Whether teachers maintain their expectation bias for students over time is crucial for understanding self-fulfilling prophecy effects. However, the stability of teacher expectation bias has been largely ignored in the literature. We examined the stability of teacher expectation bias across a sample of teachers and the change trajectories of teacher expectation bias across high-, medium-, and low-expectation teacher groups across all teachers and in the curriculum areas of mathematics, Chinese, and English. Our analyses were based on two-year longitudinal data with four time points from 567 Chinese senior high school students and their 50 teachers. The results showed that across all teachers, teacher expectation bias at the individual student level was dynamic over time. That is, teachers seemed to adjust their initial expectation bias in the first few months but then maintained the adjusted expectation bias afterwards. However, when students moved from Grade 11 to Grade 12 (the last year of high school), teachers seemed to change their expectation bias again. The evidence from HLM analyses further supported these results. That is, all the high- and low-expectation teachers alleviated their initial expectation bias significantly in the first six months and then adhered to their adjusted expectation bias. However, when students moved to the last year of high school, some high- and low-expectation teachers’ expectation biases were volatile again. Nevertheless, most high- and low-expectation teachers (except for Chinese low-expectation teachers) tended to either over-estimate or under-estimate their students across two school years. Further, compared to Chinese and mathematics teachers, English teachers’ biases seemed to be even more stable. Our findings suggested that some teachers consistently over- or under-estimated their students over an extended time period and this could have implications for student outcomes.
相似文献Parent–adolescent relationships play an important role in protecting adolescents from depressive symptoms. However, there are no consistent conclusions about the extent to which fathers and mothers uniquely contribute to adolescents’ depressive symptoms. The present study aimed to acquire knowledge in this research area in two ways. First, this study separated the potential impacts of father–child and mother–child relationships on depressive symptoms in Chinese adolescents. Second, this study used a longitudinal design with nationally representative samples from the China Education Panel Survey. A total of 8794 middle school students in grade 7 completed measures of father–adolescent and mother–adolescent relationships, and depressive symptoms twice (T1 and T2; one-year interval). Results indicated that both positive father–adolescent and mother–adolescent relationships had negative effects on depressive symptoms in female adolescents. However, positive father-adolescent, not mother-adolescent, relationships had a negative effect on depressive symptoms in male adolescents. These findings suggest that positive parent–adolescent relationships could reduce early adolescents’ depressive symptoms, but positive father–adolescent and mother–adolescent relationships might have different protective effects on early adolescents’ depressive symptoms among male and female adolescents in China.
