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? The reading fluency construct significantly predicted multiplication skill, and working memory showed no significant association in the reading model, in contrast to the arithmetic models. → Rautiainen 2026

q3 · i? · associational · r2
Reading fluency contrast model in the longitudinal SEM study (n = 207), designed to probe domain-specificity because reading shares timed performance and retrieval demands but lacks numerical content. The article notes the reading construct consumed more covariance (β = .45) than addition (β = .30) and subtraction (β = .28); R2 = .33 (R2 = .40 prior residualization).
"Remarkably, for working memory, no significant association existed; this pathway emerged in the arithmetic models in contrast to the baseline model. However, the reading fluency construct consumes more covariance (β = .45) than addition (β = .30) and subtraction"
Discussion¶
Learner Variables¶
- Arithmetic Fact Retrieval — predictor: learners who differ on it differ in outcomes
- Long-Term Memory — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Addition fluency captures more shared variance with serial retrieval fluency than subtraction fluency does — related
- Addition fluency strongly predicts third-grade multiplication fluency, and a significant working memory association emerges after controlling for addition fluency — related
- Numerical abilities and serial retrieval fluency predict third-grade multiplication fluency, while working memory shows no significant association in the baseline model — related
- Inhibition does not uniquely predict arithmetic fact retrieval above numerical magnitude processing — related
- Subtraction fluency predicts third-grade multiplication fluency on par with addition fluency, with a similar emergent working memory association — related
