"Unless, for example, you are a college. Teaching computer related courses. Courses like "System Administration 101""
Too true. Over in the Chemistry department, the course on Explosives is a real blast and in the Microbiology department they have an end-of-course Ebola-snorting contest. It may be possible to teach this more dangerous content merely as book-work, but why would you do that when there is a far more effective Darwinian method of spotting the failing students?
