Teachers Investigate Their Work introduces the methods and concepts of action research through examples drawn from studies carried out by teachers. The book is arranged as a handbook with numerous sub-headings for easy reference andnbsp;fourty-one practical methods and strategies to put into action, some of them flagged as suitable `starters'. Throughout the book, the authors draw on their international practical experience of action research, working in close collaboration with teachers. Itnbsp;is an essential guide for teachers, senior staff and co-ordinators of teacher professional development who are interested in investigating their own practice in order to improve it.
