摘　　要：在线协作问题解决是一种基于协同知识构建的学习方式,了解协作中的群体认知特性对于提升协作问题解决效果具有重要意义。为探究在线协作问题解决不同阶段基于脑电一致性的群体认知特性,文章从认知神经科学的角度,通过在一堂大学计算机网络实验课中开展小组协作实验,分析了在线协作问题解决中的群体认知特性、不同协作阶段的群体认知特性差异、不同成绩学生认知同步的差异,结果表明:在问题理解阶段和问题解决阶段都存在群体认知同步,问题理解阶段的群体认知同步水平比问题解决阶段更高,不同成绩学生的认知同步存在明显差异。文章的研究提供了一种从脑电一致性角度评价在线协作问题解决交互有效性的手段,也为教师通过脑电数据实时监控学生的协作学习状态并及时干预提供了一种可选的方法。Online collaborative problem solving(CPS)is a learning method based on collaborative knowledge construction.It is of great significance to understand the group cognitive characteristics in collaboration to improve the effectiveness of CPS.In order to explore the group cognitive characteristics based on electroencephalogram(EEG)consistency at different stages of online CPS,this paper analyzed the group cognitive characteristics of online CPS,the differences of group cognitive characteristics at different stages of collaboration,and the differences of cognitive synchronization among students with different grades through group collaboration experiments conducted in a college computer network experiment course from the perspective of cognitive neuroscience.The results showed that group cognitive synchronization existed in both problem understanding stage and problem solving stage,and the level of group cognitive synchronization in problem understanding stage was higher than that in problem solving stage.And there was an obvious difference in cognitive synchronization among students with different grades.The research of this paper provided a means to evaluate the interactive effectiveness of online CPS from the perspective of EEG consistency,and also offered an alternative method for teachers to monitor students’collaborative state in real time and timely intervene through EEG data.
