The project described in this paper adopts a decolonization-oriented, reclamation-based approach to language maintenance and revitalization. Designed and implemented collaboratively with members of the local university and tribal communities, the project involves a series of five two-hour professional development workshops for teachers of Great Basin Indigenous languages spoken in and around Northern Nevada: Numu (Northern Paiute), Wašiw (Washo), and Newe (Western Shoshone). The primary goal of the project was building capacity to support language teachers by facilitating presentations, discussions, and activities that contribute to the sharing of ideas and best practices for the promotion of local languages. These workshops were preceded by an information-gathering session to determine the interests and needs of language teachers, which resulted in the selection of workshop topics: decolonization, teaching techniques, linguistics, Great Basin history and culture, and media/recording. A diverse set of facilitators and participants were involved with the project, most of whom were members of local tribal communities. Throughout the project, the organizers remained mindfully focused on the notions of decolonization, capacity-building, and respect for Indigenous knowledge.
