Have them teach it back
Preparing to teach reorganises knowledge in a way that preparing for a test doesn't. Give every student a reason to explain.

Students who teach material to someone else learn it better than students who study it expecting a test, and the act of actually explaining beats merely expecting to explain (Fiorella & Mayer, 2013). The catch, from peer tutoring research: most novice explainers slip into knowledge-telling, reciting rather than rebuilding (Roscoe & Chi, 2007). The fix is a listener who asks why.
In practice
- Frame tasks as teaching jobs: "Prepare to teach this to next year's class" changes how students read the material today.
- Arm the listener with two questions: "Why does that step work?" and "What would happen if you didn't?" That's what turns recital into rebuilding.
- Rotate roles inside one lesson. Teaching one problem then hearing one taught covers more ground than doing two.
- This pairs naturally with "Make them say it out loud": teach-back is the classroom-scale version of the sixty-second walkthrough.
Quick takeaway: the person doing the explaining is doing the learning.
