This is the required core course for the university-wide graduate certificate in Gender and Sexuality Studies and it is open to all the graduate students who are interested in sexuality and gender studies. Our starting point is the acknowledgement that sex- and gender-based modes of social organization are pervasive and, further, that their prominence and persistence are reflected in sex- and gender-conscious research across the humanities, the arts, the social sciences, design, and studies dedicated to social policies and innovative strategies for social intervention. We will expand on this starting point through both an in-depth survey of influential theoretical approaches to sex, gender and sexuality such as Marxist feminism, Black feminism, Native and Indigenous feminism, transgender studies, queer theory, and postcolonial and decolonial feminism, and by paying attention to the significance of different approaches. Topics to be explored include, but are not limited to: intersectionality, coalition and liberation, ecofeminism and Queer Ecology, equality and rights, exploitation and the division of labor, the construction of gender, performativity, gender images, narrative and identity.
