>How do they ensure that teachers know what they're talking about?

AFAIK, they don't. There was a big fiasco recently when some guy who was teaching a C++ course was featured as "course of the week" or something, which got posted to /r/programming, and they basically tore him to shreds.

A lot of people were claiming that some of the problems were nit-picky, but there were certainly some significant issues with the code. It was the sort of stuff that someone who read C++ Primer probably wouldn't do, but someone who read "How To Program C++ in 21 Days for Dummies: the Absolute Moron's Guide" might.

The presentation was pretty terrible too, but that doesn't necessarily speak towards whether he knows what he's talking about.
