Marginalized knowledges are the intergenerational knowledges and skills from communities worldwide that hegemonic forces have pushed to the margins of society. These include facts, beliefs, perceptions, attitudes, behaviors, and competencies. Marginalized knowledges are part of the human capital that materially poor rural and urban peoples have developed over time—both Indigenous and non-Indigenous communities. These knowledges are situated and contextualized in a given time and locality, and have evolved to fulfill economic, social, environmental, spiritual, or cultural needs. School systems worldwide in the 19th and 20th centuries adopted an official, hegemonic curriculum that ignored and displaced these vital knowledges at a great loss to poor communities. Fortunately, different pedagogies exist today (e.g., pedagogy of place; funds of knowledge; civic service) that seek to bring these knowledges to the center of school life and provide a complementary, parallel role to that of the school’s official curriculum.
