This edited volume examines research and practical examples of professional learning approaches for school leaders and teachers in the areas of diversity, equity and democracy – ‘big issues’ that represent some of the most urgent challenges facing our societies and schools today. Educators from Ireland, Poland, Spain, Norway and Chile provide unique insights into professional learning programmes that were intentionally and collaboratively designed and put into action with and for school leaders, teachers and teacher educators. A key principle promoted throughout this book is the commitment to placing individuals, communities and context at the centre. All programmes emphasise the creation of new spaces, where lived experiences, evolving ideas and theoretical frameworks can be explored with honesty, critical depth and moral purpose. They prioritise transformative practice and outcomes through learning together, rather than through mere implementation or replication of programmes or policies. In offering summaries and critical discussions of key theoretical perspectives, learning materials and thinking points, and ultimately a shared sense of solidarity in the ongoing work of shaping transformative educational change, this book will be useful for school leaders, teachers, teacher educators, teacher professional development providers and policymakers working in the areas of diversity, equity and democracy.
