This book provides an accessible introduction to some of the methods and theoretical approaches for investigating foreign language (FL) interaction and exchange in online environments. Research approaches which can be applied to Computer-Mediated Communication (CMC) are outlined, followed by discussion of the way in which tools and techniques for data-collection in diverse online contexts can contribute to our understanding of online foreign language interaction. The compilation of chapters presents a comprehensive overview of key issues in virtual, intercultural and multimodal research contexts and gives insight into the particular challenges and situations which this area of language learning implies. Researching Online Foreign Language Interaction and Exchange addresses the needs of researchers and newcomers to the area who are hoping to learn about the current state of the field by providing overviews of varying approaches and extensive literature review as well as extracts of real data to illustrate the theories, methods or issues in question.
