An interesting interview. He’s being a little too politically correct here, though:

…in the 21st century we need teachers who teach math and science to have expertise in math and science. So there needs to be an upgrade there, and refocus on how much we value those teachers. As you know, in this country, we don’t pay our teachers all that well. We need to rethink that.

The problem isn’t that we don’t pay teachers well, at least on average. The problem is that we don’t pay the valuable ones enough, and we pay the worthless ones far too much, thanks to the unions. We need to be able to adequately compensate the teachers who have actual useful knowledge to impart, and get rid of the ones who don’t. This would all start by eliminating the worthless, or to be more accurate, negative-value, “education” major.
