Writing Your Thesis

The terms "thesis" and "dissertation" are used interchangeably in some countries and differently in others. In the UK and Australia, a "thesis" typically refers to a PhD document; a "dissertation" is the master's equivalent. In the US, it's often reversed. This guide uses "thesis" to cover both — the principles apply regardless of what your institution calls it.

Thesis vs. Dissertation vs. Essay

Understanding what makes a thesis different from other academic writing is the starting point for writing one successfully.

What "Original Contribution" Actually Means

This is the phrase that terrifies most thesis students. You don't need to discover a new law of physics. Originality in a thesis can mean:

• New data — conducting research that hasn't been done before (new population, time period, context)
• New application — applying an existing framework to a new domain or context
• New synthesis — bringing together ideas from two separate fields in a novel way
• New critique — challenging or refining existing theory with empirical evidence
• New method — developing or adapting a methodological approach

Thesis Structure

Most theses follow a six-chapter structure, though this varies by discipline. Sciences often use IMRaD (Introduction, Methods, Results, Discussion) within a broader framework; humanities often use thematic or argument-based chapters.

• Abstract — 300–500 words summarising the research question, method, findings, and contribution
• Introduction — the research problem, your research question, the gap you're addressing, and the structure of the thesis
• Literature Review — critical synthesis of existing scholarship; ends with your research rationale
• Methodology — your research design, justified with reference to your epistemological position
• Findings/Results — what your data shows, presented without interpretation
• Discussion — your interpretation of findings in relation to the literature and your research question
• Conclusion — direct answer to your research question, limitations, and future research directions

Writing Each Chapter Without Getting Stuck

Introduction: don't write it first

Many students agonise over the introduction before they know what they're introducing. Draft it early as a roadmap, but revise it last — after you know exactly what your thesis has proven.

Literature review: theme first, source second

Don't organise by "what each paper says." Identify the themes in the existing research first, then pull sources into each theme. This produces analysis, not annotation.

Methodology: justify, don't just describe

Every methodological choice — why interviews rather than surveys, why 20 participants, why thematic analysis rather than discourse analysis — needs justification. Ground your choices in methodological literature.

Findings: separate from interpretation

In empirical theses, findings and discussion are separate chapters. Resist the temptation to interpret in the findings chapter. Present what you observed; save "what it means" for the discussion.

Discussion: connect the dots

Structure your discussion around your research questions or objectives. For each: what did you find, what does it mean, how does it connect to the literature, and what does it contribute?

Working with Your Supervisor

• Meet regularly — supervisors are not mind-readers. Regular meetings keep you on track and surface problems before they become crises.
• Always bring written work — even rough notes or bullet points. Supervisors can respond to text far more usefully than to verbal updates.
• Ask specific questions — not "Is this okay?" but "Is my research question specific enough to answer in 80,000 words?" or "Does my methodology justify my sampling strategy adequately?"
• Keep a supervision log — record what was discussed and agreed. This protects you if there's later disagreement about what feedback was given.

Preparing for the Viva

A viva (oral examination or thesis defence) is a conversation about your research — its strengths, limitations, and contribution. Examiners want to know that you understand your research deeply, not just that you wrote it.

• Reread your thesis thoroughly before the viva — know exactly what you argued in every chapter
• Know the literature well — examiners often ask about papers you cited
• Prepare to articulate your contribution in one or two sentences
• Acknowledge limitations honestly — examiners respect self-awareness
• It's acceptable to say "That's an interesting question — let me think for a moment" before answering
