Book excerpt: bell hooks—feminist scholar, teacher, activist—implored instructors to see the classroom as a “radical space of possibility” where students and teachers work as partners in the pursuit of education as “collective liberation” from structures of domination. hooks’ call takes on more urgency today, as oppressive and dominant ideologies continue to perpetuate racial, economic, gender, and other social inequities both within the classroom and society at large. Through critical commentary reflections on classroom experiences and original teaching activities, the authors in bell hooks' Engaged Pedagogy for the 21st Century Classroom: Radical Spaces of Possibility provide inspiration for teachers with the will to learn and the courage to teach about intersecting systems of oppression in meaningful, radical ways. The goal of this collection is to carry forth hooks’ legacy of education as freedom and to serve as a guide that renews faith that “teaching to transgress” racist, sexist, and classist systems of oppression is not only possible, but is a first step in transforming the world.
