Cognitive Tutor
About the Intervention
Cognitive Tutor is a secondary mathematics curriculum developed by Carnegie Learning that focuses on how students think about and learn mathematics in grades 8-13. The curriculum can be implemented using a textbook, adaptive software, or a combination of both. In a blended implementation, students spend three periods per week using textbooks for collaborative classroom activities where they work cooperatively to solve problems, participate in investigations, and propose and compare solutions. Two periods per week are spent in computer labs using adaptive software where students learn at their own pace. The curriculum uses a pedagogical approach where teachers facilitate student learning as students acquire and apply new information and discuss their work. Multiple learning styles are accommodated through real world problems, peer review, step-by-step demonstrations, hands-on tools including manipulatives and technology, graphic representations, and classroom discussions. Teachers receive implementation guides, assessments, professional development, and classroom management tools. Students receive texts, personalized instruction using the software system, and supplemental materials such as assignments and skills practice exercises. Teachers implementing the curriculum receive 3-4 days of professional development training led by consultants from the curriculum developer.
