This book is a practical guide for English language teachers and teacher educators seeking to carry out and promote teacher action research within their institutional context. Based on contemporary theory and a reflexive and social approach to teacher professional development and learning, it offers readers structured methodologies and concepts, wide-ranging hands-on activity sets, and focused suggestions for appropriate and sustainable ways to implement action research across an institution. Experts Anne Burns, Emily Edwards and Neville John Ellis close the book by presenting ideas for conducting teacher research through reflective practice, exploratory practice and action research.
