This book provides a research-based guide to using ePortfolios to develop critically reflective teachers capable of transformative learning for educational equity. It begins with a conceptualization of critical reflection in teacher education, then analyzes the social discourse of prospective teachers' teaching practice through their ePortfolio reflections, triangulated by classroom teaching observations and interviews. The results of the research show that prospective teachers' reflections are performative and do not typically trigger transformative learning, in large part because of discrepancies in the structures of the ePortfolio, the goals of the teacher education program, and the mentoring and supervisory practices. With this analysis in hand, the book turns to practical questions, providing a transformative framework along with examples and tips for teacher educators to use the author's methods to understand and analyze prospective teachers' reflection and support their transformative learning.
