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 combination of number sets, retrieval, decomposition, and number line measures explains substantively more variance in subsequent achievement (mean R2 = .822) than prior Numerical Operations scores (mean R2 = .682). → Geary David C. 2017

q3 · i? · associational · r2
Comparison of unadjusted FDA models fit to the longitudinal data: Model 2 (four mathematical cognition measures) versus Model 1 (prior Numerical Operations scores). The article reports mean R2 of .822 versus .682 across grades.
"in combination the mathematical cognition variables explain substantively more variation in subsequent achievement (mean R2 = .822, Table 2) than does Numerical Operations (mean R2 = .682)."
Discussion¶
Related Claims¶
- Fraction magnitude understanding, measured by number line estimation, predicts general mathematics achievement beyond fraction arithmetic skill in 5 of 6 Belgian, Chinese and U.S. grade samples, though not among Chinese 8th graders — related
- Number naming and number comparison are better predictors of kindergarten arithmetic than number line estimation — related
- Number line estimation and numerical magnitude comparison correlate with mathematics achievement (r = .24 to .44), with number line estimation more strongly related in older children — related
- Previous domain knowledge accounts for most of the variance in later achievement, considerably reducing the predictive impact of IQ and WM — related
