Student evaluations are a pathetic joke, pandering to the self-entitled, helicopter parented, semi-literates graduating from today's high schools, scrounging around searching for the easiest marks.

Professors should be evaluated and coached to improve by their peers and by experts in the study of how students are motivated to explore and learn.  This can be done very simply and inexpensively.  Put a video camera in each lecture room.  No one is informed when the camera is operating so professors don't know if or when they are being observed.  Peers and experts review the footage and offer comments and, if necessary, remedial assistance.
