Quality and Equity in Education draws attention to the importance of developing and testing theories of educational effectiveness and using these theories for improvement purposes. It makes a major contribution to knowledge and theory building in research on promoting quality and equity in education. The book presents an improved version of the dynamic model of educational effectiveness based on the empirical data emerged from studies testing its validity, claiming that the proposed theory can be used for establishing links between educational effectiveness research and school improvement. Towards that end, the book presents the Dynamic Approach to teacher and school improvement, demonstrating its impact on quality and equity in education. The book not only proposes an agenda for further research on developing and testing the dynamic theory of educational effectiveness but also refers to research methods that can be used to test the assumptions of this theory and search for relevant cause and effect relations. The agenda also refers to the need of identifying the conditions under which the dynamic approach to teacher and school improvement can have an effect on student learning outcomes. This book will be of great interest for academics, researchers and postgraduate students working in education research and the area of quality and equity in education. It will also be of interest to policymakers, school advisors and other stakeholders in education.
