I chose this class for a couple of reasons. First, I wanted to experience a MOOC. Second, I have had an interest in learning calculus and wanted a course that would be challenging; I wanted to put myself in the same position as my students. I have not been disappointed. This class has taught me a great deal about learning and teaching.
I think it is all too easy for us as educators to forget our purpose. Our purpose is not to dispense information. Our purpose is to help students develop understanding. My experience in this MOOC has taught me the difference.
