The introduction of digital technology to video use has opened up new opportunities for raising the quality of teaching and learning. This book provides the first integrated account of how digital video can be used to develop teaching competence. It shows not only how using video can help teachers move towards more dialogic forms of teaching and learning, but also how such change benefits pupils’ learning and behaviour. Based on extensive literature reviews this book provides an overview of "visual teacher learning" and summarises what is known about instructional improvements that teachers can achieve by engaging in it. These reviews and the author’s empirical studies explain the activities, processes and organisational conditions needed for implementing visual teacher learning in teacher education and professional development. The book concludes with practical resources for practitioners incorporating the lessons drawn from theory and research.
