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? Only Counting Recall (numerical working memory), not Listening Recall (verbal working memory), predicted decimal number line estimation accuracy. → Malone Amelia S. 2017
Evidence¶

q3 · i? · associational · r2
Regression for Decimal Number Line: the model accounted for 12.9% of the variance, F(6, 120)=2.97, p=.01. Counting Recall B=0.005, p=.024; Listening Recall p=.054 did not reach significance.
"WRAT-4 and Counting Recall predicted students' decimal number line estimation ability."
Discussion¶
Learner Variables¶
- Working Memory — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Language comprehension and numerical working memory predict comparing decimals to the one-half benchmark — related
- Symbolic exact addition is predicted by symbolic number line representation and the phonological loop, reflecting phonological storage of numerical information — related
- Symbolic approximate addition is predicted by nonsymbolic number line estimation, the VSSP and the CE, consistent with transcoding to the nonsymbolic code — related
- Nonsymbolic exact addition is predicted by the VSSP plus the CE and symbolic number line estimation, suggesting an alternate transcoding to the symbolic code — related
- Verbal working memory directly and positively predicts math performance in grades 3 and 4 — related
- Domain-general cognitive abilities predict at-risk fourth graders' decimal magnitude understanding — a broader claim this one bears on
