摘要
社会网络分析(SNA)为学科研究提供了新手段和新方法,通过构建我国教育技术研究高频词共词网络并进行社会网络分析,可以从一个新的角度了解我国教育技术研究现状。研究结果揭示,我国教育技术高频词共词网络是一个密度较大、网络聚集度较好、具有小世界效应的网络,体现出我国教育技术研究比较成熟;"远程教育"等5个高频词的三种中心度均居前列,它们是我国教育技术的热门研究主题,具有最强的影响力,对共词网络的形成起着最主要的作用;共词网络存在5个最大的1-派系,"信息技术"等9个高频词是构成我国教育技术研究高频词共现网络各派系的骨干成员;共词网络存在核心——边缘结构,"信息技术"等7个高频词是我国教育技术研究的核心研究主题;共词网络可划分为12个学术领域,各自广度和成熟度都有较大差异。
This study employs a novel method, social network analysis(SNA) to analyze the co-word matrix of high fre-quency words in Chinese educational technology research, in order to understand its status quo from an alternative perspective. The results reveal that: 1) Chinese educational technology studies have fully grown, manifested by a matrix with high density and concentration, and an effect of small world; 2) Mostly researched topics include distance education and other four, whose concentration degree tops the rating, playing a major role in the matrix transformation; 3) There are 5 biggest 1-cliques in the co-word network, whose core members consist of information technology and other 8 high frequency words; 4) The co-word network features a core/ periphery structure, study themes centering on information technology and other 6 words; and, 5) The co-word network can be divided into 12 research fields, whose scopes and maturities are different from each other.
