Focusing on what can be done to promote equity within education systems, what the barriers to progress are and how these barriers might be overcome, this book provides detailed examples of strategies that have proved to be effective in addressing this challenge. Built on the work of the authors over the last three decades, the book presents an approach to educational change that will be relevant to different countries.The authors argue that there is untapped potential for promoting progress towards greater equity within schools and the communities they serve. They also show how this potential can be mobilised by using forms of collaborative action research to stimulate the development of more inclusive ways of working. Central to this approach is the use of evidence collected by practitioners with the support of university researchers, drawing on the human resources that are there in every school.Grounded in research, evidence and experience in the field, this book is ideal reading for a wide audience of practitioners and policy makers globally, including senior staff in schools, as well as post-graduate students, researchers and academics who are focusing on educational improvement.
