Last fall of 2011 Peter Norvig, a leading American computer scientist and Artificial Intelligence expert startet a virtual class along with his college Sebastian Thrun on artificial intelligence. the class was visited by 175 students from Stanford and more than 100,000 via an interactive webcast. Peter Norvig is talking about the fact that we are teaching knowledge in classes with the same methods today as we did hundreds years ago. So he argues that today we have the possibility to change the way we are teaching and that we could produce a lot more positive educational effects with our modern infrastructures. Watch his really interesting TED talk about his experiences with this 100K classroom.
