Teachers often find that materials get between learners and learning for a variety of reasons. Because learning materials play a significant part in lessons, it is important they fit for purpose. Mann and Copland have elicited and included comments and suggestions from several teachers, teacher educators, and coursebook experts to illustrate their discussions and to bring the practitioner voice into play. They provide principles and approaches for adapting material to suit a variety of contexts and show how teachers can work successfully with limited resources. The authors are also concerned with the choices teachers and learners have with regard to the timing and location of learning, and include a discussion of homework, virtual learning environments, and the flipped classroom.
