Leading theorist directly addresses the issues and criticisms that surround the development and implementation of TBLTTask-based language teaching (TBLT) is now a well-established approach to teaching foreign languages which draws on theories of second language acquisition and on general educational principles. However, there remain a number of issues that need to be considered in designing and implementing TBLT in classroom settings. This book, written by a leading theorist in the field, bridges this gap by addressing the key issues which are important for its development. These issues include the difference between task-based and task-supported language teaching, the role of input tasks, how tasks engage learners, task complexity, catering for individual differences in learners and teacher-preparation for TBLT. Overall, the book provides a comprehensive account of TBLT and makes a significant contribution to the growing literature in the field.
