Students confuse processing fluency (it looks familiar) with mastery, and stop working. Four quick tasks (retrieve, explain, mix, transfer) let them see the gap themselves.
Tasks
- Retrieve: 60 seconds, notes closed, write what you remember.
- Explain: “How do you know?” / “Why does that work?” (self-explanation; Chi et al. 1994 circulatory-system study).
- Contrast: the correct answer beside a near-miss; how do you tell them apart?
- Transfer: a new text, context or variable after practice.
- Frame it as “evidence of what you don’t know yet”, not as a gotcha.
Research cited
Processing fluency (Alter & Oppenheimer 2009); retrieval vs restudy (Karpicke & Roediger 2008, Science); interleaved maths (Rohrer & Taylor 2007); retrieval and transfer (Butler 2010) (Claude: names inferred from the linked DOIs; verify).
Limits
- US K-12 framing; the citations are as printed in the article and weren’t checked against the primary papers.
Apply in my context (Claude)
- The contrast task is ideal for collocation and grammar near-misses (make/do a mistake; since/for). It’s a 2-minute warmer with strong diagnostic value, and it’s what Conti calls checking acquisition rather than performance.
