Telementoring and Homeschooling During School Closures: a Randomised Experiment in Rural Bangladesh
在孟加拉国200个村庄开展随机实验，评估疫情期间电话学习支持（远程辅导）对小学生及其母亲的影响，发现受助儿童测试成绩提高35%，母亲每日家庭教育参与增加22分钟，且效果持续一年。
Abstract Using a randomised experiment in 200 Bangladeshi villages, we evaluate the impact of an over-the-phone learning support intervention (telementoring) among primary school children and their mothers during Covid-19 school closures. Post-intervention, treated children scored 35% higher on a standardised test, and the homeschooling involvement of treated mothers increased by 22 minutes per day (26%). We also found that the intervention forestalled treated children's learning losses. When we returned to the participants one year later, after schools briefly reopened, we found that the treatment effects had persisted. Academically weaker children benefited the most from the intervention that only cost USD20 per child.
