国内二语词汇附带习得研究综述(2003-2019)——基于CiteSpace可视化分析

Review of Incidental Vocabulary Acquisition in Second Language(2003-2019):Visualization Analysis Based on CiteSpace

词汇附带习得在二语习得领域一直备受关注。以CiteSpace可视化工具为主,以CNKI (中国知网)计量分析工具为辅,对国内词汇附带习得的期刊文献(2003-2019)的年度发表趋势、研究者分布、关键词词频、关键词突发性和关键词演进逐一进行可视化分析,旨在梳理国内词汇附带习得的研究热点与研究趋势。研究发现:当前二语词汇附带习得研究集中在投入量、阅读和注释3方面,重在考察投入量、阅读任务和注释3个因素对词汇附带习得的效果;研究立足于词汇教学和阅读教学,凸显的关键词是"投入量(Involvement load)"和"词汇量(Vocabulary)",显示这是二语词汇附带习得的两大研究热点;近几年来,词汇附带习得研究开始从阅读领域转向听力领域,从外部影响因素研究转向学习者内部影响因素研究,学习者个体差异研究开始升温。
