Rohrer, Doug; Dedrick, Robert F.; Hartwig, Marissa K. – Educational Psychology Review, 2020
A typical mathematics assignment consists of a block of problems devoted to the same topic, yet several classroom-based randomized controlled trials have found that students obtain higher test scores when most practice problems are mixed with different kinds of problems--a format known as interleaved practice. Interleaving prevents students from…

Rohrer, Doug; Hartwig, Marissa K. – Grantee Submission, 2020
A typical mathematics assignment consists of one or two dozen practice problems relating to the same skill or concept, yet empirical evidence suggests that there is little or no long-term benefit from working more than a few problems of the same kind in immediate succession. Alternatively, randomized experiments in the laboratory and classroom…
