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? WASI Vocabulary and Counting Recall uniquely predicted accuracy comparing decimals to the fraction 1/2 benchmark, controlling for other predictors. → Malone Amelia S. 2017

q3 · i? · associational · r2

Regression for the Compare to 1/2 outcome: predictors together accounted for 13.2% of the variance, F(6, 120)=3.03, p=.009. Vocabulary (B=0.062, p=.009) and Counting Recall (B=0.078, p=.038) were significant predictors.

"WASI Vocabulary and Counting Recall predicted students' ability to accurately compare a decimal to one-half."

Discussion¶

Learner Variables¶

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

Numerical working memory predicts decimal number line estimation accuracy — related
Vocabulary scores predicted executive-loaded non-verbal working memory scores beyond age and non-verbal reasoning — related
Domain-general cognitive abilities predict at-risk fourth graders' decimal magnitude understanding — a broader claim this one bears on
Cognitive abilities correlate with decimal label use patterns — related
In e-learning text comprehension, higher working memory and lower self-reported navigation behavior predict better comprehension — related
