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? Different small classes showed low achievement with low non-symbolic approximation only, low achievement with low symbolic approximation only, or average achievement with low non-symbolic approximation. → Hart 2015
Evidence¶
Hart 2015¶
Hart, Sara A.; Logan, Jessica A.R.; Thompson, Lee; Kovas, Yulia; McLoughlin, Gráinne; & Petrill, Stephen A. (2015). A latent profile analysis of math achievement, numerosity, and math anxiety in twins. Journal of Educational Psychology. https://doi.org/10.1037/edu0000045
q3 · i? · associational · r2
Three small LPA classes (classes 1, 2, 3; n = 18, 17, 29) each showed a different combination of numerosity deficit and achievement level, indicating the numerosity-achievement link is not uniform across struggling children.
"Some children showed low achievement with low non-symbolic number approximation only, others showed low achievement with low symbolic number approximation only, and finally some children showed average achievement with low non-symbolic number approximation."
Discussion¶
Related Claims¶
- Anxious low achievers: a large class of children shows low math achievement and the highest math anxiety despite average numerosity — related
- Latent profile analysis of 12-year-old twins identifies five distinct profiles of math achievement, numerosity, and math anxiety — a broader claim this one bears on
- Familial resemblance in profile membership appears only for high performers; struggling profiles show child-specific influences — related
