q3 · i? · review · r3

WWC systematic review of five studies of Cognitive Tutor® Algebra I meeting group design standards, totaling 12,182 students in 94 schools. The review found "positive and statistically significant in one study, positive and substantively important in a second study, and indeterminate in three other studies," yielding a mixed-effects rating with a medium-to-large extent of evidence.

"In the five studies that reported findings, the estimated impact of the intervention on outcomes in the algebra domain was positive and statistically significant in one study, positive and substantively important in a second study, and indeterminate in three other studies."
