They are STUDENTS! Their "diverse" backgrounds, socioeconomic status, sexual identity, etc have ZERO BEARING on how you teach students. It is the ultimate racism to think you need to teach kids differently based on these factors. Imagine if you need a separate pedagogy for kids from 15 different countries, ten different backgrounds, multiple sexual orientations, marginalized kids....do the factorial analysis and you'll find you need several thousand different approaches that you can choose from to serve 25 or 30 students.
My sister was a match teacher in nearby Maryland for over 40 years and she consistently got the best results in the district because she ignored all this crap. She was demanding and set high standards. If you excelled, you got high grades. If you didn't try, didn't turn run your work, or were just plain stupid you got low grades. The kids complained all the time, but my sister often heard from kids she taught 10 or 20 years earlier and they all thanked her for being tough but fair. They always said that they tried harder in her class than any other.
It's not rocket science.
Four years of college and huge student loans and they are not prepared to teach anyone. What were they doing? Frat parties?
In the immortal words of Dean Wormer “Fat, drunk and stupid is no way to go through life.”
“It is the ultimate racism to think you need to teach kids differently based on these factors.”
Absolutely. Teach to bring students up, not down. This exemplifies the incompetent culture of the left that brings society down.
