This edited collection illustrates different possibilities for social justice practice in various grade levels, disciplines, and interdisciplinary spaces in P–12 education. Chapters in this unique volume demonstrate teaching with a critical lens, helping students develop critical dispositions, encouraging civic action with students, and teaching about topics inclusive of race, class, gender, and sexuality. Based on empirical research, each contribution is rooted in a critical theoretical framework and characterizes findings from sustained study of pedagogic practice, spanning subject matter from social studies, English Language Arts, music, mathematics, and science. Through this work, both pre- and in-service teachers as well as teacher educators will be inspired to practice social justice in their own classrooms.
