This volume presents an innovative approach to understanding the language socialization process of second language learners in study abroad programs, focusing on the case of study abroad programs in Japan. Study abroad experiences are so diverse that both macro and micro viewpoints are needed to capture such complexity. This book looks for a way forward by adopting a novel approach which integrates social network analysis and conversation nalysis and allows for a fuller, more nuanced understanding of varying experiences of study abroad participants. Chapters draw on data from a wide range of sources, including participant observation, semi-structured interviews, social network surveys, and audio and visual recordings, to demonstrate the ways in which broader social forces, environmental factors, and individuals' dispositions interact in myriad social contexts within the study abroad experience. Taken together, the volume offers readers a comprehensive portrait of social processes in study abroad programs and their implications for language development, making this key reading for students and scholars in second language acquisition, pragmatics, and applied linguistics.
