q3 · i0 · quant-synthesis · r3

Meta-analysis of 35 intervention studies (7701 students aged 6–16) using Robust Variance Estimation; the RVE model found "a small and statistically significant effect (g = 0.14, 95% CI [0.002, 0.288], t(11) = 2.23, p = 0.04)" for working memory.

"The RVE model also presented a small and statistically significant effect (g = 0.14, 95% CI [0.002, 0.288], t(11) = 2.23, p = 0.04). Among cognitive outcomes, working memory demonstrated the most consistent evidence of potential benefit from active breaks."

• Classroom active breaks show no statistically significant effect on attention in schoolchildren — related
• Classroom active breaks show no statistically significant effect on inhibitory control in schoolchildren — related
• Pooled active-break effect estimates are robust to sensitivity analyses varying within-study correlation and excluding individual studies — related
• Classroom-based physical activity interventions improve attention and/or on-task behavior in most reviewed studies of schoolchildren aged 4–18 — related
• Moderate-to-vigorous intensity active breaks are associated with slightly greater working-memory improvements than moderate intensity, in exploratory meta-regression — a narrower finding that bears on this claim
• Effects of active breaks on mathematical achievement are small and lose significance under Robust Variance Estimation — related
• Classroom active breaks show no reliable effect on mathematical fluency — related
• The pooled association is robust to dependence, baseline-adjustment, risk-of-bias, and effect-size-derivation sensitivity analyses — related
