Seventeen years ago Gloria Ladson-Billings (1995) published the landmark article "Toward a Theory of Culturally Relevant Pedagogy," giving a coherent theoretical statement for resource pedagogies that had been building throughout the 1970s and 1980s. I, like countless teachers and university-based researchers, have been inspired by what it means to make teaching and learning relevant and responsive to the languages, literacies, and cultural practices of students across categories of difference and (in)equality. Recently, however, I have begun to question if the terms "relevant" and "responsive" are really descriptive of much of the teaching and research founded upon them and, more importantly, if they go far enough in their orientation to the languages and literacies and other cultural practices of communities marginalized by systemic inequalities to ensure the valuing and maintenance of our multiethnic and multilingual society. In this essay, I offer the term and stance of "culturally sustaining pedagogy" as an alternative that, I believe, embodies some of the best research and practice in the resource pedagogy tradition and as a term that supports the value of our multiethnic and multilingual present and future. Culturally sustaining pedagogy seeks to perpetuate and foster--to sustain--linguistic, literate, and cultural pluralism as part of the democratic project of schooling. In the face of current policies and practices that have the explicit goal of creating a monocultural and monolingual society, research and practice need equally explicit resistances that embrace cultural pluralism and cultural equality.
