Work through the levels in order. Type your answer and press Check — open the worked solution if you get stuck. Answers like -6, 3/4 or 0.25 are typed exactly as shown.
Level 1 · Warm-up
1 How many steps does the Feynman technique have?
Show worked solution
Four — write, mark, return to the source for the marked gaps, then rewrite and simplify. Repeat.
2 You explain a topic aloud with your notes open in front of you. What are you actually doing?
Show worked solution
Reading aloud. With the notes open you never retrieve, so no gaps are exposed. Close the book.
Level 2 · Core
3 Your second Feynman draft is longer and more technical than your first. What has gone wrong?
Show worked solution
Step 4 simplifies. A longer, more technical draft means you copied the repair instead of absorbing it.
4 Which is a legitimate use of a technical term in a Feynman explanation?
Show worked solution
Terms are earned: plain explanation first, then the proper word back in. Jargon is a tool for speed, not a cover for a gap.
Level 3 · Challenge
5 A student can answer every recall question on a topic but cannot produce a two-minute plain explanation of it. What does this reveal?
Show worked solution
Explaining needs ordering and connecting, not just retrieving. Isolated facts pass a quiz and fail an extended-response question.
6 Which self-explanation prompt most directly builds the links that make recall easier later?
Show worked solution
The connection prompt. Links are the paths recall travels along — an isolated fact has no route back to it.
