Critical pedagogy aims to promote educational change by questioning why educational practices are done in certain ways and exposing domination and exploitation. It involves habits of thinking deeply about the meanings, causes, contexts and consequences of various subjects. Key proponents include Paulo Freire, Ivan Illich and Henry Giroux. Critical pedagogy in Canada explores concepts like "whiteness" and the impact of colonialism, like Indian Residential Schools. It also examines First Nations epistemology, pedagogy and institutions of higher education, as well as how non-Natives engage with First Nations education.
