Book excerpt: This book shows how English language instructors in Japan explored the questions and issues which most closely affected them and their students in the language learning process. Each of the teacher-researchers had a puzzle. After reviewing existing literature, each writer found a way to adjust their practice, and in these chapters, they report on the results. Topics include educational technology, learner autonomy, feedback, and novel approaches to listening, reading and writing instruction. Although the contributors are working in Japan, classroom practitioners from the wider international language teaching community can benefit from the practical teaching approaches and accessible descriptions of practitioner research to be found in this book. A secondary audience of educational managers and teacher trainers will also find value in chapters which outline the ways in which an environment conducive to practitioner research can be facilitated.
