The Gender Equity Movement in Schools (GEMS) program was initiated to promote gender equality and reduce violence by engaging students in critical thinking and self-reflection. GEMS builds on successful efforts in India, such as Yari Dosti for young men and Sakhi-Saheli for young women, to foster more gender equitable attitudes and behaviors among youth, using group education activities (GEA) to engage students in the school setting. Participatory methodologies engage students in relevant interactions and reflection about key issues of gender and violence. This manual is based on the experience of conducting GEA with students. It is organized in seven modules, each corresponding to a specific theme. The GEMS experience provides evidence of a useful and feasible methodology for creating discussion around gender equality within the school setting.
