Gonaowoo K'ee
Gonaowoo K'ee or "Our Ways" courses focus on teaching senior high students Tłı̨chǫ knowledge and skills traditionally passed on from generation to generation. This acquired knowledge and skill base will assist students in sustaining the Tłı̨chǫ way of life as the young community members become prepared and are highly encouraged to live an active life out on the land. These skills are taught in the natural environment, using Elders, guest speakers, and community members who are strong in their culture. Some module activities include: hunting and trapping, fishing, traditional tool making, and Tłı̨chǫ history and politics. It is currently team taught by Ernestine Steinwand, Chris Stanbridge. Phillip Mackenzie, and Cultural Educational Assistant Joe Mantla.
