What does the research say about game-based learning?
A 2020 meta-analysis of 27 studies found that game-based learning produced a mean retention gain of +27% over traditional review (Clark, Tanner-Smith, & Killingsworth). The mechanism: retrieval practice + social motivation + immediate feedback.
Family Feud-style games hit all three: students retrieve answers from memory, social stakes amplify motivation, and the host reveal provides immediate corrective feedback.
