How to Write a Dissertation Introduction That Gets Top Marks

The dissertation introduction is the section most students get wrong — not because it's the hardest part to write, but because they write it first. Professional academic writers almost always write the introduction last, once they know exactly what their dissertation has argued and proven. This guide shows you what to include, in what order, and why each element matters to markers.

What Your Introduction Must Achieve

Your introduction has three core jobs: orient the reader to your topic, establish why the topic matters, and tell the reader exactly what your dissertation will do. It is not a place to write general background or summarise the literature — that's what your literature review is for. Markers at every level are looking for a clear, purposeful opening that demonstrates you understand the academic problem you are addressing.

Step 1: Open With Context

Your first paragraph should move from a broad, established context down to your specific focus — the academic equivalent of a camera zooming in. State the field, acknowledge its significance, then narrow to the problem your dissertation addresses. Avoid grand, vague openers like 'Since the dawn of time...' — they signal to markers that you don't know how to enter an academic argument.

Step 2: Identify the Research Gap

This is the most intellectually important element of your introduction. You need to show that existing literature, while valuable, has left something unanswered, understudied, or contested. This gap is the reason your dissertation exists. Phrases like 'however, little attention has been paid to...' or 'existing studies have not explored...' signal to markers that you understand how to position yourself within an academic field.

Step 3: State Your Research Questions

After establishing the gap, state your research questions or aims clearly and directly. Most undergraduate and Masters dissertations have 1–3 research questions. They should be specific, answerable within your scope, and directly linked to the gap you have identified.

• Be specific: 'What factors influence X in the context of Y?' outperforms 'What are the main issues with X?'
• Make them answerable: your methodology must be capable of addressing each question
• Avoid questions with yes/no answers — these rarely produce strong dissertations
• Link each question back to the gap you identified

Step 4: Outline Your Methodology

A brief methodological overview belongs in the introduction — not a full chapter, but a sentence or two explaining your overall approach. Are you using qualitative or quantitative methods? Primary or secondary data? This signals to markers that you have a clear, deliberate research design rather than an ad hoc approach.

Common Mistakes to Avoid

• Starting with dictionary definitions — this is a signal of underprepared writing
• Writing too broadly for too long before narrowing to your topic
• Burying your research questions at the end of a long paragraph
• Including literature review content in the introduction
• Stating aims that don't match what your dissertation actually does
