Like many institutions, the University of Michigan was inspired by the early aspirations of the massive open online course (MOOC) movement to democratize education and, in our case, to advance our mission as a public research university. We thought better of a big toe dip, saw reason for a deeper commitment to experimentation, and dove in head first for a swim. Many pushed for swimmers to pick a stroke and stay in their lanes. We prefer the flexibility of freestyle and open swim.
