Book excerpt: Computers play a crucial and rapidly evolving role in education, particularly in the area of language learning. Far from being a tool mimicking a textbook or teacher, Computer-Assisted Language Learning (CALL) has the power to transform language learning through the pioneering application of innovative research and practices. Technological innovation creates opportunities to revisit old ideas, conduct new research and challenge established beliefs, meaning that the field is constantly undergoing change. This fully revised second edition brings teachers and researchers up-to-date by offering: A comprehensive overview of CALL and current research issues Step-by-step instructions on conducting research projects in CALL Extensive resources in the form of contacts, websites and free software references A glossary of terms related to CALL Closely linked to other branches of study such as autonomy in language learning and computer science, CALL is at the cutting edge of current research directions. This book is essential reading for all teachers and researchers interested in using CALL to make language learning a richer, more productive and more enjoyable task.
