Technology and Child Development: Evidence from the One Laptop per Child Program
基于秘鲁农村318所小学的随机实验数据，评估“每个孩子一台笔记本电脑”项目对学业成绩和认知能力的影响，发现电脑使用增加但数学和语言成绩无显著改善，对一般认知能力有不确定的积极影响。
This paper presents results from a large-scale randomized evaluation of the One Laptop per Child program, using data collected after 15 months of implementation in 318 primary schools in rural Peru. The program increased the ratio of computers per student from 0.12 to 1.18 in treatment schools. This expansion in access translated into substantial increases in use of computers both at school and at home. No evidence is found of effects on test scores in math and language. There is some evidence, though inconclusive, about positive effects on general cognitive skills.
