This exciting companion volume explores how intercultural perspectives can inform and transform teacher education and professional development. The book addresses the practical challenges and opportunities that educators face when responding to diversity in all its forms within learning environments. Engaging with the flexible notion of interculturality, it encourages critical and transparent discussion of its many interpretations. A core principle is that teacher education is never isolated, but is always situated within specific local and global contexts, influenced by factors such as identity, ideology and policy. This Companion serves as a key reference, guiding readers to contextualise, conceptualise and critically evaluate the role of interculturality in teacher preparation. Covering topics ranging from languaging and decolonising methodologies to digital technologies and artificial intelligence, this book is an indispensable resource for researchers, students and practitioners involved in pre-service training, in-service professional development and self-directed professional learning.
