Is a MOOC more like a book or more like an event. It's an intriguing question and it's raised by the emergence of book-link MOOCs in recent years. But Dave Cormier comments, "More and more I see any MOOC as an event. It's an event in which you can participate in whatever way you like. The social (and financial) contract explicitly at the core of most courses doesn't exist. While this may lead to some of the low rates of completion that are part of what a MOOC is, they allow for flexibility of participation. The MOOC as 'textbook' is one of those methods of participation."
