I don't oppose improvements to education, but New York state's implementation of Common Core is worse than the old way, not better.
I didn't want to get into this here, but...
First off, it gives teachers scripts that they must follow. For this ten minutes, you need to say these words to the students in this manner and ask them this exact question using this exact example. They must answer you in this exact way. Next, you must move on to this topic in this manner. There's no room for teachers to adjust their teaching techniques to either assist kids who'd learn the material in a different way or to help advance kids who are ahead of grade level. All kids *MUST* learn in the exact same way.
Secondly, EngageNY is idiotic with math. There's no more working with numbers. If you have 1.62 divided by 0.27, you don't actually do the math. Instead, you draw 162 little boxes. Then you circle them in groups of 27. Then you count how many circled groups there are to get your answer. This doesn't teach kids how to do math and, even worse, it doesn't scale. What if the problem was 1.625 divided by 0.25? Would they need to draw over 1,600 boxes?
Thirdly, the high stakes tests are tied to teachers' jobs. If their kids do poorly, the teacher could be booted. So any chance the teacher would stray from the provided curriculum is reduced. The teacher MUST teach to the test because any time spent on non-test preparation increases the chance that their kids will fail. Add in the fact that the content of the tests is super-secret. Nobody is allowed to see them except the students taking them. Not parents, teachers, administrators. Nobody. The tests are taken, mailed to Pearson where they are graded and destroyed. Then the scores are released. How does knowing that Johnny had a grade of X help the teacher teach Johnny if you don't know what he got right and what he got wrong?
Finally, this constitutes an attempt by corporations to take over and profit from education. The big supporters of this curriculum are big corporations who will profit quite nicely over it. (Bill Gates Foundation, Pearson, Wal-Mart, etc.) I don't trust big corporations to write a "one size fits all" curriculum that will help my boys succeed. In fact, since they make more money off a kid who fails than one who passes (additional books, courses to help students/teachers/administrators, etc), they have a monetary interest in kids failing.
Don't mistake change for improvement. There are plenty of ways you can change education to improve it. Common Core/EngageNY/High Stakes testing is *NOT* one of those ways.
