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 Meta-regressions revealed that effect sizes based on mathematics tests were significantly larger than effect sizes based on reading tests, and QES showed significantly larger effect sizes than RCTs. → Dietrichson J 2020

q3 · i1 · quant-synthesis · r3

Meta-regression across instructional methods and moderators. Maths-test effect sizes averaged ES = 0.34 [0.169, 0.502] versus reading-domain effects of 0.14–0.22; QES effects exceeded RCT effects, a design-related moderator the review flags.

"Including all instructional methods and moderators without missing observations in meta‐regressions revealed that effect sizes based on mathematics tests were significantly larger than effect sizes based on reading tests, and QES showed significantly larger effect sizes than RCTs."
