The Effectiveness of Single‐Sex Schools through Out‐of‐School Activities: Evidence from South Korea
利用首尔随机分配学生入学的数据，研究发现单性别学校通过增加学生课外学习时间，解释了21%-30%的成绩提升效果，对教育政策制定者评估单性别学校价值有参考意义。
Abstract Students’ out‐of‐school activities and time use can play a crucial role in facilitating the effect of schools on students’ achievement. Using data from Seoul, South Korea, where students are randomly assigned into schools, we show that when single‐sex schools improve students’ test performance, their effect is positive on students’ time spent on study‐related out‐of‐school activities. Our results indicate that out‐of‐school activities explain roughly 21%–30% of the effect of single‐sex schooling on test performance.
