Uh… I forgot. Rich Vogel isn’t presenting because, sadly, his dad passed away recently. 😦
Sasha Barab is now presenting in his place about Reflexive Play Spaces: Narratizing Disciplines and Disciplining Narratives. Games are different than simply contextualizing problems a la PBL in that players role-play characters that actually change the world. The context is dynamic rather than static. “Reflexive Play Space is a form of ‘transactive art.'” See the Quest Atlantis stuff for more info.
Anyway, all of the sessions are being recorded. Not sure where they will be online but they will. I’ll pop in a link to them as soon as I find it.
