The What Works Clearinghouse (WWC) has released an intervention report for Cognitive Tutor, a secondary mathematics curriculum that focuses on how students think about and learn maths. The programme can be implemented through a textbook, through adaptive software, or a combination of these activities.
The WWC identified six studies of Cognitive Tutor Algebra I and one study of Cognitive Tutor Geometry that met WWC research standards. The review showed the following:
Cognitive Tutor Algebra I has mixed effects on algebra achievement and no discernible effects on general mathematics achievement for secondary students.
Cognitive Tutor Geometry has potentially negative effects on geometry achievement for secondary students, with a small extent of evidence.
