Pat Phillips attended a conference on Gaming Concepts and Technologies for use in Computer Science education. She's got some information about what she learned and a slideshow with a series of interviews with educators who went on the conference. She talks about it on her blog. A lot of good links there as well.
Frankly Pat finds a ton of great information for computer science teachers. I don't know how she does it. So if you teach CS you should really make Pat's blog on MainFunction a regular read.
