Although recent scholarship has examined gender issues in Judaism with regard to texts, rituals, and the rabbinate, there has been no full-length examination of the education of Jewish children in day schools. Drawing on studies in education, social science, and psychology, as well as personal interviews, the authors show how traditional (mainly Orthodox) day school education continues to re-inscribe gender inequities and socialize students into unhealthy gender identities and relationships. They address pedagogy, school practices, curricula, and textbooks, as along with single-sex versus coed schooling, dress codes, sex education, Jewish rituals, and gender hierarchies in educational leadership. Drawing a stark picture of the many ways both girls and boys are molded into gender identities, the authors offer concrete resources and suggestions for transforming educational practice.
