q3 · i3 · quant-synthesis · r3
Meta-analysis of 30 comparative studies involving 4119 participants reporting examination scores, pooled with a random-effects model due to heterogeneity (I2 = 98%). The pooled effect size favored PBL: "SMD = 2.03, 95% CI [1.53, 2.53], P < .00001".
"Students receiving the PBL method in undergraduate pharmacology education tended to achieve higher examination scores in objective tests than those receiving the traditional LBL method (SMD = 2.03, 95% CI [1.53, 2.53], P < .00001)."
Discussion¶
Related Claims¶
- CBL is the highest-ranked strategy for enhancing medical students' theoretical test scores, with CBL, PBL, SBL and FC each significantly outperforming LBL — a broader claim this one bears on
- PBL's examination-score advantage holds across student majors, publication years, and class sizes, but heterogeneity remains high in all subgroups — a broader claim this one bears on
- In the RCT, PBL students obtained significantly better final exam grades than LBL students, but the meta-analysis found no significant final-exam difference — related
