| 1 | Heterogeneity Analysis on the Influence of the Supply of Teachers on the Academic Performance of 15-Year-Old Students:Based on PISA 2018 Samples from Four Provinces and Municipalities in China显示文摘The quantitative and qualitative supply of teachers has a significant influence on student academic performance.Based on the samples collected from four provinces and municipalities in China for the Program for International Student Assessment(PISA)2018,this study analyzes the effects of the supply of teachers on the academic performance of 15-year-old students through a hierarchical linear model(HLM)as well as a quantile regression model.The study has found that the shortage of teachers and the proportion of teachers with a master’s degree significantly affect student academic performance,and the supply of teachers with higher degrees has a decreasing marginal benefit on student academic performance;its best marginal benefit on student academic performance is achieved when the proportion of teachers with a master’s degree reaches about 75%.For students in different academic performance subgroups,the marginal benefit of an increase in the proportion of teachers with a master’s degree in schools is higher for“top students”than for“students with learning difficulties.”In terms of the difference between urban and rural areas,the shortage of teachers in rural schools is more prominent than that in urban schools,and teachers with higher degrees tend to cluster in core cities.The marginal benefit of an increase in the proportion of teachers with a master’s degree is higher for improving student academic performance in rural areas.Therefore,it is recommended to design a policy of differentiated compensatory earnings for rural teachers,and efforts should be enhanced to promote programs for supporting high-quality teachers.In addition,the allocation of teachers should follow the principle of“differentiated equity,”and more differentiated teaching strategies should be adopted for students with different academic abilities. | YE Fangru | 2022 | Frontiers of Education in China2022，17，2： | 0 |
