I was in the the AI class mentioned in the article, and I can say the results were somewhat disastrous. The early problem sets were trivially easy to facilitate quick grading (e.g., creating truth tables for propositional logic statements, filling in two variable names in pseudo-code for a search algorithm), while later problem sets had enough errors to make completing them difficult or impossible. Incorrect and conflicting information was regularly given out at office hours, assignments and tests were graded incredibly slowly and rarely returned, and the professor and T.A. were almost never on the same page. I understand the difficulty of the situation for the professor and T.A., but as a student I often felt I was wasting my time.
