<div>This book was written for language teachers by language teachers, with a view to encouraging readers to use more tasks in their lessons, and to explore for themselves various aspects of task-based teaching and learning. It gives insights into ways in which tasks can be designed, adapted and implemented in a range of teaching contexts and illustrates ways in which tasks and task-based learning can be investigated as a research activity. Practicing language teachers and student professionals in graduate TESOL and Applied Linguistics programs will find this a rich resource of varied experience in the classroom and a stimulus to their own qualitative studies.<br></div>
