Results from a randomized efficacy trial of cognitive tutor geometry

This study aims to help address a need for information about efficacious mathematics curriculum and instruction at the high school level. Data from national and international studies, including the National Assessment of Educational Progress (NAEP), show very low mathematics proficiency rates for high school students. Many educators recognize a need to improve mathematics achievement through interventions such as new curriculum materials or instructional approaches, however they lack rigorous evidence on efficacy. By providing such information, this study can help guide educators in selecting the most promising materials. The purpose of the study is to evaluate the efficacy of the Cognitive Tutor Geometry curriculum by Carnegie Learning Inc., using randomized controlled trials.
