Interactive Learning Effects of Preparing to Teach and Teaching: a Meta-Analytic Approach

Which beliefs it touches

• C15 Learning by teaching pushes against it

  Meta-analysis of 39 studies: teaching after studying with teaching expectancy g = 0.48, but teaching after studying without expecting to teach g = −0.02 [−0.14, 0.11]; actually teaching added g = 0.38 over preparing only (14 studies). C15's wording does not require studying with teaching expectancy; delay of the outcomes not stated in the abstract. Queued for the nightly run, not a verdict.
