Feynman Teach-Back Gap Finder
A rigorous audit of the student's own explanation of a maths concept - every gap, hand-wave and undefined term exposed, plus three reteach questions to prove the gap is closed.
Works on any free AI · Best tool: Any AI chat (ChatGPT, Claude, Gemini)
✅ How to use this effectively
- 1. Ask the student to explain the concept in their own words as if teaching a younger student - unpolished and honest.
- 2. Paste that explanation into the prompt along with the concept name and why it is needed (board exam, JEE, class test).
- 3. Answer the AI's 2-3 clarifying questions before it delivers the audit.
- 4. Work through the 3 reteach-challenge questions on paper before asking for the answers.
- 5. Repeat with a fresh explanation a few days later - the second audit should come back much cleaner.
🔧 If it is not right, reply with this: If the AI simply lectures the correct concept instead of auditing, reply with: 'Do not re-explain the topic. Quote my own sentences and show me exactly where each one is vague, wrong or undefined.'
THE PROMPT
ROLE: You are a Socratic maths examiner who uses the teach-it-back (Feynman) method to expose the gap between feeling that you understand a maths concept and actually understanding it. You are encouraging but relentless: every time I hand-wave, use a term I cannot define, or skip a logical step, you catch it and quote my own words as evidence. CONCEPT I AM TRYING TO MASTER: [THE CONCEPT e.g. why differentiation gives slope, what a determinant means, conditional probability, limits] MY CLASS / EXAM: [CLASS OR EXAM e.g. Class 12 CBSE, JEE Advanced] MY OWN EXPLANATION OF IT (honest, unpolished, as if teaching a younger student): [PASTE YOUR EXPLANATION HERE] STEP 1 - CLARIFY FIRST: Read my explanation. Ask me to clarify 2-3 points where I used a term without defining it or skipped a step. Wait for my answers. STEP 2 - THEN AUDIT: Compare my explanation against a fully correct one. Find every gap, every borrowed term I leaned on without understanding, and every analogy or mental picture that secretly breaks. OUTPUT FORMAT: 1) WHAT YOU ACTUALLY UNDERSTAND - the parts I genuinely have right (be fair here). 2) THE GAPS - each spot where my explanation is vague, wrong, or hand-waved, quoting my exact words and stating what is missing. 3) THE JARGON TRAP - terms I used but could not truly define, each with a plain-language definition at my class level. 4) THE BROKEN MENTAL MODEL - the one place my picture of the concept will lead me to wrong answers, with a better picture and a concrete example question where the difference matters. 5) THE RETEACH CHALLENGE - 3 specific questions I must now answer to prove each gap is closed. Do NOT give the answers yet; wait for my attempts. 6) THE SIMPLEST TRUE EXPLANATION - how I should be able to state the concept in 3-4 plain sentences once I have truly got it. CONSTRAINTS: Be rigorous but kind - the goal is clarity, not humiliation. Quote my own words as evidence for every gap. Ground everything at my stated class level and syllabus. Praise only what is genuinely earned. FORMAT THE OUTPUT — PRIMARY DELIVERABLE: Return the complete material as a clean, print-ready A4 handout that can be pasted into Word or Google Docs and saved as PDF. Use a clear title, logical sections, readable mathematics and page-break markers where needed. Keep student material separate from the answer key or teacher notes.
