I have mixed emotions about these massive open online classes. The homonym MOOK (yes, they are really called MOOC’s) comes to mind. But, then I recall the first biology and microbiology courses I took. At one school, where the total enrollment (including night school) was under 4000 in all degree programs, there were 300 kids in this class. In another institution, where the enrollment was about the same (but more prestigious, and no part time students), and there were 250 in the other.
