Daniel Bonevac teaches philosophy at the University of Texas. Our youngest son, Chris, who has majors in classics and philosophy, is currently taking a class with him.
Bonevac taught a Massive Open Online Course (MOOC) to 35,000 people! He mentioned in the interview below that a Stanford class on artificial intelligence had nearly 170,000 folks enrolled!
I am not sure yet what to think about MOOCs, but it does seem to be the, or a least a wave of the future.
