Field Paper Abstract | Before | After This paper analyzes the impact of technology use on student math learning using experimental data from Brazil. The technology is a software tool designed for elementary school students to learn and practice arithmetic. Contrary to most interventions in which computer-aided instruction extends the school day, students played the game during class time for about 2 months. First, second, and third graders who used the software increased their score on a math test by 0.56 s.d. in the short term ( just after the intervention) and by 0.17 s.d. in the medium term (1 year after the end of the intervention). |
