In this volume, teachers from urban, suburban, and rural districts join together in a teacher-inquiry group to challenge homophobia and heterosexism in schools and classrooms. To create safe learning environments for all students they address key topics, including seizing teachable moments, organizing faculty, deciding whether to come out in the classroom, using LGBTQ-inclusive texts, running a Gay-Straight Alliance, changing district policy to protect LGBTQ teachers and students, dealing with resistant students, and preparing preservice teachers to do antihomophobia work. Book Features: Examples of antihomophobia teaching across elementary, secondary, and university contexts, and discussions of the consequences of this work. Concrete discussions of how to start a teacher-inquiry group, and the challenges and rewards of engaging in teacher activism. A comprehensive annotated bibliography of texts that address homophobia and heterosexism.
