Should a professor discuss his/her reviews (given by students) in class? The question is inspired by this image posted on reddit. Would this be considered a constructive step towards improving the interaction with students and the teaching in general? To clarify, I am talking about the reviews that the department or college solicits from students towards the end of the course, aka student feedback.
When I was teaching at a German university and we received course feedback, we were required to inform the students about the feedback. So while the feedback was anonymously given by each student (online), the students should get general feedback on how the course was evaluated. For some that meant simply sending the questionnaire summary to the students, but many discussed the evaluation in the last lecture.

For me it made sense to discuss the results:


You get an opportunity to thank the students for positive feedback.
You get an opportunity to clarify contradicting or unclear feedback (e.g., talks to fast vs. talks to slow).
You can also address 'below the belt' feedback. I think you can say anything if you do it with respect. And giving feedback -- even highly critical feedback -- with respect is something that students should learn, if only to prevent huge problems in the future where a lack of respect is ... less tolerated.
You can show students how to constructively deal with feedback (if you can deal with feedback). I think you should both take the feedback serious and add some humor (i.e., take yourself lightly but the job seriously). Otherwise, you are not only alienating the current students but also future students.
You can get feedback in the very last lecture. In some courses, the feedback was requested during the phase with the highest stress levels. Students only saw what they had learned and how they had benefited later.
