The Washington Monthly's ranking of universities (which I learned about, of course, on the Colbert Report) is based on outputs, not inputs. But it may be no less problematic. The magazine counts the number of PhDs and the number of graduates who enter the military - not exactly the counts that remind one of learning. And in the same vein, Tony Karrer summarizes numerous articles that look at Return on Investment (ROI) and e-learning. Equally a morass. Measuring learning is still like measuring friendship. You can count friends, or you can count on friends, but not, it seems, both.
