| Field Paper Abstract | Before | After This study investigates the effectiveness of a globally popular method of self-learning at the right level in improving learning outcomes—the cognitive and noncognitive abilities of disadvantaged students—in a developing country, Bangladesh. Using a randomized controlled trial design, we find substantial improvements in cognitive abilities measured by math test scores and catch-up effects in terms of noncognitive abilities or personality traits measured through a self-esteem scale. Moreover, our study is the first to use alternative cognitive ability measures, that is, time reduction as well as time-adjusted test score, which are critical dimensions of cognitive development. Subsequently, we investigate the long-term effects using students’ math results of the national-level exam. We find a reasonable longer-term impact on cognitive abilities 20 months after the intervention for younger students. Our estimates indicate that the program’s benefits exceed its costs. |

| Field Paper Abstract | Before | After This study investigates the effects of speed competition in classrooms on young pupils' learning outcomes. To examine how faster peers' speed affects slower pupils' speed and learning, we employ students' daily progress data in a self-learning programme at BRAC primary schools in Bangladesh. The programme's unique setting allows us to address the reflection problem reasonably well. While speed competition could generate negative consequences, our results show overall positive peer effects on problem-solving time and scores. The effects are stronger among peers with similar abilities, without negatively affecting others. Our results show efficiency gains from non-market competition in education and learning. |
