Wayne said, re Coursera's restricting rights of assessment:
In practice, learners don't read the fine-print of TORs until they need it.
That is one of many reasons why we need to keep pressing and modeling the message of "open" as a broad ethos about learning and sharing on the web, rather than in the limited and potentially confusing senses used by organizations like Coursera. Here's a great video interview with Audrey Watters, Philipp Schmidt and Jim Groom on getting back to "open."
