The H'a H'a Tumxulaux Outdoor Education Program is a land-based project of the Kootenay-Columbia Learning Centre in Trail, British Columbia (B.C.). 'H'a H'a Tumxulaux' means "Sacred Land" in the language of the Sinixt people, who claim lands in the West Kootenay region of B.C. as their traditional territory, amongst other Nations. The program is offered in an alternative educational setting and is targeted towards students ages 12-15, many of whom experience a variety of social, emotional and mental health challenges, and who have either tuned out and/or dropped out of conventional school programming. About half of the students in the program identify as First Nations and Métis, drawing roots from a variety of Indigenous communities. This case study report examines how three key components of an Indigenous-centred program -- land-based learning, spirituality, and the Medicine Wheel -- have created a template for student engagement and retention. Through these components, this report proposes recommendations for educators and administrators tasked with integrating Indigenous Worldviews into the classroom.
