Key information
- ✓First, determine the time of your speech, then the number of slides.
- ✓One slide should convey one main idea.
- ✓Pay most attention to the goal, method, results and conclusions.
- ✓Practice your statement with the watch and prepare a shorter version of your presentation.
How many slides should a presentation have?
Most often, 8 to 12 slides are enough. The presentation should not be overloaded with text, because the committee knows the topic of the work and expects, above all, a clear discussion of the most important elements.
It is better to prepare fewer slides but discuss them well than to create a long presentation that cannot be presented in the allotted time.
What should be included in the presentation?
The presentation should include the topic of the work, purpose, research problem, methods, most important results, conclusions and a short summary.
If the work had a research part, it is worth showing 1-3 most important charts or tables. It is not necessary to show all results.
How to design slides?
Slides should be simple and legible. Too much text makes it difficult to read and makes the presentation look less professional.
It's best to use short points, large headings, charts and simple graphics. Each slide should have one main message.
How to prepare for a speech?
It's a good idea to practice your presentation aloud a few times. This makes it easier to control the time and fluency of speech.
It is also a good idea to prepare answers to questions about the topic, methodology, results and conclusions of the work.
Proposed layout of slides for defense
The safe layout includes a title slide, justification for choosing the topic, research goal and problem, brief information about the method, two or three slides with the most important results, conclusions and conclusion. If the university has provided its own scheme, it takes precedence over any online guide.
Not every piece of work deserves a separate slide. An extensive description of literature can be reduced to one board with a model or the most important concepts. The committee is usually more interested in what has been examined and what the results show.
Charts, tables and data - what do you really show?
Select results that answer your main research questions. The chart should have a clear title, description of the axis and units. If the recipient needs several dozen seconds to understand the legend, the graphics are too complex for a short presentation.
A table is useful when accurate values are important. A simple graph may be better to show the direction of differences. Do not copy wide tables from your work without changes - their text will become unreadable on the projector screen.
Committee questions and contingency plan
Prepare short answers to questions about topic selection, study limitations, sample selection, and the most important conclusion. It's not about learning formulas, but about organizing arguments that you can return to under stress.
Save your presentation in source and PDF formats, use standard fonts and have a copy in two places. If an animation or video doesn't work, the slide should still convey the meaning without additional effects.
First decide what central story the examination committee should remember
A thesis defence presentation should lead from the problem through the approach to the main result. Before opening presentation software, write these three elements in a few sentences. If you cannot briefly explain your thesis objective, elaborate graphics will not solve the problem. Choose one main message and two or three supporting arguments. Other details can remain in your spoken explanation or backup slides.
Check the degree examination rules for your programme: whether a presentation is required, how much speaking time is available and whether a particular template applies. Do not assume that the slide count suggested in a guide applies to every university in Poland. Establish how to submit the file and which equipment is available. These details affect the presentation structure more than an attractive theme. You should be able to present the material calmly within the time actually allocated.
An example slide structure for an empirical thesis
Educational example: after the title slide, present the problem and objective, then the research questions, method and sample, key findings, limitations and conclusions. This is an argumentative sequence, not a compulsory number of slides. A result requiring a chart explanation may need its own slide. A brief sample description can be combined with the method. Avoid copying the entire thesis contents page, as it does not explain what the work achieved.
In an engineering thesis, the design problem, requirements, solution selection, implementation and testing may deserve greater emphasis. Do not add a survey merely to fit a social-science presentation template. The structure should match the actual nature of your work. Write one sentence you intend to say for each slide. If two slides serve the same sentence and add no new information, consider combining them.
How to present a result without a wall of text or an unreadable table
Choose a chart or table that answers a specific question. Provide a clear title, units and necessary labels, then state the main conclusion in a separate sentence. Do not paste a screenshot of an entire calculation sheet. The committee should quickly recognise what you are comparing and why it matters to the thesis objective. If you show percentages, give their calculation base. For qualitative findings, use a short participant quotation to illustrate an identified pattern.
Do not conceal limitations by truncating axes, omitting categories or selecting only favourable findings. A presentation summarises a thesis, but that summary must preserve the analysis's meaning. When a table contains many values, highlight the item currently being discussed and move the complete version to backup material. All figures should match the final document. A discrepancy between a slide and the thesis can easily prompt unnecessary questions during the defence.
Timed rehearsal and shortening your speech
Rehearse aloud using the slides you actually intend to present. Reading notes silently usually gives a misleading impression of the time required. Mark the passages where you spend too long or start explaining peripheral issues. Remove digressions and repetition first. Do not accelerate the whole presentation until the methodology and findings become difficult to understand. Leave room for calm transitions between sections.
After rehearsing, ask a listener to restate the objective, method and main finding. If they mainly remember an interesting detail from the introduction, adjust the balance. Prepare a shorter version in case the committee asks for a concise account of the work. It should retain the problem, result and significance. It need not include every definition or the detailed history of the project. Deliberately selecting content provides more control than memorising the entire presentation word for word.
A contingency plan and backup slides
Save the presentation in an editable format and as a PDF if university rules allow it. Check both files on another device, particularly fonts, charts and symbols. If you demonstrate software, also prepare static screenshots of the essential stages. Do not make the entire presentation depend on an internet connection or a single video. Give the file a clear name and remove outdated versions from the storage device used for the examination.
Backup slides may contain instrument details, additional results, a solution diagram and the rationale for an important choice. Open them only when they help answer a question. They should not conceal key limitations or extend the presentation beyond the agreed time. The final check should cover consistency with the thesis, readability from a distance and your ability to explain the essential elements even without displaying the slides.
Summary
A defense presentation is primarily intended to help you talk calmly and logically about the work you have done. The Commission does not expect a summary of each chapter, but a clear presentation of the purpose, research method, key results and conclusions. Simple slides, practiced pacing, and knowing your own research decisions provide much more confidence than extensive animations or large amounts of text.
Frequently asked questions
How many slides should you prepare for 10 minutes?
Most often, 8-10 substantive slides work best. The pace depends on the amount of data and the way you speak, so a practice speech is more important than a hard number.
Can you read text from slides?
It's better to treat the slide as a landmark. Short slogans help maintain the flow of speech, while reading entire paragraphs weakens contact with the committee.
Do I have to show the entire bibliography during the presentation?
Usually not. You can indicate the most important sources or add a final slide with selected literature if university policy requires it.
Should I read out the text on each slide?
No. Slides should orient the audience, while your speech explains relationships, choices and the result's significance. A slide containing the entire spoken script usually needs simplifying. Brief presenter notes can help, but practise explaining your own work independently.
Need support with your work?
Describe the topic, scope and deadline. We will review the materials, recommend the right support and prepare a clear quote.
