Chapter 16: Language Socialization, Discourse, and Second Language Research (Duff & Yamamoto, 2024)

Abstract
Language socialization research examines the concurrent development of linguistic and cultural knowledge through mediated social experience including, in some cases, explicit instruction. Increasingly, language socialization research is conducted in multilingual contexts, both inside and outside of classrooms, where second- or additional-language (second language) development is one of the expected outcomes of interaction. Other goals often include the transmission and uptake of linguistic ideologies and social values, membership in a particular real or desired community mediated by the second language, and forms of content knowledge that are learned and expressed at least in part through an additional language. This chapter first presents the theoretical underpinnings of language socialization and the main research methods or approaches used in language socialization studies. Then, second language socialization processes are illustrated through selected sample studies and examine how LS research has analyzed oral, written, and multimodal discourse. The focus is on research situated within classrooms and other, less formal, settings (e.g., dormitories), where multilingual students engage in discursive events and interactions with teachers and peers through their second language, with the goal of developing their second language proficiency and other competencies. How such interactions and discourse contribute to participants’ second language or multilingual development are then discussed and how their understandings of local cultural ideologies are connected with the second language. The chapter concludes with a discussion of implications for educators and promising directions for future research.
