Especially as we leverage both in person and virtual learning, it feels a bit arbitrary to me that we only teach things that require between 30 and 75 hours of instructor led instruction (15 weeks in a semester x 2-5 hours per week). I look at the world of professional education where we might take a class on "effective negotiation" that might be 4 hours of instructor led material. I think there is a world of material that could be VERY useful if we can teach classes that have smaller units. Virtualization and asynchronous instruction allow us to do things that economies of scale in the physical world did not.
