You should read Diane Ravitch again today.

Her latest missive in her ongoing conversation with Deb Meier is here.

Our public schools were never perfect. There was never a golden age when everyone graduated high school and learned to a high standard of excellence. Improving education and expanding equality of opportunity have been the slow, steady work of generations.

Yet now, we live in an age when it is the custom to bash the public schools, not to thank them for helping to build our nation. It has become commonplace for the president, the secretary of education, and the leaders of the business community to lament the terrible state of our schools and to demand radical, one might even say revolutionary, changes. We live in an age of data, and the data (they say) are awful. They look at NAEP test scores, international test scores, graduation rates, and anything else that is measurable, and they demand solutions, now.

Note that they never speak of the state of learning, nor even the state of education, because those words connote many intangibles that cannot be measured and converted into data. The politicians and business leaders do not speak about whether young people read in their spare time, whether their reading consists of good literature and non-fiction, whether they know how to write an engaging essay or a well-constructed research paper, whether they can engage in an informed discussion of history, whether they are knowledgeable about our governmental system, whether they perform volunteer service in their community, whether they leave high school prepared to serve on a jury and vote thoughtfully.

No, instead what we now hear from our business leaders is that the schools must be redesigned to function like business. They conveniently overlook the fact that business practices and the ruthless pursuit of a competitive edge nearly destroyed our national economy a year ago.
