In the field of teachers' professional learning, 'Making a Difference' asks what could make a difference to practice and to knowledge about that practice? In addressing this question, the book sets an agenda for future research and practice within the field of teachers' professional learning. It aims to examine what we know now, what is currently occurring in practice and what reasons might lie behind the fact that practice and policy seem to be 'stuck'. Within the field of research and practice, the authors look at what seems to make a difference and how this can be developed.
