In this article, Teresa L. McCarty and Tiffany S. Lee present critical culturally sustaining/revitalizing pedagogy as a necessary concept to understand and guide educational practices for Native American learners. Premising their discussion on the fundamental role of tribal sovereignty in Native American schooling, the authors underscore and extend lessons from Indigenous culturally based, culturally relevant, and culturally responsive schooling. Drawing on Paris's (2012) and Paris and Alim's (2014) notion of culturally sustaining pedagogy (CSP), McCarty and Lee argue that given the current linguistic, cultural, and educational realities of Native American communities, CSP in these settings must also be understood as culturally revitalizing pedagogy. Using two ethnographic cases as their foundation, they explore what culturally sustaining/revitalizing pedagogy (CSRP) looks like in these settings and consider its possibilities, tensions, and constraints. They highlight the ways in which implementing CSRP necessitates an "inward gaze" (Paris & Alim, 2014), whereby colonizing influences are confronted as a crucial component of language and culture reclamation. Based on this analysis, they advocate for community-based educational accountability that is rooted in Indigenous education sovereignty.
