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? Classrooms randomly assigned to the revised textbook with correct and incorrect worked examples and self-explanation prompts showed significantly greater probabilistic reasoning gains at posttest than control classrooms. → Begolli 2021

q3 · i? · causal · r2

Cluster-randomized classroom experiment with 220 seventh-graders in 10 classrooms (5 treatment, 5 control) using OLS regression with cluster sandwich estimator. The treatment predictor was significant: "bTreatment = 0.85, SE = 0.31, t = 2.78, p = 0.021". The final model explained 29.4% of variance.

"the students who used the worked example revised textbook improved significantly more in Probabilistic Reasoning scores than students who used the standard CMP textbook, confirmed by a significant treatment predictor (bTreatment = 0.85, SE = 0.31, t = 2.78, p = 0.021)."
