For the Tsleil-Waututh nation, there is not as much information readily available. One part of their traditional teachings that I was able to find was that it has to do with their relationship with the local ecosystem and its resources. This is a key part of how culture that is taught by the Tsleil-Waututh nation. In fact, the younger generation was taught while actually doing the harvesting and processing of materials, so experiential learning is a key principle. Another point of interest is that traditionally, the women were the teachers as they were the keepers of knowledge.
