The article reviews *Dude you're a fag: masculinity and sexuality in high school* by Cheri Jo Pascoe, analyzing how masculinity and sexuality are constructed in high school settings. Pascoe uses ethnographic methods to explore how boys and girls navigate gender roles, with a focus on interactions, discourses, and traditions like sports and prom. The study, conducted at a California high school, highlights how masculinity is often tied to heteronormative practices, with boys reinforcing male dominance through rituals. Pascoe examines themes such as repudiation of femininity, confirmation of masculinity, race, homophobia, and girls' strategies for navigating gender norms. She challenges the notion that masculinity is solely tied to the male body, instead proposing a socially constructed model that includes both male and female practices. Pascoe critiques schools for reinforcing heteronormativity by rewarding traditional behaviors while punishing non-conformity. She argues that parody and play, while important, are not inherently progressive and can reinforce gender boundaries. The reviewer suggests that focusing on the agency of marginalized groups, such as the basketball girls and Gay-Straight Alliance (GSA) girls, would be more effective in challenging heteronormativity. The reviewer also emphasizes the role of teachers in gender socialization and calls for teacher training to address heteronormativity. Pascoe concludes by advocating for practical steps to promote equity in schools, such as curriculum redesign and support for GSAs. The reviewer finds the book insightful and recommends it for researchers, educators, and students interested in gender and sexuality in education.The article reviews *Dude you're a fag: masculinity and sexuality in high school* by Cheri Jo Pascoe, analyzing how masculinity and sexuality are constructed in high school settings.
