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? Concept formation was the only cognitive predictor of accuracy on the Decimal Equivalency task beyond incoming calculation skill. → Malone Amelia S. 2017

Evidence¶

q3 · i? · associational · r2

Regression for Decimal Equivalency: model accounted for 16.3% of variance, F(6, 120)=3.89, p=.001. Concept Formation B=0.059, p=.022; all other cognitive predictors non-significant.

"WRAT-4 and Concept Formation predicted students' accuracy in assessing whether magnitude statements were true or false."

Discussion¶

Learner Variables¶

General Cognitive Ability — predictor: learners who differ on it differ in outcomes
