Purpose: To examine the longitudinal impact and mechanism of peer network status on university students’ hurdle running academic records. Methods: Conduct a follow-up survey in the hurdle teaching, an experimental class, and analyze the data using the latent growth model. Results: (a) The intercept and slope of peer network status positively predict the slope of academic records. (b) Peer network status influences the slope of academic records through the slope of learning engagement, and the intercept of learning engagement acts as a masking effect between the two. (c) Personality traits moderated the relationship between peer network status and the academic records slope. Conclusions: (a) The impact of peer network status on academic records exhibits social effects. (b) The impact of peer network status on academic records has a double-edged sword effect. (c) Extroverted personality is most advantageous in enhancing peer network status and predicting the rate of improvement in academic records.

目的：探讨同伴网络状态对大学生跑成绩的纵向影响及机制。方法：对跨栏教学、实验班进行跟踪调查，并利用潜在增长模型对数据进行分析。结果：（a）同伴网络状态的截距和斜率正向预测学业记录的斜率。 (b) 同伴网络状态通过学习参与度的斜率影响学业成绩的斜率，学习参与度的截距在两者之间起到掩蔽效应。 (c) 人格特质调节同伴网络状态与学业成绩斜率之间的关系。结论：（a）同伴网络状态对学业记录的影响表现出社会效应。 (b) 同伴网络状态对学业成绩的影响具有双刃剑效应。 (c) 外向性格最有利于提高同伴网络地位和预测学业成绩的改善率。
