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 Pooling the five experiments, the overall effect of jigsaw on learning outcomes was essentially zero and did not include the hypothesized d = 0.40. → Arnaud Stanczak 2022

q3 · i0 · causal · r3

Internal mini meta-analysis combining the five experiments' estimates, conducted following Goh et al. recommendations to synthesize the article's own studies. The pooled estimate was ES = 0.00 with 95% CI [-0.10, 0.09], showing the intervention "did not produce the expected positive effects on learning".

"Internal meta-analytic estimates (ES = 0.00, 95% CI [-0.10, 0.09]) showed that, overall, the jigsaw intervention did not produce the expected positive effects on learning."
