q3 · i? · associational · r2

Longitudinal study assessing a large sample in kindergarten, grade 1 and grade 2 on magnitude comparison measures, IQ and working memory. The abstract reports that "Symbolic comparison, however, was a robust and consistent predictor of future mathematics across all three years." No effect size is printed in the available text.

"Symbolic comparison, however, was a robust and consistent predictor of future mathematics across all three years."

Discussion¶

Learner Variables¶

• Number Sense — predictor: learners who differ on it differ in outcomes
