YouTube now has more searches than Google, indicating that video is a motivating and, potentially, powerful learning tool. This paper investigates how we can embrace video to support improvements in teacher education. It will draw on innovative approaches to teacher education, developed by the Open University UK, in order to explore in more depth the potential of video. It will use case studies from three continents, and draw on research from different sources, in order to highlight the successes and the challenges. Looking across the examples presented, the paper will describe models of teacher learning and video use, and demonstrate that video can add value to teacher development activities provided that appropriate support and mediation, consistent with the pedagogy that is being promoted, is in place. Sustainable Development Goal 4 emphasizes the importance of improving the quality of the experiences that children have in school. This requires new models for teacher education, and has become an urgent issue. Video could be a significant part of the solution.
