Social media is providing new opportunities for young people to engage with gender equality and feminism. These are issues frequently silenced or rendered invisible in the institutional contexts of schools, and across?much educational policy. Offering insights into these underground practices through rich empirical examples and case studies, Gender, Activism and #FeministGirl offers new conceptual tools to understand and assist young people's involvement with contemporary sexisms, and to support new educational and pedagogical practices which can promote such engagement.
