I took a look at your thread from last year. I would say that you were discussing indigenous WISDOM (which I think is a good thing), but I don't think what you were describing is SCIENCE.
Yes, that's precisely the sort of cultural bias that was discussed in the seminar I went to. You would have learned a lot from it, perhaps.
But in STEM topics?????? Please give me a few examples of how these DEI ideas would improve STEM teaching.
Well, I already gave you the one. As someone who included a study of the philosophy of science in their master's program, really examining what we do and don't consider to be "science" - and the cultural biases that come with how we view it in the West - is beneficial if not essential. When I think about the fact that my philosophy of science coursework didn't even cover that, today I consider it a massive oversight. We can (and should) do better. University is all about deepening and broadening our intellectual horizons, so representation of diverse cultural understandings of the world is part and parcel with what university IS. I could see it being a bit overly-complex for lower levels of education - maybe start getting into that during high school at the earliest - but it is very appropriate for university.
