Subclaims¶

q3 i? At the beginning of preschool, dropping nonverbal calculation from the best Bayes model yielded a model only 3.4% as probable, and dropping give-a-number 0.4% as probable, indicating substantial evidence for both predictors. → Moore 2016

Evidence¶

Moore 2016¶

Moore, A. M., vanMarle, K., & Geary, D. C. (2016). Kindergartners' Fluent Processing of Symbolic Numerical Magnitude is Predicted by Their Cardinal Knowledge and Implicit Understanding of Arithmetic Two Years Earlier.

q3 · i? · associational · r2

Bayes factor model comparison over beginning-of-preschool quantitative predictors of kindergarten number sets performance in 112 children; the best model included give-a-number, nonverbal calculation, and point-to-x, and excluding nonverbal calculation left a model "3.4% as probable".

"there is substantial evidence for the importance of nonverbal calculation (3.4% as probable without this predictor) and give-a-number (0.4%)."

Discussion¶

Learner Variables¶

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