This volume consists of fifteen articles on current issues in developing materials for language teaching. The main objectives are to help readers to apply current theoretical principles and research findings to the practical realities of developing and/or exploiting classroom materials and to offer new ideas and directions in materials design that readers can pursue for themselves. The chapters are grouped into the following five themes: - Research and materials development; - Data collection and materials development; - Methodology and materials development; - Teachers and materials development; - Evaluation of materials. The contributors are all well known in the fields of applied linguistics and language teaching for their publications on language teaching methodology and many have additionally published language teaching materials for students and teachers.
