Diane Ravitch gave a speech at Rice University about school reform in which she directly challenged officials from Teach for America and the Knowledge Is Power Program who were present -- the very people who had invited her...Her speech starts at about the :10 minute mark and ends at about 1:02. The question and answer period after the speech is poorly produced and difficult to listen to. This is definitely worth the hour time investment to listen to her even if you choose not to suffer through the last 20 minutes of questions and answer.
Point by point, she picked apart school reform measures pushed by the Obama administration, leaving no topic untouched: charter schools, value-added teacher assessment, punitive sanctions on low-performing schools, No Child Left Behind, how Finland became an educational model by supporting teachers in ways the United States doesn't, the Texas educational miracle that wasn't, etc.
