Computer-assisted language learning (CALL) is an approach to teaching and learning languages that uses computers and other technologies to present, reinforce, and assess material to be learned, or to create environments where teachers and learners can interact with one another and the outside world. This book provides a much-needed overview of the diverse approaches to research and practice in CALL. It differs from previous works in that it not only surveys the field, but also makes connections to actual practice and demonstrates the potential advantages and limitations of the diverse options available. These options are based squarely on existing research in the field, enabling readers to make informed decisions regarding their own research in CALL. This essential text helps readers to understand and embrace the diversity in the field, and helps to guide them in both research and practice. Contents include: (1) Introduction (Glenn Stockwell); (2) Diversity in learner usage patterns (Robert Fischer); (3) Diversity in learning training (Philip Hubbard and Kenneth Romeo); (4) Diversity in learner support (Hayo Reinders and Pornapit Darasawang); (5) Diversity in environments (Glenn Stockwell and Nobue Tanaka-Ellis); (6) Diversity in content (E.
