同伴特征与初中学生成绩的多水平分析

Peer Characteristics and Student Achievement: A Multilevel Analysis

本文利用由”小升初”计算机随机派位产生的同伴特征的随机变化来分析同伴能力等对初中学业发展的影响。多水平分析结果表明，同伴能力对已数学标准化分数衡量的个人成绩有不显著的正向、非线性的影响。此外，研究发现学生成绩会因为同伴能力差异的扩大而显著地降低。

This study uses random variations in characteristics of classroom peers generated by random assignment of elementary school graduates to junior high schools to analyze the impact of peer characteristics on individual academic attainments. HLM analysis didn’t find significant positive peer effects in nonlinear manner， whereas wider variations of peer performance reduce math test score.
