This week's Chronicle of Higher Education has a number of interesting items, amongst which is an article describing Texas A&M's introduction of bonus payments based on teaching quality based on student evaluations. Needless to say this has not been lacking in controversy.
The other, slightly lighter item is that one US professor has a novel way of keeping students awake in class. He has replaced the chairs in class with exercise/pilates balls! Nodding off could result in a severe headache as you crash to the floor.
