The document doesn't specify that they DO apply to STEM, so that's a bit of a red herring.
I am working under the assumption that this document was well thought out and carries a lot of weight in California. Do you agree with that, or is it something just dashed off quickly and not to be taken too seriously - if say - you're a teacher at a community college?
To your comment about colonialism, which really surprised me since it sounds more like a suggestion from a politician than from an educator: In a class called "U.S. History I" where students are in a unit called "U.S. Westward Expansion", why on earth would you go off on a tangent talking about Native internecine warfare or the history of colonialism? Pedagogically that makes no sense whatsoever. Now in a class called "History of Colonialism", sure talk about comparative colonialism. Or in a class called "Native American History", sure, talk about internecine warfare. But your call to go off on tangents outside the scope of the course and the unit they're in doesn't make any sense. It's like a form of academic whataboutism.
I think it's naive to imagine that politics do not heavily influence education. As for your "US western expansion" unit, sure, if you slice it and dice it, there would absolutely be instances for which discussing mostly european colonialism took place. But we have to zoom out a bit. In THIS DOCUMENT, the subject of the OP:
- Europeans are called out several times, either as explicitly bad, or heavily implied as the bad actors of the world.
- Studying multi-culturalism is STRONGLY encouraged, but always in a positive light.
To simplify this a bit, the very clear message is: white people are bad, people of color are good.
This is identity politics at its worst. It is dishonest and needlessly divisive. It is pandering and condescending. This sort of skewing of what's important closely aligns with the goals of the woke, "social justice" culturalists. It is the opposite of diversity and inclusivity, it is instead tribal.
As for your query about intersectionality: As I have told you before, and have before provided extended examples of how I use it in my teaching, I don't have the patience to do so again here. I will say that I have published on the use of the concept in pedagogy, and that I find it useful in teaching.
I'm truly sorry, I do not recall that exchange. Do you remember the name (or keywords in the thread title), of any thread(s) where you discussed intersectionality? I will read those examples of yours! That said, I know that in these debates I am asked to repeat myself repeatedly, and I often do so. So would you be willing to summarize your stance on intersectionality?
