运用社会网络分析法,以优秀教师L老师的博客为例,研究成员之间的互动情况,同时辅以内容分析法对回复内容进行对比分析。从中心度、密度、凝聚子群数据和内容分析的结果显示,L老师的博客非常缺乏深度的互动,更缺少对实践问题的集思探讨,同样存在着“李克东难题”现象。 Using the social network analysis method, taking the blog of excellent teacher L teacher as an example, this paper studies the interaction among members and at the same time supplements the content analysis method to compare the reply contents. From the results of centrality, density, cohesive subgroup data and content analysis, it shows that there is a lack of deep interaction between L teachers’ bloggers and the lack of discussion on practical problems. There is also the phenomenon of “Li Ke Dong Puzzle”.
