Rohrer, Doug; Dedrick, Robert F.; Hartwig, Marissa K.; Cheung, Chi-Ngai – Grantee Submission, 2019
We report the results of a pre-registered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no two consecutive problems require the same…

Rohrer, Doug; Dedrick, Robert F.; Stershic, Sandra – Journal of Educational Psychology, 2015
A typical mathematics assignment consists primarily of practice problems requiring the strategy introduced in the immediately preceding lesson (e.g., a dozen problems that are solved by using the Pythagorean theorem). This means that students know which strategy is needed to solve each problem before they read the problem. In an alternative…
