Weaving together concerns about environmental and social justice, Teaching as Activism brings together constructive demands for change and theoretical debate. Written by activists who also teach, the essays challenge the current pedagogical literature with proposals that would bring discussion of social and environmental responsibility into postsecondary science, the classroom, and the community. With backgrounds in feminist science and indigenous knowledges critiques, the contributors emphasize the importance of appreciating indigenous knowledges, recognizing our bias about how knowledge is presently produced, and integrating science with a human spiritual connection to nature. The goals are to question the legacies of colonialism, capitalism, and globalization and create a more inclusive interdisciplinary education.
