The Feynman Technique is a study method named after the physicist Richard Feynman, who was known for explaining complex ideas in simple language. The core idea is simple: if you cannot explain something simply, you do not fully understand it yet.
The good news is that you do not need a study partner. This guide shows you how to use the Feynman Technique completely on your own, step by step, with an example.
The 4 Steps
Step 1: Choose a Concept
Write the topic at the top of a blank page, for example “photosynthesis” or “supply and demand”.
Step 2: Explain It as if to a 12-Year-Old
Without looking at your notes, write or say an explanation in plain words. Avoid jargon; if you must use a technical term, define it. Use examples and comparisons.
Step 3: Find the Gaps
Where did you get stuck, use vague words or skip a step? Those are gaps in your understanding. Go back to your textbook or notes and study just those parts.
Step 4: Simplify and Review
Rewrite your explanation more clearly and briefly. Add a simple analogy. Then try again tomorrow without notes.
Example: Photosynthesis
First try: “Plants make food from sunlight.” (Too vague.)
After filling gaps: “Plants take in carbon dioxide from the air and water from the soil. Using energy from sunlight, captured by a green substance called chlorophyll, they turn these into glucose (a sugar) for food and release oxygen. It’s like a kitchen powered by solar energy.”
Ways to Use It Alone
- Write it: on paper or in a notebook.
- Say it aloud: to a mirror or an empty chair.
- Record it: on your phone, then listen back.
- Draw it: add a simple diagram.
Why It Works
Explaining from memory is a form of retrieval practice, and asking “why?” and “how?” is called elaboration. Both are well-supported learning strategies; see UC San Diego on retrieval practice and the University of Edinburgh’s summary of six effective learning strategies.
Best Subjects for the Feynman Technique
| Good fit | Less ideal |
|---|---|
| Science concepts, economics, history causes, grammar rules | Pure memorisation, such as vocabulary lists (use flashcards instead) |

Final Thoughts
The Feynman Technique turns studying into explaining. Choose a concept, explain it simply, fix the gaps and simplify again. You can do it alone, anywhere, in just a few minutes.
