小学生能从课后学习时间中受益吗

Can Pupils of Primary Schools Benefit from the Study Time after Class

基于2016年中国区域基础教育质量健康体检与改进提升项目大规模调查与测评数据,研究采用描述统计和工具变量回归模型,对小学生课后学习时间分布状况,及其对学业成绩的影响效应展开分析。研究发现:1.整体而言,小学生的校内外学业负担较重,而且校内作业负担要重于校外作业负担,校外补习时间要长于校内补习时间;2.作业时间对小学生的学业成绩有显著的负影响,学生作业时间越长,学业成绩越低;3.校内补习时间对小学生学业成绩有显著的负影响,校外补习时间对小学生学业成绩有显著的正影响。因此,无论是学校还是家长,不应给学生安排过多的课后学习时间,适量的课后学习时间才能最大限度地促进学生学业成绩的提升。

The paper uses the data of evaluation of basic education from the National Collaboration and Innovation Center,andemploys the descriptive statistical analysis and IV estimation approach to analyze the relationship between the study time after class and pupils achievements.We find that:firstly,primary school pupils have a heavy study load,and the burden of internal homework is heavier than that of external homework.The external extracurricular tutoring on primary school pupils is longer than that of internal extracurricular tutoring.Secondly,the homework has a significant negative effect on pupil achievements.The longer the pupils work,the lower the pupil achievements.Thirdly,the internal extracurricular tutoring has a significant negative impact on the academic performance of pupils,and the external extracurricular tutoring has a significant positive effect on pupil achievements.Therefore,neither schools nor parents should assign too much study time after class.Suitable time is the best to improve pupils achievements.
