MIT’s Open Course Ware project is designed to bring some of the excellent teaching materials developed by MIT to the world free of charge. I just noticed that they have hired some people to translate the sites into Spanish and Portuguese.
I actually use OCW sometimes to look up things in lecture notes. It seems like the structure is too restrictive to cover some classes, however. I guess the lecture notes/problem sets/midterm paradigm is dominant at MIT that OCW can have wide coverage if not universal coverage. If only Berkeley’s educational IT support was so organized. Some might argue that it’s a functioning chaos. I find it inefficient and wasteful.
