摘要本研究旨在探讨课外辅导与私教对韩国中学生学业成绩之因果关系。本研究使用京畿道教育小组研究的学生数据进行实际数据分析。该研究试图通过使用倾向得分的逆概率权重来调整对asp或私人辅导的可能选择偏差，该倾向得分来自一个看似无关的双变量概率模型。结果表明，即使在控制了对两种治疗方法的选择偏差之后，asp和私人辅导都对韩国中学生学业成绩的提高做出了贡献。研究发现，不同教育水平的学生参加asp或家教的影响程度不同；在初中生中，私人辅导对学业成绩的影响大于asp，而asp对高中生学业成绩的影响大于私人辅导。此外，我们还发现，在初中，ASP参与与私人辅导参与之间不存在交互效应，但在高中存在负交互效应。此外，为了更深入地检验asp和家教对中学生学业成绩的影响，我们计算了区域大小的差异效应，结果表明asp和家教对中学生学业成绩的积极影响仅在城市地区显著。
The purpose of this study is to examine the causal effects of after-school programs (ASPs) and private tutoring on Korean secondary school students' academic achievement. The students' data from the Gyeonggi Education Panel Study were used in this study for the actual data analysis. The study attempted to adjust for possible selection bias toward either the ASPs or private tutoring by using the inverse probability weight of the propensity score, which was derived from a seemingly unrelated bivariate probit model. The results demonstrated that ASPs and private tutoring both contributed to increases in Korean secondary school students' academic achievement, even after controlling for the selection biases toward both treatments. The magnitude of the effects of participating in ASPs or private tutoring was found to differ by education level; in middle schools, private tutoring showed a higher impact on academic achievement than did ASPs, whereas ASPs had a greater influence on high schools students' academic achievement than did private tutoring. Moreover, it was also revealed that there was no interaction effect between ASP participation and private tutoring participation in middle schools, but that a negative interaction effect existed in high schools. In addition, the differential effect of region size was calculated in order to examine the effect of ASPs and private tutoring in more depth, and the results demonstrated that the positive effects of ASPs and private tutoring on secondary school students' academic achievement were only significant in urban areas.
