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.

q2 i3 Students demonstrated stronger self-learning abilities with 3D + PBL teaching compared to LBL teaching (SMD = 1.28, 95% CI: 0.96–1.60, P < 0.00001). → Li Ting 2025

q2 · i3 · quant-synthesis · r2

Meta-analysis of four RCTs (N = 186) with a fixed-effect model found "students demonstrated stronger self-learning abilities with 3D + PBL teaching compared to LBL teaching". GRADE certainty was very low; no significant heterogeneity was observed (I2 = 0%).

"The meta-analysis found that students demonstrated stronger self-learning abilities with 3D + PBL teaching compared to LBL teaching (SMD = 1.28, 95% CI: 0.96–1.60, P < 0.00001; see Figure S1)."
