re: MIT Sees Zombies And MOOCs In Education's Future
I probed on that same point. What people told me is that the three-dimensional audio, the ability to hold conversations that are much like you could have at an actual seminar, changes the dynamic in an important way. I agree that it seems like a small thing, but we've all seen an iterative change transform a failed technology into a groundbreaker. I'll see if Erik Brynjolfsson will comment on this.
It also is a system designed for collaboration, so it's more focused than Second Life. I'm going to file something today about MIT expanding its usage of this system, so we'll have a better sense of its effectiveness over time.
