Schools are unique institutions where structural and cultural dynamics shape the actions of humans. Power is everywhere, and the structures of schools channel power in ways that shape the identities of teachers. Yet, teachers find ways to challenge existing dynamics and in their confrontations with power can create new ways of being. This study uses a grounded theory approach to analyze interviews and observations of seven New York City public school teachers. Emerging from their words and re-tellings is a picture of teaching as an act of self-creation within the rigid dynamics of schools. As teachers sought their own answers, they showcased a transformative growth, a "becoming," to build new identities through their work with students and the community.
