Book excerpt: This exploration of effective practices to support lesbian, gay, bisexual, transgender, queer (LGBTQ) and gender-diverse students in elementary, middle, and high school contexts focuses on curriculum, pedagogy, and school environment. Narratives and artwork from the field are framed by sociocultural and critical theory as well as research-based elaboration on the issues discussed. Applications of antidiscrimination law and policy, as well as learning skills like creativity, collaboration, and critical thinking help teachers tackle some of the most significant educational challenges of our time. The stories of real-world practices offer encouragement for building inclusive environments and enhancing social-emotional relationships among youth, families, and schools. Gender Diversity and LGBTQ Inclusion in K-12 Schools provides a helpful roadmap for educators hoping to create safe and empowering spaces for LGBTQ and gender-diverse students and families.
