“人以群分”适用于大学生的学业成就吗——基于社会网络分析和Meta分析的方法

嵌入班级网络中的大学生在交往中形成不同的小群体,这些小群体间的学业成就是否具有显著性差异?研究者将社会网络分析方法中的整体网分析与元分析(Meta分析)相结合,在对大学生班级内小群体的学业成就差异进行多项独立研究的基础上,运用元分析技术将29项研究(N=1076)的结果予以综合分析,得到如下结论:(1)每个班级的大学生都在互动过程中形成了不同数量的小群体,且每个小群体中的学生数量不同;(2)大学生学业成就存在着“人以群分”现象,即同一班级的大学生在互动中产生的小群体在学业成就上存在显著性差异。因此,大学生应加强与高学业成就水平的小群体之间的互动以提高学业成就;而高校管理者也应采用科学的方法识别班级中的不同小群体,从而采取相应的学业成就提升策略。

Does “Birds of a feather flock together” Apply to the Academic Achievement of University Students?:A Study Based on Social Network Analysis and Meta-analysis

The social relations among university students who are embedded into the class network consists of multiple small groups in communication.This paper aims to explore whether there is a significant difference in academic achievement among these small groups.Combining the Whole Network Analysis with Meta-analysis in the methodology of social network analysis,researchers undertook several independent studies on the differences of academic achievement among those‘small circles’in the classes of university students.The results of 29 studies(N=1076)are comprehensively analyzed by using Meta-analysis technology,showing that(1)each class of students in the process of interaction formed different small groups with different number of students;(2)the phenomenon that“Birds of a feather flock together”does exist among university students,especially being represented as a significant difference of academic achievement in small group of students.Based on findings,the research suggests that students should try to establish good relations with their classmates who belongs to the small groups with high-levelled academic achievement;and university administrators should apply different strategies to improve academic achievement for different small groups of students.
