A dissertation conclusion is the final chapter that answers your research questions, states your contribution, and shows what your study changed.
A dissertation conclusion is the final chapter that answers your research questions, states your contribution, and shows what your study changed.
For Vietnamese postgraduate researchers writing in English, the conclusion is the chapter an examiner reads most closely against the introduction — where a thesis either lands its argument or quietly under-sells it. This guide answers the seven questions Vietnamese master's and doctoral students ask MAAS mentors most when they reach chapter six.

What is a dissertation conclusion actually for?
Direct answer: The conclusion has one job: to tell the reader what your study now allows the field to know that it did not know before. It answers the research questions you set, names your contribution, acknowledges limits, and points forward. It is an argument about significance, not a recap of every chapter.
Evidence: Bunton (2005), analysing 45 PhD conclusion chapters across disciplines, found that a strong conclusion does far more than summarise — it revisits the study's purpose, consolidates the research space the thesis has built, and projects outward into applications and future work. The summary is a small part of a chapter whose real function is to claim the value of what was done.
Example: A MAAS-coached master's student in education wrote a conclusion that re-narrated her three findings and stopped. Her mentor asked one question — "so what is now true that wasn't before?" — and the chapter was rebuilt around the answer, reading as a contribution rather than a recap.
How is the conclusion different from the discussion chapter?
Direct answer: The discussion interprets your results in detail and argues what they mean; the conclusion stands above the whole thesis and states what it all adds up to. The discussion works close to the data; the conclusion works at the level of the field. Repeating the discussion in your conclusion is the single most common structural error.
Evidence: Swales and Feak (2012) describe the conclusion as the chapter that "zooms out" — moving from specific results back to broad significance, the mirror image of the introduction's funnel. Where the discussion answers "what do these results mean?", the conclusion answers "why does this thesis matter, and what should happen next?"
Example: A Vietnamese doctoral candidate in management submitted a conclusion that was, in effect, a second discussion. Her MAAS mentor used the table below to separate the two chapters: the discussion kept the interpretation, the conclusion was cut to contribution, limits, and recommendations, and the redundancy an examiner would have flagged disappeared.
| Feature | Discussion chapter | Conclusion chapter |
|---|---|---|
| Altitude | Close to the data | Above the whole thesis |
| Core question | What do the results mean? | What does the thesis contribute? |
| New interpretation | Yes — this is where it belongs | No — synthesise only |
| Literature | Compares findings to prior studies | Restates the gap now filled |
| Forward look | Brief | Central (future research, practice) |
What moves should a dissertation conclusion contain?
Direct answer: A complete conclusion moves through a recognisable sequence: restate the purpose and questions, consolidate what the study found and contributes, state limitations, give practical implications or recommendations, and propose future research. Naming each move as you draft stops you from ending the thesis on a summary and forgetting the contribution.
Evidence: Bunton (2005) identified the moves below as the recurring structure of PhD conclusions, with the consolidation of the research space — restating findings, claiming contribution, comparing to the literature — as the chapter's centre of gravity. Chen and Kuo (2012), studying master's theses in applied linguistics, confirmed a similar pattern at master's level, showing the structure scales down from doctoral work.
Example: A MAAS client in finance had a conclusion with strong findings but no explicit contribution or future-research move. Walking through the moves below, he added two short sections — one naming his theoretical contribution, one proposing follow-up studies — and the examiner's "what next?" question was answered before it was asked.
| Move (Bunton, 2005) | What you do | Signal phrases |
|---|---|---|
| 1 — Restate purpose and questions | Remind the reader what the thesis set out to do | "This study set out to…" |
| 2 — Consolidate the research space | Synthesise key findings and name the contribution | "Taken together, these findings show…" |
| 3 — State limitations | Define what the study could and could not establish | "These results should be read in light of…" |
| 4 — Practical implications | Show what the findings mean for practice or policy | "For practitioners, this suggests…" |
| 5 — Recommend future research | Point to the next questions your work opens | "Future studies could examine…" |
How do you state your contribution to knowledge without over-claiming?
Direct answer: State your contribution in proportion to your evidence. Name what is genuinely new — empirical, theoretical, or practical — in one or two clear sentences, then bound it: this population, this context, this design. Examiners reward a precise, defensible claim far more than a sweeping one your data cannot support.
Evidence: Bunton (2005) found that successful conclusions consolidate the research space by explicitly linking findings back to the gap named in the introduction, rather than asserting broad importance. Murray (2017) frames the contribution as a claim you must be able to defend at the viva — every word should survive the question "how do you know?"
Example: A Vietnamese PhD candidate in public health wrote that her study "transforms understanding" of a behaviour. Her MAAS mentor reframed it as a specific, bounded empirical contribution — new evidence from an under-studied population, with the limits stated in the same breath. The smaller claim was stronger, and held up cleanly at the viva.
How do you write limitations and recommendations that strengthen the thesis?
Direct answer: Treat limitations as the honest foundation for your recommendations, not as an apology. State each real limit plainly, explain what it does and does not affect, and let it open directly into a targeted recommendation or future-research direction. A well-framed limitation makes a thesis look more credible, not less.
Evidence: Murray (2017) argues that examiners read limitations as a test of judgement: candidates who name their boundaries clearly show the critical self-awareness a doctorate certifies. Bunton (2005) shows recommendations and future-research moves are standard, expected components — their absence reads as an unfinished argument rather than a modest one.
Example: A MAAS doctoral client buried her sampling limitation in a defensive sentence. Her mentor turned it into a paired structure — the limit, then the future study it justifies. What had looked like a weakness became the springboard for her recommendations.
How long should the conclusion be, and what should it never do?
Direct answer: As a rough guide, the conclusion runs roughly 5–8% of the thesis — often a few pages at master's level and longer for a PhD — but completeness of the moves matters more than length. The one firm rule: a conclusion must never introduce new data, new results, or a new argument the body did not establish.
Evidence: Swales and Feak (2012) and Murray (2017) both warn that new material in a conclusion signals an analysis that was not finished in the right place; everything here should already be earned in the body. Bunton (2005) found that even short conclusions work when they complete the core moves, while long ones fail when they merely re-run the discussion.
Example: A MAAS client in education slipped a fresh sub-finding into her conclusion because "it didn't fit anywhere else." Her mentor moved it back into the results, where it could be properly evidenced, and the conclusion returned to its job — synthesis, not new analysis.
What conclusion mistakes do Vietnamese and other ESL researchers make most?
Direct answer: The most common pattern in second-language theses is a conclusion that summarises thoroughly but states the contribution weakly — the writer recaps each chapter yet never sharpens the single claim the examiner is waiting for. Other frequent issues are a missing future-research move and a conclusion that drifts back into discussion.
Evidence: Nguyen and Pramoolsook (2016), analysing TESOL master's thesis conclusions written by Vietnamese postgraduates, found the deduction-and-contribution move present in every chapter but other moves only conventionally realised, with traces of Vietnamese rhetorical habits shaping the English structure. Paltridge and Starfield (2019) note more broadly that second-language thesis writers often master the descriptive, summarising moves while underplaying the evaluative move that claims significance.
Example: A Vietnamese master's candidate's conclusion summarised all five chapters but never said what the field should take from her work. Her MAAS mentor used the contribution move as a one-sentence checklist — "this thesis shows that…" — and the claim implicit across forty pages finally appeared where an examiner looks for it.
Frequently asked questions
How long should a dissertation conclusion be?
A common guide is 5–8% of the total word count — often a few pages for a master's dissertation and longer for a PhD. Treat this as a rough range, and always follow your department's and supervisor's specific guidance over any general figure.
What is the difference between the discussion and the conclusion?
The discussion interprets your results in detail and argues what they mean; the conclusion stands above the whole thesis and states what it all contributes, what its limits are, and what should happen next. Avoid re-running the discussion in your conclusion.
Can I introduce new findings in the conclusion?
No. The conclusion synthesises material the body already established. New data, results, or arguments belong in the relevant earlier chapter, where they can be properly evidenced before you draw on them.
How do I state my contribution without over-claiming?
Name what is genuinely new in one or two sentences and bound it to your population, context, and design. A precise, defensible contribution that survives the question "how do you know?" is stronger than a sweeping claim your data cannot support.
Should limitations go in the discussion or the conclusion?
Either can be conventional depending on your discipline and department, but the conclusion is a natural home when you pair each limitation with the recommendation or future-research direction it justifies. Follow your supervisor's preferred structure.
