People are resistant to change even when they say they want change (politics is a great of example of wanting "change" but having a fit when things actually change).
I have no problem with showing kids different ways to conceptualize a problem, but marking 5 x 3 = 5 + 5 + 5 wrong is just madness.
I feel like there is some deeper cultural problem afoot. Why don't educators get the benefit of the doubt that other professions are given? I never hear people decry the way in which their doctors are going about their doctoring!
On a practical level, people understand adding but they don't understand how the endocrine system interacts with the immune system and how diet affects that interaction.
If it makes you feel any better, the programming profession isn't much better.
Personally, I love educators for sticking in there, but:
1. There has been basically no major disruption in this field in at least a hundred years. I have a hard time thinking of another field like this.
2. I have no confidence that changes would happen even if someone figured out how to teach kids twice as well with half as many teachers.
3. Educators, as a community, aren't exactly scientific. For example, many of them push for universal pre-K, which isn't exactly settled science.
It doesn't matter if its stupid or effective, there's a common theme of very early adult learning experiences such as military basic training, young doctors 36 hour shifts, apprentices in the crafts, where something akin to hazing turns teens into productive adults. So you do pushups in the mud until you puke, suture lacerations until you collapse asleep, and sweep floors and other grunt work for your first months with the journeymen and masters. Programmers haze noobs by forcing them to recite algorithms in whiteboard interviews.
Now I emphasize that its probably a stupid way to train a doc or a plumber or an attack helicopter mechanic, but its just how we haze while telling ourselves its learning, and wrapping it all up in layers of rationalization. And for parents, critically its the most recent example of learning. Even if their own school experience didn't suck, their internship or apprenticeship or basic training sure did, and that's how its supposed to be, in an abused grow up into abusers mentality.
So "obviously" the kids need to do timed arithmetic worksheets for hours until they cry, or stay up half the night writing essays the teachers won't read anyway. That's what "real learning" is all about, right?
Also, the idea of homework is that the kid will try to learn the material at home and parents will help. If you remove that, you put more pressure on the teacher to teach them the things they are supposed to know. You've already got them testing or preparing for tests for a large part of the day, teaching them things is really going to cut into watch-a-video time.
I hated math in high school, mainly because of how it was taught to me. Even as someone who was a proliferate reader and was quite inquisitive, I never realized just how much I was missing until college. By the time I experienced math and got the chance to see the beauty in its concepts, I had effectively wasted years dealing with formulas and memorization. Even now, I get angry when I think about how poor my math education was and everything that I didn't get a chance to enjoy at the time. And that's coming from what was a pretty good school district. I shudder to think how much worse my experience could have been at a bad one.
Anyhow, what are you talking about with Common Core? CCSSI wasn't written by politicians. It was written by subject field experts. Teachers had a great deal of input, but in general, teachers can only offer anecdotal data. You need to take that anecdotal data, combine it with findings from educational researchers who have undertaken rigorous research using the scientific method, and use that data to guide subject field experts in developing educational standards. Especially for elementary education, where teachers have to--by definition--be more generalists than anything else. Common Core did that, and every analysis I've seen over the past few years supports the conclusion that they're a significant improvement over previous state standards.
Most of the arguments against Common Core are either largely political themselves or significantly misinformed about what Common Core is. The ones against the math standards in particular can largely be summed up as "you're doing it differently than I learned it." No shit. That's the point. And the arguments against state and national standards are particularly amusing, as if fucking math changes based on the state you're in.
