Making a Difference in Theory brings together original work from an international group of authors on the roles of theory in educational research and practice. The book discusses the different roles theory plays, can play and should play, both from a historical perspective and in light of contemporary discussions and developments. Particular attention is paid to the question of whether there are or should be distinctively educational forms of theory and theorising. The double engagement with the theory question in education and the education question in theory and theorising provides original insights in what theory does, might do or should do in educational research and practice. With contributions from internationally renowned authors in the field of educational theory, research and practice, the book will be of value to academics, researchers and postgraduate students in education.
