@Diane,
Very interesting. But I am very skeptical. I watched much of the video and it is interesting. But it goes against other research that shows the failure of computer based learning.
One question is how to make sure the "mid-kids", that is the majority of kids who aren't super motivated or assertive, learn. In a classroom the natural state of things is for a few very bright and strong-willed students to dominate the classroom. They end up doing all of the work and their ideas are the ones that get tested. Obviously this is not a good thing for the majority of class (and not surprisingly this is one of the reasons that girls do better in gender segregated classrooms).
A good teacher recognizes this and part of creating an effective learning environment is setting up a classroom culture where everyone takes parts. Kids aren't going to do this naturally.
This might be valuable to a small number of exceptional kids, but humans evolved to learn in social groups.
I would like to know if his experiments have been critiqued.
