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 i? Pure PBL (0.950), technology-supported (1.100), thinking-oriented (0.951), paper-based (1.665), and constructivist-assisted PBL (1.267) all showed high effect sizes with no significant between-group difference (Q = 0.657, p > 0.05). → Ufuk Uluçınar 2022

q3 · i? · quant-synthesis · r2

Moderator analysis by instructional variation across the 55 datasets (random effects model): 42 pure PBL, 4 technology-supported, 3 thinking-oriented, 2 paper-based, 4 constructivist-assisted. Paper-based PBL's confidence interval was very wide (−2.056 to 5.333).

"The results also show no significant difference between the studies included in the meta-analysis by instructional variations with PBL (Q=0.657; Ρ > 0.05)."
