基于CiteSpace对国际词汇附带习得的可视化分析

词汇附带习得作为词汇习得主要方式之一,于二十世纪六十年代开始受到学者广泛关注。文章以Web of Science数据库国际权威期刊中关于词汇附带习得的学术论文以及会议论文为数据来源,利用CiteSpace的信息可视化技术,绘制词汇附带习得领域的知识图谱,分析该领域的发展趋势,研究热点以及前沿动态。研究发现,目前词汇附带习得正处于发展的高潮,虽出现了高产作者,但高被引文献的被引频次不高,说明该领域的中心性不强;词汇附带习得已广泛应用于英语教学,“学生”一直是该领域的研究热点;随着科技的发展,“电视”对词汇附带习得效果的影响也日益受到人们的关注。
