What’s wild is people who haven’t taught thinking they know better than people who do teach.
In particular, I'm curious how you come to the conclusion that high-quality video content cannot work better for "the vast majority of students" than sitting in a lecture hall. Do you have any theories about what kind of student good video content can work well for?
I didn’t make this claim. I said that videos like 3Blue1Brown’s videos would not work in the classroom for most students. I further said that there was a reason things are done the way they are.
Imagine going to a place of business and seeing people doing their job. A job you’ve never done before. You start giving advice on what they should do. Most likely your views would not carry much weight or be worth much consideration.
