ABSTRACT
This chapter first traces the development of conversation analysis (CA) and membership categorization analysis (MCA) as branches of ethnomethodology, then describes their foundational principles and analytical procedures, with reference to specific tools and resources. After an overview of key topics in CA and MCA, including a brief discussion of criticisms, the chapter reviews CA-based and MCA-based studies in sociolinguistic research in second language acquisition (SLA), covering issues such as language policy and language ideologies, language choice and identity performances, the co-construction of native/non-native speaker identities, interactional competence, and sociolinguistic competence development. The chapter concludes with suggestions for future research directions.
