William W. Fisher III, a professor at Harvard Law School, has been experimenting with ways to split the difference. This spring, Fisher is teaching his first online course, CopyrightX, through edX. But he’s also a casual student of the medium. Fisher’s field is intellectual-property law—he was among those to represent Shepard Fairey and his “Hope” poster—and he works a lot on rights in the digital age. I met him one morning in his office, which had a standing desk and an ergonomic keyboard in one corner. At one point, Fisher’s Portuguese water dog, Nica, wandered in. He explained to me that he has reservations about MOOCs.
