q3 · i2 · causal · r2

Preregistered counterbalanced within-subjects classroom experiment in two lecture sections of an introductory physics course; 290 and 286 students completed all homework in Stages 1 and 2. The article reports "d = 0.40" in Stage 1 and "d = 0.91" in Stage 2, with interleaving improving median test scores over blocking by 50% and 125%.

"Interleaving yielded higher criterial test scores than blocking in Stage 1, d = 0.40, 95% CI [0.17, 0.65], t(288) = 3.41, p = 0.0008, and in Stage 2, d = 0.91, 95% CI [0.66, 1.20], t(284) = 7.68, p < 0.0001."

Discussion¶

Related Claims¶

• Students perform worse on interleaved homework than blocked homework and misjudge its learning value — reports the opposite
• Interleaving benefits on criterial tests cannot be attributed to increased study time — related
• Interleaving benefits were not detected on high-stakes midterm exams taken after cramming — related
• Interleaving improves both long-term memory for formulas and exact answer correctness on criterial tests, with a smaller benefit for correctness — related
• Interleaved practice yields better category learning than blocked practice, and students who choose interleaved practice outperform those who choose blocked practice on novel materials — related
• At a 1-day test delay, interleaved practice yields a moderate benefit over blocked practice (d = 0.42) — related
• When exemplars are already interleaved, larger temporal spacing between same-category exemplars yields better inductive learning than smaller spacing — related
• Interleaved practice produces higher mathematics test scores than blocked practice in a classroom experiment — related
• The experiment used a counterbalanced crossover design in which the same practice problems were rearranged into blocked and interleaved versions — related
