"Pseudoteaching" - brilliant lectures can (and often do) involve this, according to Frank Noschese

Frank Noschese writes incisively - with reference to Walter Lewin's gripping introductory physics lectures at MIT - about about why a lot of apparently excellent teaching is nothing of the sort:

"The key idea of pseudoteaching is that it looks like good teaching. In class, students feel like they are learning, and any observer who saw a teacher in the middle of pseudoteaching would feel like he’s watching a great lesson. The only problem is, very little learning is taking place."

Noschese has several pseudoteaching links on his blog, and a useful RSS feed that aggregates comments on his blog relating to pseudoteaching.
