Using the Feynman Technique to Prepare an Oral Presentation

You know the topic. You could pass a test on it without any trouble. But the moment you stand up in front of the class with your presentation open, the words get tangled, you jump from one idea to another with no connection, and you end up reading the slides like a life raft. The problem isn’t your knowledge: it’s that you never translated it into a speech someone else can follow. That’s exactly where the Feynman method for presentations makes the difference.

Richard Feynman didn’t design his technique with oral presentations in mind, but its logic fits like a glove: if you can’t explain something in simple words, you don’t understand it well enough yet to present it. Applying the Feynman technique for oral presentations forces you to move from “I know the content” to “I can communicate it clearly,” which is exactly what gets evaluated in any presentation.

Why knowing the topic isn’t enough to present it well

There’s a very common mental trap: confusing recognizing information with being able to explain it. When you read your notes or review slides, your brain recognizes the content and gives you a false sense of mastery. But speaking in public demands something different: rebuilding that information from scratch, in real time, with a structure someone else can follow without having studied the topic.

That’s why so many students freeze up during the presentation even after getting a good grade on the written assignment. Writing lets you correct, delete, rephrase. Speaking doesn’t. That’s why it’s worth training oral explanation as a separate skill, not just as a summary of the text.

The four steps applied to a presentation

The original method has a simple logic you can directly adapt to prepare a presentation with the Feynman method:

• Choose the central concept of your presentation, not every subtopic at once.
• Explain it out loud as if you had someone in front of you who knows nothing about the topic.
• Spot where you stumble, hesitate, or use vague phrases like “and that makes this happen.”
• Go back to the source, clarify that point, and repeat the explanation until it flows without filler words.

If you want to dive deeper into the full logic behind each phase, you’ll find the complete breakdown in the 4 steps of the Feynman method explained.

Turn your notes into a spoken script, not a read one

The most common mistake when preparing a presentation is writing a formal text and then trying to memorize it. It sounds artificial, and as soon as you forget a word, your mind goes blank. The alternative: explain the topic out loud in your own words, record yourself or simply listen to yourself, and build the script from that oral explanation. That way the speech is born spoken, not written, and sounds natural because it is.

This idea of learning by explaining in your own words is the foundation of the whole method; you can explore it in depth in the Feynman method: learn by explaining in your own words.

Spot your gaps before the audience does

When you practice your presentation out loud and find yourself repeating generic phrases or going in circles, that’s exactly the weak spot a teacher or classmate could catch with an uncomfortable question. Better to find it yourself, in your room, than live in front of the class.

Watch for three warning signs while you rehearse:

• You use the word “thing” or “that” instead of a precise term.
• You skip a transition by saying “and then” without explaining the causal link.
• You repeat the same sentence in different words without adding new information.

Simplify the language without losing rigor in the content

Speaking in public with the Feynman technique doesn’t mean dumbing down the content. It means removing unnecessary jargon and replacing it with analogies, concrete examples, and short sentences your audience can follow without extra mental effort. Technical accuracy stays in the data and concepts; what changes is the verbal wrapping.

A good exercise: imagine you have to explain your topic to a classmate in a lower grade. If your explanation would still be correct and understandable for that person, it will probably work for your current class too.

Structure your speech like a story with internal logic

A clear explanation isn’t just simple language, it’s also order. Before rehearsing out loud, mentally sketch the thread: what problem or question opens the topic, what idea solves it, what evidence supports it, and what practical conclusion follows. That narrative skeleton keeps the presentation from turning into a list of loose facts.

If you struggle to visualize that structure with words alone, combining oral rehearsal with a visual outline of the topic can help you lock in the order before speaking.

Rehearse with real, timed blocks

One of the most common mistakes when preparing an oral presentation is not measuring how much time each part of the speech actually takes. You rehearse it mentally and it seems to fit in five minutes, but once you say it out loud it takes ten. The solution is simple: split your preparation into defined time blocks, rehearse each section separately, and actually time it.

For this it helps to rely on timed study and rest cycles, with an alarm: you dedicate one block to rehearsing a section of the presentation out loud, take a break, and then review which parts tripped you up before moving on to the next block. This rhythm keeps preparation from turning into an exhausting marathon the night before.

Practice in front of a real person (or simulate it)

The method works best when there’s an audience who can ask you questions, even if it’s just one classmate or a family member. Their doubts show you in real time which parts of your explanation weren’t clear. If you don’t have anyone available, recording yourself on video and watching it back serves a similar purpose: you distance yourself from your own speech and notice the same things an outside listener would.

Afterward, write down every stumble and go back to the source to reinforce that specific point, exactly as you would when studying a topic with the classic method.

Control body language without neglecting the content

Presentation clarity doesn’t depend only on words. Voice pacing, pauses, and eye contact strengthen or weaken a well-built speech. However, that comes later: if you first master the content with clear explanations and no read-along support, body language improves almost on its own, because you’re no longer spending mental energy trying to remember what to say.

That’s why it’s worth reversing the usual order: first master the oral explanation of the content, then work on the staging. Trying it the other way around usually produces a presentation that looks confident but sounds empty as soon as questions come up.

Frequently Asked Questions

Does the Feynman method work for any type of oral presentation?

Yes, it works equally well for a literature presentation, a lab report, or a history assignment, because its foundation doesn’t depend on the content but on the skill of translating complex ideas into simple, ordered language. The topic changes, but the process of explaining, spotting gaps, and simplifying is the same.

How long before the presentation should I start practicing this way?

Ideally several days ahead, because you need room to spot your weak points, go back to the source material, and rehearse again. Doing it the night before only lets you memorize superficially, not build a fluid, natural explanation.

Is it a problem to rely on slides if I use this method?

Using slides isn’t a problem, but they should be visual support, not a script to read. If your oral explanation is solid thanks to practice, the slides become a reminder of the structure, not the text you recite word for word.

What should I do if I get nervous even though I know the content well?

Nerves tend to drop when the explanation is so well practiced that you don’t need to think about what word comes next. Practicing out loud several times, with timed sessions and in front of a real person whenever possible, reduces much of that anxiety because your brain recognizes the speech as something already traveled.

Should I write the full speech before rehearsing it out loud?

It’s better the other way around: explain it out loud first in your own words, and from those already fluid explanations, write the script or supporting notes. Writing a formal text first and memorizing it afterward tends to sound artificial and makes it easier to freeze if you forget an exact phrase.
