I would like more accountability from professors somehow. Maybe not from student reviews, but at least someone unknown to the professor randomly attend a few classes to check the quality of them. Right now I have a professor that says things during class that are obviously incorrect, and can be verified as incorrect. Her attitude towards students is also disrespectful. But there is nothing we can do about it, no way…
But I'd start with laying out concrete things, rather than "embarrassed and ashamed".
