Many teachers enter the profession with a desire to "make a difference." But given who most teachers are, where they come from, and what pressure they feel to comply with existing school policies, how can they take up this charge? Practice What You Teach follows three different groups of educators to explore the challenges of developing and supporting teachers’ sense of social justice and activism at various stages of their careers: White pre-service teachers typically enrolled in most teacher education programs, a group of new teachers attempting to integrate social justice into their teaching, and experienced educators who see their teaching and activism as inextricably linked. Teacher educator Bree Picower delves into each of these group’s triumphs and challenges, providing strategies and suggestions for all teachers along with her in-depth analysis. By understanding all these challenges, pre-service and in-service teachers, along with teacher educators, will be in a better position to develop the kind of political analysis that lays the foundation for teacher activism. This timely resource helps prepare and support all educators to stand up for equity and justice both inside and outside of the classroom and offers a more nuanced portrait of what the struggle to truly "make a difference" looks like.
