I approach teacher action research from an interpretive phenomenological perspective to understand the meaning of teachers’ lived experiences of conducting action research. The purpose of this research is to rethink teacher action research as Bildung, a phenomenological approach to professional development that explores the process of the teacher’s growth that is constantly evolving and becoming.
