q3 i? Across all five outcome domains, heterogeneity exceeded 90%, and most subgroup analyses by teaching format, learner group, and course type did not explain the variability. → Wu Yaqiu 2026

Evidence¶

Wu Yaqiu 2026¶

Wu Yaqiu, Cheng Meixiong. (2026). Effectiveness of the flipped classroom in medical education: a systematic review and meta-analysis. BMC Medical Education. https://doi.org/10.1186/s12909-026-09526-8

q3 · i? · quant-synthesis · r2

Synthesis-wide finding from the review's discussion: heterogeneity exceeded I² 90% across all five outcome domains, and prespecified subgroup analyses mostly failed to explain it; the authors list instructional design granularity, facilitation skills, implementation fidelity, assessment validity, and prior study habits as potential effect modifiers.

"A major finding of this review was the consistently high heterogeneity across outcomes (I² > 90%). Although prespecified subgroup analyses by teaching format, learner group, and course type were conducted, most did not explain the observed variability"

Discussion¶

Related Claims¶

• Effect sizes across included studies show high heterogeneity (all I² above 75%) — a broader claim this one bears on
• Effect sizes across studies show substantial heterogeneity, with wide prediction intervals spanning large negative to large positive true effects — a broader claim this one bears on
• Effect sizes across the included studies are highly heterogeneous (I² = 91.37%), indicating moderating factors — a broader claim this one bears on
• Included flipped classroom studies show substantial heterogeneity, requiring a random-effects model — related
• Flipped classrooms are associated with improved self-directed learning ability in medical education (pooled SMD = 2.54), but extreme heterogeneity precludes interpreting this as a uniform effect — a narrower finding that bears on this claim
• Flipped classrooms are associated with higher learner satisfaction in medical education (pooled SMD = 0.69), with residents showing larger improvement than undergraduates (SMD 1.69 vs 0.37) — a narrower finding that bears on this claim
• Gamified flipped classroom/animation knowledge effects are inconclusive due to few studies and extreme heterogeneity — a narrower finding that bears on this claim
• Flipped classrooms are associated with improved procedural/technical skills in medical education (pooled SMD = 1.80), with larger effects among residents and in theoretical-course settings — a narrower finding that bears on this claim
