In this increasingly regulated, but contested, climate, teacher education has become a field of study separate from the study of learning or teaching itself. The Oxford Encyclopedia of Global Perspectives on Teacher Education includes new articles on innovative, grounded, and theory-based work being done by established global scholars who are interrogating educational issues related to teacher education. A major aim of the project is to pave the way for scholars to learn from each other, recognizing not only similarities but also differences in perspectives, and in doing so, encourage those working in teacher education to create more sustainable, focused, and collaborative approaches to the merging of theory and practice. The Encyclopedia is international in scope and encompasses the breadth of significant scholarship in the field of teacher education from both well-known and emerging scholars. Comprehensive in nature, it includes new foundational essays on the most pressing issues impacting teacher education and includes analytic essays from across the globe. Topics include a balance of critical, historical, psychological, and sociological perspectives. Written with both early-career and more experienced scholars in mind, the collection provides international perspectives on crucial topics such as social justice and equity in teacher education, and features a number of scholars from Indigenous communities and the Global South. As teacher education is increasingly held responsible for everything from falling PISA rankings, widening achievement gaps, and lower student outcomes to even poverty itself, this volume is particularly timely in its collection of the most significant thinking and research in the field.
