Introduction From an early limited conceptualization as the application of linguistic knowledge to language teaching (Cook, 2015), current Applied Linguistics (AL) is a vibrant interdisciplinary field that considers within its domain any social problem in which language is implicated (Brumfit 1995, cited in Myers, 2005). Given that it is difficult to imagine a sphere of social life in which language is not implicated (Myers, 2005), demarcating the borders of AL research is difficult to articulate (Chapelle, 2013; Cook, 2015; Kaplan, 2010). This continuous diversification in scope requires that “researchers ask and address different research problems, employing a variety of philosophies and methodologies.” (Phakiti, et al. 2018, p. 6). The expansion in both the substantive domain and in the array of data sources and analytical tools that are used in AL research demands that the repertoire of research methods in AL undergo continual updates and critique. The handbook edited by Phakiti et al. is a major step in this direction.

引言从将语言知识应用于语言教学的早期有限概念化（Cook，2015）以来，当前的应用语言学（AL）是一个充满活力的跨学科领域，在其领域内考虑了与语言有关的任何社会问题（Brumfit 1995，引用在Myers，2005年）。鉴于很难想象没有语言牵连的社会生活领域（Myers，2005年），很难阐明AL研究的边界（Chapelle，2013年； Cook，2015年； Kaplan，2010年）。这种范围的不断多样化要求“研究人员采用各种哲学和方法来提出和解决不同的研究问题”。（Phakiti等人，2018，第6页）。在AL研究中使用的实质性领域以及数据源和分析工具的扩展都要求AL研究方法的总目录不断更新和批判。该手册由Phakiti等编辑。是朝这个方向迈出的重要一步。
