Implication

Randomized trial demonstrates higher test scores with interleaved practice versus blocked practice in seventh-grade students, indicating this instructional approach is effective and feasible.

Key Points

To evaluate the efficacy and real-world feasibility of an interleaved mathematics practice intervention compared to standard blocked practice in middle school classrooms.
Preregistered cluster randomized controlled trial involving 54 seventh-grade mathematics classes conducted in a naturalistic setting over 4 months.
Classes periodically completed either interleaved assignments (where no two consecutive problems used the same strategy) or blocked assignments, followed by a shared interleaved review assignment.
Students completed an unannounced retention test 1 month later, and teachers completed an anonymous feasibility survey prior to learning the study outcomes.
Students in the interleaved practice group significantly outperformed the blocked practice group on the unannounced retention test (61% vs. 38%, d = 0.83).
Teachers successfully administered the intervention without special training and reported favorable support for interleaved practice.
