A powerful tool for creating culture while, at the same time, a cognitively rigorous exercise, Indigenous-language immersion could be a key for producing both language fluency and academic success in culture-based schools. Drawing on seven years of critical ethnographic research at Ojibwe schools in Minnesota and Wisconsin, this researcher suggests Indigenous schools consider shifting from a culture-based curriculum to teaching culture through the Indigenous language. In this article, the researcher chronicles her thinking that led to direct involvement in the founding of an Ojibwe language-immersion school. Reflecting on one year of co-teaching, some of the successes and challenges of teaching in a new immersion school are articulated.
