Mastery learning, the process by which students must demonstrate proficiency with a single topic before moving on, is well recognized as one of the most effective ways to learn. Yet many teachers struggle or remain unsure about how to implement it in a classroom setting.
This study evaluates a program to encourage greater mastery learning through technology and proactive continuous teacher support. Focusing on elementary and middle school mathematics, teachers received weekly coaching in how to use computer-assisted learning (CAL) to help students follow a customized roadmap of incremental progress.
Results from two field experiments indicate significant intent-to-treat effects on math performance of 0.12 to 0.22 standard deviations.
Further analysis indicates that these gains come from students in classrooms with at least an average of 35 minutes of practice per week. Teachers able to achieve high-dosage practice had a high degree of initial buy-in, a clear implementation strategy for when practice occurs, and a willingness to closely monitor progress and follow up with struggling students.
