大学生兼职影响其学业成绩吗？——来自元分析的证据

There are competitive hypotheses and contradictory empirical results on whether college students' part-time jobs affect their academic performance. Based on 32 valid studies involving 57 effect sizes and 55,973 samples, using the meta-analysis method, this study attempts to explain the contradictory results. The results showed that, in general, there was a weak conflict effect between having part-time jobs and academic achievement (r=-0.083). However, part-time jobs that were related to college students’majors would improve their academic performance; Working less than 10 hours a week was also associated with higher grades, above which the longer the working hours were, the greater the decline in academic performance. In conclusion, universities should attract job-oriented students to re-engage in the study, and motivate students to choose high-quality part-time jobs closely related to their majors and appropriately allocate time spent in part-time jobs to weaken the negative impact of part-time jobs on acade
