Abstract

ABSTRACT This paper examines the external validity of health intervention by comparing the impacts of providing free eyeglasses on the educational performance of nearsighted children in two settings: rural public schools in Western China and urban private migrant schools in Eastern China. The intervention significantly improves educational outcomes by 0.14 standard deviations in math in rural public schools but not in private migrant schools. The difference in measured impacts is due in part to lower quality schooling in migrant schools in Eastern China. Our findings show that only when school is providing a quality education, health interventions might increase student learnings.

摘要:本文通过比较西部农村公立学校和东部城市民办农民工子弟学校提供免费眼镜对近视儿童学习成绩的影响,检验健康干预的外部效度。干预显著提高农村公立学校数学成绩0.14个标准差,但对民办农民工学校没有显著改善。测量影响的差异部分是由于中国东部农民工学校的教育质量较低。我们的研究结果表明,只有当学校提供优质教育时,健康干预才可能提高学生的学习水平。
