Overall supportive, although individual lesson plans might be tweaked.
I'm very supportive of the concept of a national curriculum though. One even more stringent than Common Core.
Math and history are the same everywhere. There is no reason kids in Texas and kids in New York need to learn differently.
As far as I can tell, there are only two types of opposition: 1) Religious fundamentalists who are worried about evolution and gays 2) Teachers who don't want to be held to any standard and just want to be paid automatically. I guess there's a third group of people, parents like Louis CK who are mad that their kids are dumb and blame Common Core, although they would blame whatever the current regime was as long as their "genius" kids were failing under it.
I dispute this. History ought to have a local component as well.
