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? Overall domain-general effects exceed domain-specific effects in grades 3 through 5, but by 8th grade domain-specific effects exceed domain-general effects and no overall differences are significant after 5th grade. → Geary David C. 2017

q3 · i? · associational · r2

Grade-by-grade contrasts from the longitudinal FDA model comparing summed domain-general and domain-specific beta estimates. Significant domain-general advantages in grades 4 (p = .014) and 5 (p = .023) give way to no significant differences after grade 5.

"There is a trend for larger overall domain-general than domain-specific effects in grade 3 (p = .067) and significant differences in grades 4 (p =.014) and 5 (p = .023). As shown in Figure 4, the overall domain-specific effect exceed the domain-general effect by 8th grade, but none of the overall differences are significant after 5th grade (ps > .117)."

Discussion¶

Learner Variables¶

Prior Knowledge — predictor: learners who differ on it differ in outcomes

The central executive component of working memory is the most important domain-general predictor of later-grade mathematics achievement — related
Fractions knowledge is a critical domain-specific predictor of mathematics achievement in later grades — related
The overall magnitude of domain-general effects on subsequent mathematics achievement remains constant across grades 2 to 8 — a narrower finding that bears on this claim
The overall importance of prior domain-specific mathematical knowledge for subsequent mathematics achievement increases across grades — a narrower finding that bears on this claim
Previous domain knowledge accounts for most of the variance in later achievement, considerably reducing the predictive impact of IQ and WM — related
