I'm seeing the same thing as Catherine: schools love khan.I'm surprised nobody said one of Khan’s most significant achievements is that he has enormously expanded the world’s access to a master teacher.
Khan isn't going to teach k-8 kids anything, but schools love it anyway.
a) now they think they don't have to spend money on textbooks for elementary kids (first hand have heard that directly from a curriculum director)
b) now their teachers don't need to know how to do the math, khan will do it for them. (heard that directly from an instructional coach who champions Teach Like a Champion)
I know 2 other elementary teachers who love it because now they can do fun Terc things.
I only know one person who is anti Khan here in the establishment. Her very sane complaint: the man teaches completing the square without even drawing a square. It's nothing but computational and procedural fluency for him. It's the opposite of actual instruction, but now schools will use it and instruct even less.
