Can Mobile Phones Improve Learning? Evidence from a Field Experiment in Niger
在尼日尔成人教育项目中，学习使用简单手机的学生在数学测试中成绩更高，且效果在课程结束七个月后仍持续，表明信息技术可改善农村教育成果。
The returns to educational investments hinge on whether such investments can improve the quality and persistence of educational gains. We report the results from a randomized evaluation of an adult education program in Niger, in which some students learned how to use simple mobile phones (Project ABC). Students in ABC villages achieved test scores that were 0.19–0.26 standard deviations higher than those in standard adult education classes, and standardized math test scores remained higher seven months after the end of classes. These results suggest that simple information technology can be harnessed to improve educational outcomes among rural populations.
