二语习得知识领域2009-2019年间的可视化研究

A Decade of Research Into Second Language Acquisition:A State-of-the-Science Review(2009-2019)

本文以2009-2019年二语言习得(SLA)知识领域为研究对象,由于二语习得知识领域的快速发展和多元化研究,本文选择近10年的二语习得研究文献和采用一种新兴的数据分析工具CiteSpace对二语习得知识领域进行文献综述,利用Web of Science数据库主题检索了2009-2019年二语习得相关的4660条文献。研究发现二语习得的影响因素和统计模型是研究的重要方面,且研究主题集中在心理学、神经科学、语言学和语言教学等框架。此外,二语习得研究内容也日趋多样化,近年来认知科学的实证研究逐渐占据主导地位。同时本文对二语习得知识领域的可视化研究显示在未来一定时间内跨学科研究可能会吸引更多学者的眼球。

This study investigated the knowledge domain of second language acquisition(SLA)research in 2009-2019.It selected about a decade of studies in the SLA knowledge domain and applied an available data analysis tool CiteSpace to show a picture of SLA research.The 11-year period of studies was retrieved from the Web of Science database,totally 4,660 bibliographic records.By employing the embedded algorithm analyzing literature in CiteSpace,the present study found the factors influencing SLA and statistical models were critical aspects in L2 research,and research topics were conducted in psychological,neuroscience,linguistic,and language teaching frameworks.Additionally,research patterns in the SLA domain have become more diversified,and empirical studies of cognitive science have gradually taken a dominant position in recent years.Spikes of increased numbers of detected papers in the period of 2009-2019 showed research focus and methodology would possibly continue to be interdisciplinary in future research.
