Good Article Anti-Common Core

An interesting read. As a math educator, I am not opposed to the ideas proposed in the Common Core for mathematics. I am glad to see that there has been an increased focus on depth over breadth so there is time to develop a deeper conceptual understanding of the building blocks. However, to implement these changes, we will need time-you cannot drop students in upper elementary, middle school, and high school directly into the core curriculum-it should be implemented grade-by-grade.
I have only reviewed the Language Arts curriculum briefly-I have seen a sample of the PARCC and find what they expect students to be able to do in a specified time frame to be ridiculous-while what they want the students to do are noble goals, the time constraints are unreasonable. To get the depth and quality they are looking for require at least 3 times the amount of allotted time.
To me, the biggest issue with the Common Core is not the standards themselves (again, I am speaking to the math standards), but the rush to implement and the testing guidelines.
