If you've ever actually taught an online course, the thought of teaching a MOOC sounds like an absolutely crazy idea. It's hard to get past the idea that you might be multiplying all your ?online student? headaches by a factor of 100 or 1000. Well, those were my first thoughts about it too. However, what I learned was that teaching a MOOC has been the purest and most fun form of teaching and learning that I?ve ever done. Teaching a MOOC is a complete paradigm shift from traditional education in terms of the design, the assessment requirements, and the diversity of students. As the manager of courses for Canvas Network, we?ve learned a lot about how to design a good online course for students who struggle with English, span all the time zones in the world, and have very different learning goals. In this talk I will share my own teaching experiences and surprises and some of these design tips from our MOOC courses.
