It is so critical because it opens up another lens they can see it through, as students in 2020, as indigenous learners possibly coming from a reserve, as learners in an urban setting, meaning they are going to bring a different lens to that table.

In making sure the program is effective in what it's aiming to do, which is trying to provide educational outcomes for students, the program should reflect whom it serves, not the other way around.
