q2 · i? · review · r3

The WWC's synthesis of the Elementary School Mathematics evidence base: of 11 identified studies, only Wang and Woodworth (2011) met evidence standards, so the extent of evidence is "Small — One study that included 557 students in three schools reported evidence of effectiveness."

"Thus, for the mathematics achievement domain, the study showed a statistically significant positive effect. This results in a rating of potentially positive effects, with a small extent of evidence."
