我国外语教学中的自主学习研究综述——以社会网络分析为视角

Research Summary for Language Autonomous Learning in China from the Perspective of SNA

文章从外语教学中的自主学习（autonomous learning）研究文献中提取关键词，经过数据处理后形成共词（co-words）网络。通过共词网络社群图（sociogram）的绘制、密度（density）分析、中心性（centrality）分析、核心-边缘（core/periphery）分析等常用社会网络分析（social network analysis，简称SNA）技术，揭示我国外语教学中自主学习的研究现状与未来发展趋势。

Quantitative process of social network analysis (SNA) was introduced to construct a co-words network of autonomous learning research documents from 1978 to 2010 in China. Sociogram construction， density measurement， centrality and core-periphery analysis were employed to reveal the research status and the trend of autonomous learning.
