Here's a tantalizing tidbit:
Gates: “Does she like the status quo?"
Ravitch: "No, I certainly don't like the status quo. I don't like the attacks on teachers, I don't like the attacks on the educators who work in our schools day in and day out, I don't like the phony solutions that are now put forward that won't improve our schools at all. I am not at all content with the quality of American education in general, and I have expressed my criticisms over many years, long before Bill Gates decided to make education his project. I think American children need not only testing in basic skills, but an education that includes the arts, literature, the sciences, history, geography, civics, foreign languages, economics, and physical education.
"I don't hear any of the corporate reformers expressing concern about the way standardized testing narrows the curriculum, the way it rewards convergent thinking and punishes divergent thinking, the way it stamps out creativity and originality. I don't hear any of them worried that a generation will grow up ignorant of history and the workings of government. I don't hear any of them putting up $100 million to make sure that every child has the chance to learn to play a musical instrument. All I hear from them is a demand for higher test scores and a demand to tie teachers' evaluations to those test scores. That is not going to improve education."
