the “customer” is not always right

One way that university lecturers, and departments, are ranked and evaluated, is by student satisfaction surveys.  Such a customer-based model does not inevitably lead to better eduction, however, as students are not necessarily the best judges of what they have learned:

College students think they learn less with an effective teaching method
They don’t even realize they’ve learned more.

While students learned more with active instruction..., every measure of satisfaction was lower.

Personally, I prefer a “fitness instructor”-based model, where the students pay the instructor for improvement opportunites and advice (and these should indeed be as well prepared and appropriate as possible), but they have to put in the time, effort, and sweat.  No pain, no gain.
