Sexist ideologies in society are present in school curricula and contribute to children's socialization to gender norms. The problem of women's representation in history curricula is urgent as it contributes to the cycles of marginalization experienced by women. The purpose of this qualitative instrumental single case study was to describe how women were represented in California's 10th-grade World History curriculum through a critical feminist lens. This study employed critical feminist theory as the framework, supported by bell hooks' work. The constructs of critical feminist theory used were sexist oppression, intersectionality, critical consciousness, and transformative action. California was the selected site for this case study due to its status as a critical case. Data sources included California's 10th-grade World History state standards and framework, three current textbooks, and open-ended questionnaire responses from five current teachers who identified as women. These findings showed women were included less frequently than men, White women dominated the curriculum, women were restricted to certain areas of the curriculum, political and military narratives were prioritized, and participants had a critical consciousness of women's representation and made transformative recommendations for the future. Major conclusions include a need to rewrite world history standards and frameworks to incorporate women meaningfully in the future. Implications emerged for state, district, and school site curriculum decision makers in and beyond California to critically review women's representation in history curricula. Future research can replicate this study in other history courses and states and should consider incorporating more student and teacher perspectives as data sources.
