My my my! I learned (a few weeks ago) about the Coursera wiki. It seems like a really nice feature of the Coursera platform. People can go in and edit, revise, add, delete just like a regular wiki. There is a page for all the courses – and so to the extent the coursera community learns about it, the wiki might be a really nice (and lasting?) resource on the courses. I don’t see this wiki page explained or advertised too much in the courses I am enrolled in – but it does look like the Model Thinking page has some information on it. It will be interesting to see how that develops!
