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 i1 Students who used computer-based scaffolding within problem-based learning in STEM showed better learning performance than those who did not, with an overall effect of g = 0.385 (95% CrI 0.022 to 0.802). → Nam Ju Kim 2018

q3 · i1 · quant-synthesis · r2

Bayesian meta-analysis of 21 studies with 47 outcomes on computer-based scaffolding in PBL for STEM, using a random effects model and Hedges' g. The overall effect was "g = 0.385 (95% CrI = 0.022 to 0.802)", labeled small/moderate by Cohen (1988) in the discussion.

"The general effects of computer-based scaffolding compared to the group who did not receive any scaffolding was g = 0.385 (95% CrI = 0.022 to 0.802) based on 20,000 simulated iterations."
