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.
q4 i3 Across 38 studies, the random-effects mean correlation between RAN and mathematics is r = .37 (95% CI [.32, .41]), with large heterogeneity. → Koponen 2017
Evidence¶
Koponen 2017¶
Koponen, T., Georgiou, G., Salmi, P., Leskinen, M., & Aro, M. (2017). A Meta-Analysis of the Relation Between RAN and Mathematics. Journal of Educational Psychology, 109(7), 977-992. https://doi.org/10.1037/edu0000182
q4 · i3 · quant-synthesis · r3
Systematic meta-analysis following PRISMA with random-effects REML estimation and robust variance estimation, pooling 151 correlations from 33 unique samples (7,135 participants). It reports "a significant correlation between RAN and mathematics (r = .37; 95% confidence interval [CI] .33–.42)" with large heterogeneity (Q(32) = 136.51, p < .001).
"The results showed a significant correlation between RAN and mathematics (r = .37; 95% confidence interval [CI] .33–.42) as well as a large heterogeneity of individual correlations."
Discussion¶
Learner Variables¶
- Processing Speed — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Metacognition is significantly positively correlated with math performance in adolescence (pooled r = .37) — related
- Morphological awareness is a significantly stronger correlate of adult reading comprehension than phonological awareness and RAN — related
