Subclaims¶

q3 i? The 16 pooled trials showed high heterogeneity in theoretical-score effects (I2 = 93%, P < 0.00001), attributed by the authors to differences in student educational levels, pharmacy disciplines, examination methods, and PBL implementation. → Zhou Jiyin 2016

q3 · i? · quant-synthesis · r3

Heterogeneity assessment across the 16 pooled randomized controlled trials using Cochran's Q and I2 statistics in RevMan 5.3. The analysis found "high heterogeneity (I2 = 93 %, P < 0.00001)", prompting use of a random-effects model for pooling.

"There was high heterogeneity (I2 = 93 %, P < 0.00001); thus, the random-effects model was used."

Discussion¶

Related Claims¶

• PBL is associated with higher theoretical examination scores than traditional lecture-based teaching in Chinese pharmacy education (SMD = 1.17) — related
• PBL produces higher examination scores than LBL in undergraduate pharmacology education (SMD = 2.03) — related
• PBL's examination-score advantage holds across student majors, publication years, and class sizes, but heterogeneity remains high in all subgroups — related
