I'll also have the students interviewing participants much like we did at Alan November's Building Learning Communities conference this summer. That was a fantastic experience where our students rubbed elbows and interview many of the movers and shakers of the educational technology community like Marcos Torres, Marc Prensky, Chris Lehmann, etc. (Check out some of the interviews here.)
Also, here's the keynote presentations from the 2006 ACTEM conference.
