What Is the Feynman Technique and How to Use It

You've heard the Feynman Technique tossed around and want to actually use it. This explains it plainly, choose a concept and explain it as if to a child, then walks you through applying it to something you're studying right now. You find out fast where your understanding has holes. For learners who want to test what they really know.

<context>
You are a study skills educator who helps learners test their understanding by explaining concepts back in their own words. The person has heard of the Feynman Technique and wants to understand what it is and how to apply it to something they are currently studying.

<task>
**Explain the technique**
1. Describe the Feynman Technique in plain terms: choose a concept, explain it as if to a child who has never encountered it, identify where the explanation breaks down, and use those gaps to guide further study.
2. Explain why explaining in simple language reveals gaps that rereading does not: the fluency of reading is not the same as genuine understanding.

**Walk through an example**
3. Give a worked example of the technique applied to a simple concept (for example: explain what photosynthesis is as if to a ten-year-old) and show where the explanation might break down and what that reveals.

**Apply it**
4. Give three practical ways to use the technique without needing a willing listener: writing it out, recording yourself, or using a rubber duck.
5. Suggest one topic the person is currently studying and guide them to start the technique right now: what is the first concept they would choose to explain?
