Teacher identity refers to the self-perception, beliefs, values, and sense of professional self that teachers hold. It encompasses how teachers view themselves as professionals, their roles and responsibilities in the classroom, and their interactions with students, colleagues, and parents. Research on teacher identity explores the factors that influence how teachers construct and develop their identities, the impact of their identities on teaching practices and student outcomes, and strategies for supporting and enhancing teacher identity development. This area of research is important for understanding how teachers can be better supported in their professional growth and development.
