A norm-critical approach to teaching and learning, that is, an approach that challenges and changes taken-for-granted exclusionary norms and structures, enables teachers and students to recognize and deconstruct norms causing marginalization and exclusion. A norm-critical approach challenges the processes of othering. Teacher education and in-service training need to incorporate teaching materials and tools that enable teachers, students, and school administrators to act as change agents. All teacher educators and school personnel thus need to acknowledge their own role in upholding and dismantling unequal norms and practices. Particularly unequal norms and practices concerning aspects of diversity such as social class, gender, special needs, language, and ethnicity need to be changed.
