How to Write a Dissertation Introduction
The introduction is the first chapter a reader sees and usually the last one you should finish. Its job is to make the case that your research question is worth answering.
A strong introduction does not try to cover everything. It moves the reader in a controlled sequence from a broad area of interest to the specific question your dissertation answers, and then tells them how the rest of the document will answer it. Markers often form their view of a dissertation within the first few pages, so it repays careful drafting and redrafting.
Draft early, finalise last
Writing a rough introduction early helps clarify your thinking and gives you something to show your supervisor. But your project will change as you research, analyse and write, so the final version should be written once everything else is complete. Only then do you know exactly what the dissertation argues and how the chapters fit together.

Establish the context
Begin by situating your topic in its wider field: why the area matters, what is happening in it and who is affected. Keep this brief and relevant — a paragraph or two in most dissertations. Avoid sweeping openings such as “since the dawn of time” or dictionary definitions. A specific, evidenced statement about the importance of the issue is a stronger start.
Weak: “Technology has changed the world in many ways.”
Stronger: “Remote working among knowledge workers has grown sharply since 2020, yet evidence on its effects on early-career staff remains limited.”
Define the problem
Move from context to a specific problem: something unresolved, contested or poorly understood that your research addresses. The problem might be practical (an issue in a particular setting) or theoretical (a gap or inconsistency in existing explanations). State it clearly in one or two sentences so the reader cannot miss it.
Identify the gap in existing research
Briefly show what is already known and where knowledge stops. This is not the full literature review — that comes in its own chapter — but a concise summary that establishes the gap your study fills. The gap might be a population, setting, method or question that previous research has not addressed. Make sure the gap is real; markers will check it against your literature review.
State your aims, objectives and research questions
This is the centre of the introduction. The aim is a broad statement of what the study sets out to achieve. Objectives are the specific steps you will take to achieve it. Research questions state precisely what the study will answer. Hypotheses, if appropriate to your design, state testable predictions.
Keep them aligned
Every objective should serve the aim, and every research question should be answered somewhere in your results and discussion. Check this alignment before submitting.
Explain the significance
Tell the reader why your study matters: what it contributes to knowledge, practice or policy, and who might benefit from the findings. Be confident but realistic — a master’s dissertation contributes in a focused way, and overclaiming invites scepticism. A paragraph is usually enough.
Clarify scope and key terms
Explain what the study covers and what it deliberately excludes, and why. Defining the boundaries early prevents examiners from criticising you for not addressing things you never set out to address. If key terms are contested or used in specific ways in your study, define them here or point to where they are defined.
Write with the reader in mind
Your introduction should be understandable to an intelligent reader outside your immediate specialism, such as a second marker from a related area. Define technical terms, avoid assuming knowledge of niche debates and keep sentences direct. Every paragraph should move the reader closer to your research question. If a paragraph provides interesting background but does not contribute to that movement, it probably belongs in the literature review or nowhere.
Briefly indicate your approach
Some disciplines expect a short note on methodology in the introduction — for example, that the study uses semi-structured interviews or a quantitative survey. One or two sentences is enough; full justification belongs in the methodology chapter.
Provide a chapter outline
End the introduction with a brief map of the dissertation: one or two sentences per chapter explaining what it contains and how it contributes to answering the research question. This helps the reader navigate and demonstrates that the document has a deliberate structure.
| Element | Typical length (10,000–15,000 word dissertation) |
|---|---|
| Context and problem | 300–500 words |
| Gap and rationale | 200–400 words |
| Aims, objectives, questions | 150–300 words |
| Significance and scope | 200–300 words |
| Chapter outline | 150–250 words |
Common mistakes to avoid
- Opening too broadly and taking several pages to reach the topic.
- Turning the introduction into a full literature review.
- Leaving the research question implicit or buried in the middle.
- Listing aims and objectives that the dissertation never addresses.
- Describing chapter contents without showing how they connect.
- Writing it first and never revising it to reflect what the dissertation became.
Most of these are fixed in a single focused redraft once the rest of the dissertation is complete.
Check it against your conclusion
Once both chapters are written, read your introduction and conclusion side by side. The questions posed at the start should be the ones answered at the end, in the same terms. If the project’s focus shifted during the research, revise the introduction to match the dissertation you actually wrote. This final consistency check is one of the simplest ways to make the whole document feel coherent.
