Science, Technology, Engineering, and Mathematics dissertations have specific conventions that differ from humanities and social science dissertations. Understanding these conventions is key if you're writing in a STEM field. The expectations around measurement, reproducibility, and analytical rigour shape everything from your introduction through your conclusion.
What STEM Dissertations Share
Regardless of whether you're writing a chemistry, engineering, computer science, or mathematics dissertation, certain principles apply across STEM.
Precise measurement matters. Your results aren't opinions or interpretations; they're measurements. A measurement requires precision. You can't write "approximately" when you mean "plus or minus 0.5". You can't round figures without justification.
Reproducibility matters. Another researcher should be able to read your dissertation and replicate your study. This is why your methods section needs to be extraordinarily detailed. You're not just telling the reader what you did; you're telling them how to do it themselves.
Statistical analysis is expected. If your dissertation involves experiments or data collection, you'll be using statistics. You need to understand what statistical test is appropriate for your data, how to run it, and how to interpret and report the results correctly.
Technical report conventions apply. STEM dissertations follow specific structures and styles that differ from humanities essays. Passive voice is often preferred in methods sections. Precision of language is key. Vague language is a weakness.
These principles unite STEM fields despite their differences. Whether you're testing concrete samples, writing algorithms, analysing genomic data, or solving engineering problems, you're operating within a culture of precision and reproducibility.
Sentence variety is an important but often overlooked aspect of academic writing style, since a text that consists entirely of sentences of similar length and structure can feel monotonous and can be harder to read than one with a more varied rhythm. Short sentences can be used to great effect in academic writing when you want to make a point emphatically or to create a moment of clarity after a series of more complex analytical statements. Longer sentences allow you to develop more complex ideas, to express complex relationships between concepts, and to demonstrate the sophistication of your analytical thinking in a way that shorter sentences cannot always achieve. Developing an awareness of sentence rhythm and learning to vary your sentence structure deliberately and purposefully is one of the markers of a skilled academic writer and is something that your tutors and markers will notice and appreciate.
The Labouratory Report Format
Most experimental science dissertations follow the labouratory report format: introduction, methods, results, discussion.
Introduction frames the problem. What's the question you're investigating? What do we already know? What's the gap in knowledge? What are you trying to find out? Your introduction is shorter than in humanities writing, typically 500 to 1,000 words. You're establishing the question and the context. You're not extensive literature review. That comes in a separate literature review chapter if your programme requires one.
Methods is extraordinarily detailed. How did you conduct your experiment or study? What equipment did you use? What are the specifications of that equipment? What procedures did you follow step by step? Another researcher reading your methods should be able to replicate your work. This is the standard. You'll typically spend 1,000 to 2,000 words on methods. It feels excessive until you realise why: reproducibility depends on detail.
Results presents your data neutrally. You're not interpreting yet. You're reporting what you found. If you ran an experiment ten times, report the results from all ten. If some results were unexpected, still report them. Don't cherry-pick results that confirm your hypothesis. Report all results. Present them clearly using tables, graphs, and figures. Explain what each table and figure shows.
Discussion interprets your results against the literature. What do your results mean? Do they support your hypothesis? Do they contradict previous research? Why might that be? What are the limitations? What are the implications? This is where you engage with interpretation and significance.
This structure is standard in STEM. Your dissertation will follow it, and your examiners will expect it.
The quality of your dissertation conclusion will often determine the final impression your work makes on your marker, as it is the last thing they read before forming their overall assessment of your academic achievement. A strong conclusion does more than simply repeat the main points of your dissertation; it synthesises your findings in a way that demonstrates the overall contribution your research has made to knowledge in your field. You should also take the opportunity in your conclusion to reflect on what you would do differently if you were conducting the research again, as this kind of reflexivity demonstrates intellectual maturity and an honest assessment of your work. Ending with a clear statement of the implications of your research and the questions it leaves open for future investigation gives your dissertation a sense of intellectual momentum and leaves your reader with a positive final impression.
Research Integrity in STEM
Data fabrication and falsification are considered serious research misconduct in STEM fields. They're not ethical breaches that might result in a failed module. They're career-ending offences that can result in a degree being revoked years later.
The UK Research Integrity Office provides guidance on research integrity. Their code of conduct, published in 2012, defines good research conduct across UK research. Data integrity, careful attribution, and transparent methodology are central.
This sounds distant from your dissertation. It isn't. If you're inventing data, you're committing research misconduct. If you're cutting outliers from your dataset without reporting that you've cut them, you're committing misconduct. If you're reporting results you didn't actually obtain, you're committing misconduct.
These aren't theoretical concerns. Universities investigate suspected misconduct. If an investigation finds you've falsified data, you'll lose your degree. This has happened to students.
The protection is straightforward: report honestly. If your experiment failed, report that. If you've outlier data points that seem inconsistent, report them and explain how you've handled them. If your hypothesis was wrong, say so. Integrity is stronger than looking right.
Raw Data and Data Management
Your STEM dissertation will involve raw data. Data from experiments, measurements, calculations, or observations. What happens to this data?
Some dissertations include raw data in an appendix. Some include sample data and archive the full dataset separately. Some require you to upload data to a data repository.
Data management plans are increasingly required. A data management plan describes what data you'll collect, how you'll store it, how you'll ensure it's secure, how you'll preserve it, and whether you'll make it openly available.
The FAIR data principles are increasingly standard in STEM research. FAIR is an acronym: Findable, Accessible, Interoperable, Reusable. Data should be easy to find, available to others, able to be integrated with other data, and usable by others.
Your university will have data management policy. Check it. Some data needs to be archived for at least ten years. Some data is sensitive and needs secure storage. Some data should be made publicly available. Your dissertation might be required to include or reference your data management plan.
This seems bureaucratic. It serves a purpose: it ensures that if your work is important, other researchers can access your data and verify your findings or extend your work.
Technical Writing in STEM
STEM writing has distinctive conventions around voice, precision, and presentation.
Passive voice is often preferred in methods sections. "Data were collected using..." rather than "I collected data using...". This isn't because the active voice is wrong; it's convention. Some STEM programmes now accept active voice more readily, particularly in results and discussion sections. Check your programme's guidance.
Precision is most important. Not "the temperature was hot". Was it 45 degrees Celsius? 120 degrees Celsius? The precision matters. Not "results indicated a relationship". What was the correlation coefficient? What was the p-value?
Considerable figures matter. If you measured something to the nearest 0.1 milligram, don't report your results to the nearest microgram. Don't report a measurement as "3.500000 grams" when your equipment measures to the nearest 0.01 gram. Considerable figures indicate the precision of your measurement.
Units matter. Always include units. Not "the sample was 50". Fifty what? Grams? Millilitres? The units are part of the measurement.
Presenting Equations and Statistical Results
Equations in STEM dissertations should be formatted consistently. Number them so you can refer to them later. Use consistent notation. If X represents concentration in your first equation, don't use X to represent time in your second equation. This creates confusion.
Statistical results need to be reported with specific information. Not "the result was considerable". Report the test statistic, the degrees of freedom, the p-value, and the effect size. "A t-test revealed a considerable difference between groups (t(48) equals 2.45, p equals 0.018, d equals 0.71)." This tells the reader exactly what you did and what you found.
Confidence intervals are increasingly preferred over p-values because they give more information about uncertainty. You can report both.
Your STEM style guide will specify how to present equations and statistics. Consult it and be consistent.
The Difference Between a STEM Dissertation and a Lab Report
A lab report is a brief document describing a single experiment. A STEM dissertation is a more thorough research project, usually involving multiple experiments or studies, extensive literature review, and original contribution to knowledge.
A lab report might be 5,000 words. A dissertation is 10,000 to 20,000 words or longer depending on your level.
A lab report follows the experiment in the same week or the same month. A dissertation is conducted over a semester or a year.
A lab report is assessed primarily on technical competence and accuracy. A dissertation is assessed on technical competence, literature knowledge, original research contribution, and critical reflection.
But they share the basic structure: introduction, methods, results, discussion.
Frequently Asked Questions
Q: Should I use passive or active voice in my STEM dissertation? A: Check your programme's guidance. Passive voice in methods sections is traditional ("Samples were prepared by..." rather than "I prepared samples by..."). However, active voice is increasingly accepted. Many supervisors prefer active voice because it's clearer and more engaging. In results and discussion sections, active voice is often standard. The key is consistency within your dissertation. If you use passive in methods, consider whether to stay passive or switch to active in results. Ask your supervisor.
Q: How should I present error bars and uncertainty in graphs? A: Error bars should clearly indicate what they represent. Are they standard deviation? Standard error? Confidence intervals? This should be stated in the figure caption. If different graphs show different types of error, you should be consistent or clearly note the difference. Include in your methods what type of uncertainty you calculated and why.
Q: What if my results contradict my hypothesis? A: Report them honestly and discuss what they mean. Science often moves forwards by finding that hypotheses were wrong. Disproving a hypothesis isn't a failure. Failing to report results that contradict your hypothesis is misconduct. Science progresses by finding out what's actually true, not what we expected to be true.
