Of all the responses to Arne’s Duncan’s announced resignation from the Department of Education, Diane Ravitch’s has the most succinct and incisive:

“In the car yesterday, I heard a report that Arne Dyncan was stepping down. President Obama said: He did more than anyone else to bring American education into the 21at century, sometimes kicking and screaming.

“I am paraphrasing but that is a very close approximation of what he said.

“So this is what the 21st century will look like: boot camps for minorities; teachers with scripts; schools run for profit; school scams by corporations; education industry traded on the New York stock exchange; high-yield online schools with high attrition rates; the monetization of public education.”
