Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i3 Students taught with PBL-CBL performed significantly higher on practical skills scores than those taught with LBL (SMD = 1.53). → Xiong Xianghua 2025

q3 · i3 · quant-synthesis · r2
Meta-analysis of 12 studies (760 students) on practical skills scores. Pooled estimate favored PBL-CBL: "SMD = 1.53, 95% CI: 1.07-2.00, P < 0.0001" with high heterogeneity (I2 = 87%).
"The PBL-CBL group was found to perform significantly higher than the LBL group in practical skills scores (SMD = 1.53, 95% CI: 1.07-2.00, P < 0.0001, I2 = 87%, Fig. 8)"
