q3 i? At the end of preschool, dropping point-to-x from the best Bayes model left a model only .3% as probable, and it remained significant for overall, nonsymbolic, and mixed item sets even with mathematics achievement controlled. → Moore 2016

q3 · i? · associational · r2

Bayes factor analysis of end-of-preschool predictors in the same longitudinal sample: the best model included nonverbal calculation, point-to-x, and numeral recognition, but excluding point-to-x left a model only ".3% as probable", marking it as the critical predictor.

"Dropping each variable from the top model provided substantial evidence for the importance of point-to-x (.3% as probable without this predictor), and only weak evidence for nonverbal calculation and numeral recognition."

Discussion¶

Learner Variables¶

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