Teach It Back
Exercise 3: Teach It Back
Layers Used: Layer 3 (Live Defence)
What You Do
Deliver a 10-minute teaching session to your peers on what you learned. The session is followed by 5 minutes of questions — questions that will go beyond what you prepared. No AI access during the session.
Record yourself teaching the topic for 10 minutes (audio or video). Then prompt AI: "You are a student who knows nothing about [domain]. You just heard a 10-minute teaching session. Ask me 5 follow-up questions — mix basic comprehension with harder questions that test true understanding. Wait for my response to each before asking the next." Conduct the full Q&A and submit the transcript.
Your teaching session outline or slides (may use AI to help prepare, but document what you used). Peer feedback forms rating: clarity of explanation (1-10), depth of understanding demonstrated (1-10), ability to answer unexpected questions (1-10), and engagement (1-10). A list of every question you were asked, whether you could answer it, and for unanswered questions — your honest assessment of whether you genuinely did not know or knew but could not articulate.
I just completed a teach-back session after learning a domain from scratch in 72 hours. Below are my teaching materials, the questions I was asked, and my peer feedback. Please:
(1) Based on the questions I could not answer, what are the key gaps in my understanding? (2) For the questions I answered poorly, suggest better explanations I could have given. (3) Rate my learning efficiency: given 72 hours, did I reach an appropriate depth, or should I have gone deeper in fewer areas? (4) Based on my peer feedback scores, what should I prioritize improving -- clarity, depth, spontaneous response, or engagement? (5) Create a "Next 20 Hours" learning plan for me -- if I had 20 more hours, what should I study to fill my most critical gaps?

Finally, complete the Thinking Score Card for this exercise: Independent Thinking (1-10), Critical Evaluation (1-10), Reasoning Depth (1-10), Originality (1-10), Self-Awareness (1-10). For each score, give a one-sentence justification.
Discuss with an AI. Question your scores.
Come back when you have your BEST evaluation.
What This Teaches You
You learn that teaching is the ultimate test of understanding. If you can explain something to someone who knows nothing about it, you have truly learned it. If you collapse under unexpected questions, you memorized without understanding. The AI-generated "Next 20 Hours" plan gives you a precise roadmap for continued learning.
