国外网络学习共同体研究的文献计量分析

A Bibliometric Analysis of Studies on Overseas E-learning Community

为了解国外网络学习共同体研究的发展路线、研究热点及趋势,以WOS为数据源,借助CiteSpace信息可视化计量工具,对国外近20年来(2000-2022)网络学习共同体相关主要研究进行文献计量分析。通过绘制关键词共现图谱,发现electronic learning,distance education,learning community,virtual community,knowledge management等出现时间较早,在新冠疫情之后,线上教学成为研究热点。从中介中心性指标来看,electronic learning、higher education和blended learning是研究焦点。利用突变检测计算得出阶段性研究热点,对其中关联度高的热点进行了研究分析。

Based on the papers retrieved from WOS between 2000 and 2022,this paper,with CiteSpace,makes a bibliometric analysis of the main studies on e-learning community in foreign countries,aiming to understand the phases,hotspots and trends of studies on overseas e-learning communities.By drawing co-word clusters of keywords,this paper finds that electronic learning,distance education,learning community,virtual community and knowledge management appeared earlier,and that after the COVID-19 epidemic,online teaching has become a research hotspot.From the perspective of betweenness centrality,main focuses are electronic learning,higher education and blended learning.Mutation detection is used to find periodic research hotspots,after which the high-correlation hot spots are analyzed.
