John's forte was the development of Learning Games, based on Powerpoint and some more sophisticated Flash based content. He took attendees through some of the games including "Battle Of The Sexes" (useful only in co-ed schools), "Millionaire" and several others. He also talked through the use of these games as templates for students to create their own versions, easily tying these platforms to whatever learning was current in their classroom. There are a number of examples on John's website at My Interactive Classroom. He also talked through his pedagogical stages of IWB use - which you can find here in a comment on Lauren O'Grady's blog.
John let his games do his talking for him by getting audience members involved in the games. He was witty, informative and flicked onto a new example before the audience could get bored, which is an excellent tactic for any classroom.
In my mixed bag experience at this conference, John's session was a standout.
