Peter DeWitt, in his outstanding blog at Education Week, pulls apart Secretary Arne Duncan’s aggressive defense of the Common Core.

In his speech to the nation’s new editors, Duncan ridiculed the critics as though they were almost all paranoid nuts.

That is unfortunate.

Reasonable people have legitimate concerns about how the Common Core will work, and Duncan would do well to address them.

Some are worried, as DeWitt is, and as I am, that the Common Core tests will widen the achievement gaps.

He is concerned, as am I, that the chanting about rigor, rigor, rigor, does not take into account the kids who are already struggling.

He has vastly over promised what the standards are, what they will do, how they will affect children and schools.

If would be good if he knew, but he doesn’t know.

He has enlisted leaders of the business community as cheerleaders, but they are not the ones who will implement the standards.

These “national standards” have been imposed from Washington with no field trials, no demonstrations, no means of adjusting what goes wrong.

I am not going to get exercised about them because my guess–as a historian–is that we (or someone) will look back 20 years from now, and someone will say, “Remember those Common Core standards?”

And the answer will be “huh?”

The reasons?

The standards were rushed into place with minimal participation by those who must implement them.

Many states lack the technology and the bandwidth to implement the assessments.

From what I have seen in New York, the Common Core assessments are too long and developmentally inappropriate.

Many teachers have not had the professional development to do what is expected.

The U.S. is in a period of reform fatigue.

There is just so much that can be accomplished at any one time.

With so many states changing so many things, it is all more than any system can handle at the same time.

To do national standards right, the process should be done right, with more inclusion, more participation, more feedback from those in the classrooms of the nation, more willingness to listen and get it right.

More wisdom is needed to engage in this process.

We have seen a rush to get it done without regard to the implementation or the consequences for children.

It doesn’t help to ridicule those who raise questions.
