Evidence on whether afterschool programs enhance academic achievement is limited and mixed. In this study, a group of community providers delivered interventions to students to improve academic achievement. We used propensity score matching to estimate the impact of these afterschool interventions on third-grade reading achievement. A significant effect of moderate magnitude was found favoring students who participated in afterschool programming. Propensity score matching and other methodological considerations are described to support the importance and value of conducting rigorous evaluations of afterschool programs.
关于课外项目是否能提高学习成绩的证据有限且混杂。在这项研究中，一组社区提供者向学生提供干预措施，以提高学习成绩。我们使用倾向评分匹配来估计这些课外干预对三年级阅读成绩的影响。结果发现，课外项目的参与对学生有显著的中等程度的有利影响。描述了倾向评分匹配和其他方法学考虑因素，以支持对课外项目进行严格评估的重要性和价值。
