
• An impressive body of research has shown.
• Prior findings have been illustrated.
• Others have discovered.
• Previous research has indicated a relationship.

Tenses in a research paper

A research paper consists of various sections, such as the abstract or methodology , and each of these sections necessitates a distinct tense. The following sections state and explain which tense is used in which component.

Most experts agree that the present simple tense is best utilized within the abstract. This is a clear way to state facts and highlight the subsequent results.

• Depression correlates with weight gain.
• Research indicates that a relationship exists.

Introduction

Introductions are used to provide further information that is believed to be true. Thus, both present perfect and present simple tense should be used.

• Research has proven mutations protect plants from diseases.
• Our study shows that confirmation bias exists.

Theoretical framework

Theoretical frameworks are intended to reinforce an existing theory and why the issue in question exists. Therefore, the majority of the information should be addressed with present simple or present perfect .

• Present perfect : Prior research has uncovered …
• Present simple : The table below presents details…

Methodology & results

The methodology of the study and the results will always occur before a conclusion is reached. Therefore, it is best to employ the past simple tense. This tense ensures clarity when discussing completed actions.

• Our team established specific parameters…
• The subsequent studies correlated with…

A combination of past and present tense verbs can be used when presenting a conclusion (depending upon what is being discussed).

• Past simple : Our research indicated that…
• Present perfect : These results have proven that…
• Present simple : Ultimately, evidence indicates that…

Literature review

Literature reviews often use the past simple tense to explain previous findings, highlighting what has been discovered in the past.

• In his groundbreaking study, Smith et al. found that…
• Longitudinal study findings confirmed that…
• Exploratory research coincided with our ultimate findings.

What tenses are frequently seen within academic papers?

Three verb tenses represent the lion’s share of those utilized within an academic paper. The most common tenses are:

What are the 12 tense forms?

The 12 tense forms are: present simple, present continuous, present perfect, present perfect continuous, past simple, past continuous, past perfect, past perfect continuous, future simple, future continuous, future perfect, and future perfect continuous.

What are the 3 main types of tenses?

The three main types are: present, past, and future.

What is a tense example?

Simple present: She goes to college every week.

Simple past: She went to college last week.

Simple future: She will go to college next week.

Frequently asked questions

What tense should i write my results in.

Results are usually written in the past tense , because they are describing the outcome of completed actions.

Frequently asked questions: Dissertation

Dissertation word counts vary widely across different fields, institutions, and levels of education:

• An undergraduate dissertation is typically 8,000–15,000 words
• A master’s dissertation is typically 12,000–50,000 words
• A PhD thesis is typically book-length: 70,000–100,000 words

However, none of these are strict guidelines – your word count may be lower or higher than the numbers stated here. Always check the guidelines provided by your university to determine how long your own dissertation should be.

A dissertation prospectus or proposal describes what or who you plan to research for your dissertation. It delves into why, when, where, and how you will do your research, as well as helps you choose a type of research to pursue. You should also determine whether you plan to pursue qualitative or quantitative methods and what your research design will look like.

It should outline all of the decisions you have taken about your project, from your dissertation topic to your hypotheses and research objectives , ready to be approved by your supervisor or committee.

Note that some departments require a defense component, where you present your prospectus to your committee orally.

A thesis is typically written by students finishing up a bachelor’s or Master’s degree. Some educational institutions, particularly in the liberal arts, have mandatory theses, but they are often not mandatory to graduate from bachelor’s degrees. It is more common for a thesis to be a graduation requirement from a Master’s degree.

Even if not mandatory, you may want to consider writing a thesis if you:

• Plan to attend graduate school soon
• Have a particular topic you’d like to study more in-depth
• Are considering a career in research
• Would like a capstone experience to tie up your academic experience

The conclusion of your thesis or dissertation should include the following:

• A restatement of your research question
• A summary of your key arguments and/or results
• A short discussion of the implications of your research

The conclusion of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

For a stronger dissertation conclusion , avoid including:

• Important evidence or analysis that wasn’t mentioned in the discussion section and results section
• Generic concluding phrases (e.g. “In conclusion …”)
• Weak statements that undermine your argument (e.g., “There are good points on both sides of this issue.”)

Your conclusion should leave the reader with a strong, decisive impression of your work.

While it may be tempting to present new arguments or evidence in your thesis or disseration conclusion , especially if you have a particularly striking argument you’d like to finish your analysis with, you shouldn’t. Theses and dissertations follow a more formal structure than this.

All your findings and arguments should be presented in the body of the text (more specifically in the discussion section and results section .) The conclusion is meant to summarize and reflect on the evidence and arguments you have already presented, not introduce new ones.

A theoretical framework can sometimes be integrated into a  literature review chapter , but it can also be included as its own chapter or section in your dissertation . As a rule of thumb, if your research involves dealing with a lot of complex theories, it’s a good idea to include a separate theoretical framework chapter.

A literature review and a theoretical framework are not the same thing and cannot be used interchangeably. While a theoretical framework describes the theoretical underpinnings of your work, a literature review critically evaluates existing research relating to your topic. You’ll likely need both in your dissertation .

While a theoretical framework describes the theoretical underpinnings of your work based on existing research, a conceptual framework allows you to draw your own conclusions, mapping out the variables you may use in your study and the interplay between them.

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organize your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation , such as:

• Your anticipated title
• Your abstract
• Your chapters (sometimes subdivided into further topics like literature review , research methods , avenues for future research, etc.)

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

In most styles, the title page is used purely to provide information and doesn’t include any images. Ask your supervisor if you are allowed to include an image on the title page before doing so. If you do decide to include one, make sure to check whether you need permission from the creator of the image.

Include a note directly beneath the image acknowledging where it comes from, beginning with the word “ Note .” (italicized and followed by a period). Include a citation and copyright attribution . Don’t title, number, or label the image as a figure , since it doesn’t appear in your main text.

Definitional terms often fall into the category of common knowledge , meaning that they don’t necessarily have to be cited. This guidance can apply to your thesis or dissertation glossary as well.

However, if you’d prefer to cite your sources , you can follow guidance for citing dictionary entries in MLA or APA style for your glossary.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. In contrast, an index is a list of the contents of your work organized by page number.

The title page of your thesis or dissertation goes first, before all other content or lists that you may choose to include.

The title page of your thesis or dissertation should include your name, department, institution, degree program, and submission date.

Glossaries are not mandatory, but if you use a lot of technical or field-specific terms, it may improve readability to add one to your thesis or dissertation. Your educational institution may also require them, so be sure to check their specific guidelines.

A glossary or “glossary of terms” is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. Your glossary only needs to include terms that your reader may not be familiar with, and is intended to enhance their understanding of your work.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. In contrast, dictionaries are more general collections of words.

An abbreviation is a shortened version of an existing word, such as Dr. for Doctor. In contrast, an acronym uses the first letter of each word to create a wholly new word, such as UNESCO (an acronym for the United Nations Educational, Scientific and Cultural Organization).

As a rule of thumb, write the explanation in full the first time you use an acronym or abbreviation. You can then proceed with the shortened version. However, if the abbreviation is very common (like PC, USA, or DNA), then you can use the abbreviated version from the get-go.

Be sure to add each abbreviation in your list of abbreviations !

If you only used a few abbreviations in your thesis or dissertation , you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimizing confusion about abbreviations unfamiliar to your reader.

A list of abbreviations is a list of all the abbreviations that you used in your thesis or dissertation. It should appear at the beginning of your document, with items in alphabetical order, just after your table of contents .

Your list of tables and figures should go directly after your table of contents in your thesis or dissertation.

Lists of figures and tables are often not required, and aren’t particularly common. They specifically aren’t required for APA-Style, though you should be careful to follow their other guidelines for figures and tables .

If you have many figures and tables in your thesis or dissertation, include one may help you stay organized. Your educational institution may require them, so be sure to check their guidelines.

A list of figures and tables compiles all of the figures and tables that you used in your thesis or dissertation and displays them with the page number where they can be found.

The table of contents in a thesis or dissertation always goes between your abstract and your introduction .

You may acknowledge God in your dissertation acknowledgements , but be sure to follow academic convention by also thanking the members of academia, as well as family, colleagues, and friends who helped you.

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .  

In a thesis or dissertation, the discussion is an in-depth exploration of the results, going into detail about the meaning of your findings and citing relevant sources to put them in context.

The conclusion is more shorter and more general: it concisely answers your main research question and makes recommendations based on your overall findings.

In the discussion , you explore the meaning and relevance of your research results , explaining how they fit with existing research and theory. Discuss:

• Your  interpretations : what do the results tell us?
• The  implications : why do the results matter?
• The  limitation s : what can’t the results tell us?

The results chapter or section simply and objectively reports what you found, without speculating on why you found these results. The discussion interprets the meaning of the results, puts them in context, and explains why they matter.

In qualitative research , results and discussion are sometimes combined. But in quantitative research , it’s considered important to separate the objective results from your interpretation of them.

The results chapter of a thesis or dissertation presents your research results concisely and objectively.

In quantitative research , for each question or hypothesis , state:

• The type of analysis used
• Relevant results in the form of descriptive and inferential statistics
• Whether or not the alternative hypothesis was supported

In qualitative research , for each question or theme, describe:

• Recurring patterns
• Significant or representative individual responses
• Relevant quotations from the data

Don’t interpret or speculate in the results chapter.

To automatically insert a table of contents in Microsoft Word, follow these steps:

• Apply heading styles throughout the document.
• In the references section in the ribbon, locate the Table of Contents group.
• Click the arrow next to the Table of Contents icon and select Custom Table of Contents.
• Select which levels of headings you would like to include in the table of contents.

Make sure to update your table of contents if you move text or change headings. To update, simply right click and select Update Field.

All level 1 and 2 headings should be included in your table of contents . That means the titles of your chapters and the main sections within them.

The contents should also include all appendices and the lists of tables and figures, if applicable, as well as your reference list .

Do not include the acknowledgements or abstract in the table of contents.

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

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.

In a thesis or dissertation, the acknowledgements should usually be no longer than one page. There is no minimum length.

The acknowledgements are generally included at the very beginning of your thesis , directly after the title page and before the abstract .

Yes, it’s important to thank your supervisor(s) in the acknowledgements section of your thesis or dissertation .

Even if you feel your supervisor did not contribute greatly to the final product, you must acknowledge them, if only for a very brief thank you. If you do not include your supervisor, it may be seen as a snub.

In the acknowledgements of your thesis or dissertation, you should first thank those who helped you academically or professionally, such as your supervisor, funders, and other academics.

Then you can include personal thanks to friends, family members, or anyone else who supported you during the process.
