自应用语言学领域成立以来，案例研究一直在应用语言学中发挥着非常重要的作用，特别是在语言教学、学习和使用的研究中。此类研究中的案例通常是一个人（例如，教师、学习者、演讲者、作家或对话者）或少数个人单独或在一个群体中（例如，一个家庭、一个班级、一个工作团队或一个实践社区）。这些案例通常被深入研究，以提供对个人经历、问题、见解、发展途径或在特定语言、社会或教育背景下的表现的理解。不像一些定量研究那样，从更大的样本或对语言学习者群体的调查中得出统计模式或趋势来讨论结构、假设和发现，一个人的定性案例研究呈现了一个情境化的人的形象。案例研究通过分析与儿童、青少年、年轻人和老年人相关的语言、文化和社会现象，对理论的发展做出了重大贡献，产生了新的视角，或对应用语言学的早期理论进行了反驳或改进。近年来，应用语言学案例研究的范围已经扩大到包括许多以前未被充分代表的主题、语言情境、理论视角和人口。本文概述了一些传统的覆盖领域，然后在方法论、主题领域和与跨国、多语言和散居背景下的语言学习者有关的发现方面提供了新的焦点。
Case study research has played a very important role in applied linguistics since the field was established, particularly in studies of language teaching, learning, and use. The case in such studies generally has been a person (e.g., a teacher, learner, speaker, writer, or interlocutor) or a small number of individuals on their own or in a group (e.g., a family, a class, a work team, or a community of practice). The cases are normally studied in depth in order to provide an understanding of individuals' experiences, issues, insights, developmental pathways, or performance within a particular linguistic, social, or educational context. Rather than discuss constructs, hypotheses, and findings in terms of statistical patterns or trends derived from a larger sample or survey of a population of language learners, as in some quantitative research, a qualitative case study of a person presents a contextualized human profile. Case study has contributed substantially to theory development, generating new perspectives or offering a refutation or refinement of earlier theories in applied linguistics by analyzing linguistic, cultural, and social phenomena associated with children, adolescents, young adults, and older adults.In recent years, the purview of case studies in applied linguistics has expanded to include many previously underrepresented topics, linguistic situations, theoretical perspectives, and populations. This article provides an overview of some traditional areas of coverage and then newer foci in terms of methodology, thematic areas, and findings pertaining to language learners in transnational, multilingual, and diaspora contexts especially.
