Verb tenses in academic writing – by section

9th June 2020 blog

Academic papers are written mostly in the present simple, past simple, and present perfect tenses, which are covered in our overview of verb tenses. This article offers general guidelines on which verb tenses to use in each section of a thesis, dissertation, or research paper. Note that there may be exceptions; always consult the style guide used in your academic field for confirmation.

In addition to consulting these guidelines, we recommend that you work closely with your academic supervisor as you write and format your paper. Some academic disciplines have very specific requirements regarding the use of tenses, so it’s important to consult academics who are used to writing in your subject area, as well as the relevant style guidelines issued by your university or the journal you hope to be published by.

Abstract or summary

Use the present simple tense to state what the paper investigates and what its goals are, and to report general facts that continue to be true.

This study explores the potential clinical uses of topical compounds.

Use the present perfect tense to discuss past research that is relevant to the current study.

Use the present simple tense to explain what the paper is about, how it is structured, and why it’s important, and to define terms and share facts that are widely known and won’t change over time.

Chapter 4 describes the research methodology.

The theory that all actions are intrinsically right or wrong is known as moral absolutism.

Use the past simple tense to provide historical background and context.

Use the present perfect tense to present past research that is relevant to your study.

Theoretical framework

Use the present simple tense to describe theories and define terms.

Literature review

Use the past simple tense to discuss the findings of earlier studies.

Use the present simple tense to state facts that do not change over time, to express opinions or propose a thesis statement, and to narrate the plot of a literary work.

Use the present perfect tense to introduce past research that is relevant to the current study, to address a gap in the current knowledge base, and to correct a dated theory that is no longer accurate.

Previous studies have found that almost one quarter of teenagers experience cyberbullying.

Methods and results

Use the past simple tense to detail your experiments and to discuss events that began and ended in the past. If your paper must avoid using the first person, you will likely use the passive voice in this section, foregrounding the actions taken rather than the researcher(s) who took them.

Discussion and conclusions

Use the present simple tense to interpret data or express an opinion, and to report facts that are unlikely to change in the future.

Recommendations and implications

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, use modal verbs, such as can, should, and may; verbs that suggest uncertainty, such as believe, assume, suggest, imply, and expect; and hedging words, such as likely and possibly.

Teacher burnout will likely continue at a high rate.

Early intervention could mitigate these effects.

Use the present simple tense to make recommendations or express opinions. If you are required to avoid using the first person, you may need the passive voice in this section.
