Most semesters I give my students the opportunity to comment on my teaching and the course through the standard anonymous departmental evaluations. Lately I have thought that it would be worthwhile to let the students see both what their classmates have said, and what previous classes have said. I will therefore gradually be posting my student's evaluations of me here in their entirety (both the favorable and unfavorable ones).
(Note: Please do not complain to other professors if/when they do not do the same thing!)
