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 i0 Across 76 treatment-control studies, collaborative models of instruction produced a mean effect of g = 0.11 (95% CI [0.035, 0.184]) on academic achievement relative to single-taught controls. → Vembye 2022

q3 · i0 · quant-synthesis · r3

Meta-analysis of 76 treatment and control group studies using the CHE-RVE model with robust variance estimation; 280 short-term effect sizes, 82% pretest-adjusted. The review reports a "moderate, positive, and statistically signif- icant mean effect" of g = 0.11 with CI [0.035, 0.184].

"We found a moderate, positive, and statistically signif- icant mean effect of 𝑔̅ = 0.11, 95% CI[0.035, 0.184] of collaborative instruction compared to sin- gle-taught controls, using the correlated-hierarchical effects (CHE-RVE) model."
