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? Nonsymbolic magnitude comparison was moderately predictive of future mathematics achievement only in kindergarten, not across later years. → Xenidou-Dervou 2017
Evidence¶
Xenidou-Dervou 2017¶
Xenidou-Dervou, I., Molenaar, D., Ansari, D., van der Schoot, M., & van Lieshout, E.C.D.M. (2017). Nonsymbolic and symbolic magnitude comparison skills as longitudinal predictors of mathematical achievement. Learning and Instruction, 50, 1-13. https://doi.org/10.1016/j.learninstruc.2016.11.001
q3 · i? · associational · r2
In the same three-wave longitudinal sample assessed in kindergarten, grade 1 and grade 2, the abstract states "Nonsymbolic comparison was moderately predictive only in kindergarten." No effect size is printed in the available text.
"Nonsymbolic comparison was moderately predictive only in kindergarten."
Discussion¶
Learner Variables¶
- Number Sense — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Symbolic and nonsymbolic magnitude comparison follow different developmental trajectories, with symbolic comparison undergoing larger developmental improvements between kindergarten and grade 2 — related
- Both nonsymbolic and symbolic magnitude comparison skills longitudinally predict mathematical achievement above and beyond IQ and working memory — related
- Symbolic magnitude comparison is a robust and consistent longitudinal predictor of children's future mathematical achievement across kindergarten, grade 1 and grade 2 — related
- Symbolic magnitude comparison is a stronger longitudinal predictor of mathematical achievement than nonsymbolic comparison — 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
