Diane Ravitch on NPR.
I've never heard Tom Ashbrook before, and I have no opinion. But I like to hear Diane Ravitch's voice, and I'm looking forward to reading Reign of Error. This is a good interview; she knows what she's talking about, to say the least.
Occasionally you encounter people who have genuine expertise and legitimate experience, and they're remarkably at ease with their arguments, and there's no artifice, no facade. Diane Ravitch is one of those people, and I think Karen Lewis is, too.
We should get a book group going on Reign of Error.
