Abstract

We study the impacts of the program Khan Academy in Schools using a randomized control trial in Brazilian primary public schools. Once a week, teachers would take their students to the school's computer lab and teach using the Khan Academy platform, instead of their standard math classes. We find positive effects of the program on measures of attitudes towards math, which were not translated to a positive average treatment effect on students' math proficiency. We also explore treatment heterogeneity by quality of implementation, suggesting that the program can have positive effects when there are no infrastructure problems and when the implementation modality is based on one computer per student. These results highlight the implementation challenges associated with educational tech-interventions in developing countries.
