I will give it a start. Knowing that the indigenous population traditionally passes on knowledge through oral communication makes it difficult to put any kind of copyright on these types of learning environments.
When we're looking at a school per se that is addressing the needs of indigenous children through printed stories and materials, those are made available in classrooms, and students would traditionally be able to borrow such items through libraries or from teacher resources.
When we're talking about building the culture, it goes far beyond just whether or not it's a piece of printed material, because the experience I've had is that in schools right now it goes far beyond taking a piece of paper and putting it in the hands of the students. It's more of a lived cultural experience that has a lot more to it.
