摘　　要：协作学习在教育中广泛应用并备受关注。最近几年的研究重心已经转移到如何分析协作学习的交互过程。研究者也为此提出了不同的方法来分析复杂的交互现象。从复杂系统的视角提出了基于信息流的协作学习交互分析方法,并采用该方法分析协作学习系统中信息流的时间和空间特征。研究中采用准实验法搜集了121个样本的数据。结果发现,聚焦点随着时间呈现回溯和转移的特征,知识点随着时间的激活序列具有非线性的特征。不同交互效果协作组的信息流映射而成的知识图之间具有明显的差异性,但就信息类型和表征方式方面,不同交互效果的小组却没有显著性差异。Collaborative learning has attracted more and more scholars＇ attention in recent years,whose research focus is transferred to analyze the interactive process in collaborative learning.Researchers have put forward various kinds of methods to analyze the complicated interactive phenomenon.An interaction analysis method in collaborative learning based on information flows from the perspective of complex system is proposed in the paper,with which the temporal and spatial characteristics of information flows are analyzed based on 121 samples.The results are as follows：（1） the focuses have the characteristics of backtrace and transfer over the time;（2） knowledge has the nonlinear characteristics with the time ＇s activation;（3） there are significant differences in knowledge map between different performance groups.However,there are no differences in information types and representations between different performance groups.
