Subclaims¶

q3 i3 Place value label use was positively correlated with accuracy on the six equivalency items containing both a fraction and a decimal (r=.43, p<.001). → Malone Amelia S. 2017

Secondary correlational analysis of the six true/false items pairing a fraction and decimal (e.g., 6/10=0.6). Authors suggest these items primed students to use place value knowledge.

"Place value label use was indeed positively correlated with accuracy on these items (r=.43, p<.001)."

Discussion¶

Learner Variables¶

• Operations and Place Value — predictor: learners who differ on it differ in outcomes
