This book examines the role of computers in language learning and teaching in higher education. In particular it considers the pedagogical and practical value of designing a languagelearning environment around computer technology. Whereas considerable research has already been undertaken in analysing the value of individual computer tools and packages such as email the study gives a broad appraisal of their individual and collective value without being too exhaustive. Using quantitative and qualitative data based on research visits to three universities Ulster Cambridge and Toronto this study provides examples of effective practice in the area of the exploitation of Information and Communication Technology for language learning and teaching. It draws on the experience of these three institutions as well as the findings of current literature in this area in order to establish a set of essential criteria that institutions need to meet when creating a computerbased environment. Although these criteria are based on experience with languagelearning environments they are essentially generic in nature and may be applied to other computerbased learning environments.
