Evaluating Adaptive, Computer-Based Mathematics Tutoring Systems A Math Improvement and Feasibility Study

Abstract
This study evaluated two off-the-shelf, adaptive and computer-based mathematics tutoring systems that teach algebra and other foundational math skills. Thirty high school algebra students that failed to pass algebra in the previous semester were randomly assigned in equal proportions to work with Carnegie Learning’s Cognitive Tutor or ALEKS algebra course product. Using the tutoring system exclusively, the students completed a 4-hour-a-day, 14 day summer school high school algebra class for credit. The results revealed that both tutoring systems produced very large learning gains, on the magnitude of a two-sigma effect, on measures of arithmetic and algebra knowledge.
