I saw a study somewhere in which graduates were asked what turned out to be their most important law school courses. Wouldn't it make sense to do the same thing with teaching evaluations? Students can know who make the hour pass quickly, who "gave good notes" (as I have heard it called) but can they know who was the most effective in preparing them for life after law school. I doubt it. Plus there are those studies from other fields that show all kinds of relationships, including inverse, between evaluations and learning. Has any school attempted to corrolate the numbers on the evaluations with test performance.
So, here is a survey. "Verified" means some independent effort to determine whether the student know what they are talking about.
