I'm currently working through my first Udacity course (computer graphics). The problem sets at the end of each lecture are open-ended, leading to the same problem-solving pattern that I use for self-education: Google, StackOverflow, Wikipedia, etc. I believe students who complete that course will be prepared for continued self-education, unless they skip the problem sets, but perhaps other courses aren't as well designed.
