Abstract
This study provides evidence on the relative effectiveness of computer-assisted learning (CAL) software and traditional teaching. Based on a field experiment in Salvadoran primary schools, we evaluate three interventions that aim to improve learning in mathematics: (i) additional teacher-led classes, (ii) additional CAL classes monitored by a supervisor, and (iii) additional CAL classes instructed by a teacher. We find that CAL lessons lead to larger learning gains and are less sensitive to class size as well as student ability than teacher-centered classes. Our results highlight the value of CAL in an environment with heterogeneous classes and poorly qualified teachers.
期刊介绍:
Since 1983, the Journal of Labor Economics has presented international research that examines issues affecting the economy as well as social and private behavior. The Journal publishes both theoretical and applied research results relating to the U.S. and international data. And its contributors investigate various aspects of labor economics, including supply and demand of labor services, personnel economics, distribution of income, unions and collective bargaining, applied and policy issues in labor economics, and labor markets and demographics.
