Preparing teachers to work with and for diversity in their classrooms and beyond is an objective that seems to be globally accepted in pre-service and in-service teacher education. However, what diversity means, what it entails and how to engage with diverse individuals in educational contexts can take on multiple shapes in different parts of the world. This Element suggests that the multifaceted and polysemic notion of interculturality could be useful to unthink and rethink (ad infinitum) working with diverse people in education. The Element surveys the different meanings and ideologies attached to the notion, using a multilingual perspective to do so. Recent research published internationally on the topic and its companions such as multicultural is also reviewed. The main addition to the field is a critical and reflexive perspective which is proposed for teacher educators, (students) teachers and researchers. The proposal draws from Dervin's most up-to-date theoretical and pedagogical work.
