Secondary research in the form of literature reviews facilitates consolidation and transfer of knowledge. In the field of TESOL, the majority of secondary research is conducted in the form of narrative reviews, which rely on the researchers' selection and interpretation of primary studies and findings. Systematic reviews, which can be broadly categorized into meta-analysis (focusing on quantitative data) and qualitative research synthesis (focusing on qualitative data), are gaining popularity (see Plonsky, 2017) but are still less common. In particular, qualitative data collected from language classrooms, which are often criticized because of their lack of generalizability, are seldom synthesized in a systematic fashion. Against this backdrop, this article first attempts to make a case for conducting qualitative research synthesis in the field of TESOL. Second, this article provides a methodological framework and an example of how qualitative research synthesis can be conducted. The article closes with recommendations to promote qualitative research synthesis in the field of TESOL.

TESOL 中的定性研究综合入门

以文献综述形式进行的二次研究有助于巩固和转移知识。在 TESOL 领域，大多数二级研究以叙述性评论的形式进行，这依赖于研究人员对初级研究和发现的选择和解释。系统评价可以大致分为元分析（侧重于定量数据）和定性研究综合（侧重于定性数据），越来越受欢迎（参见 Plonsky，2017），但仍然不太常见。特别是从语言课堂收集的定性数据，由于缺乏普遍性而经常受到批评，很少以系统的方式综合。在这样的背景下，本文首先尝试为在TESOL领域进行定性研究综合做一个案例。其次，本文提供了一个方法框架和一个如何进行定性研究综合的例子。文章最后提出了促进 TESOL 领域定性研究综合的建议。
