This book takes as its starting point the assumption that interpersonal communication is a crucial aspect of successful language learning. Following an examination of different communicative models, the authors focus on traditional face-to-face (F2F) interactions, before going on to compare these with the forms of computer-mediated communication (CMC) enabled by recent developments in educational technology. They also address the question of individual differences, particularly learners' preferred participation styles, and explore how F2F and CMC formats might impact learners differently. This book will be of interest to students and scholars of computer-mediated communication (CMC), computer-assisted language learning (CALL), technology-enhanced language learning (TELL), language acquisition and language education more broadly.
