Campbell Syst Rev. 2021 Oct 26;17(4):e1199. doi: 10.1002/cl2.1199. eCollection 2021 Dec.

Abstract

This review will synthesize the results from publications focused on homework time and academic performance, and estimate the relationship between the two. Our objectives are: (1) To identify the extent of the relationship between homework time and students' academic performance; (2) To analyze the differences in the effectiveness of homework time across genders, grades, subject and regions; and (3) To identify the potential factors that affect homework time, such as academic subject, task difficulty, type of homework, mode of homework, parental involvement, and feedback on homework.
