I liked the Likert scale, although I’m not sure any student can even answer question 1 unless the material was prepared by someone who knew something about curriculum design. I’m not sure we will get a lot of response from the Open Ended Questions (takes more thought and time). However, as an instructor I would benefit from any of those things that students choose to answer.
We also have different types of classes - some are taught repeatedly by one or more instructors. Others are one time technique or project classes. While those questions are useful in both situations, they are particularly helpful for enhancing the curriculum of classes that are taught repeatedly.
As @Photomancer has stated, one objective of the organization is to identify sub-par instructors who either need more help, or who shouldn’t be teaching for one reason or another (repeatedly not showing up, being grossly unprepared, or something else). We all hear hallway rumors but that isn’t actionable. We can’t improve without data to use for that improvement.
Regarding questions about the instructor:
I think you will find that in some ways we are unlike other adult learners. We tend to be brutally candid - often far beyond the point of politeness. (Sad but true). Unlike the corporate environment where there are consequences for “burning” an instructor, we tend to be less sensitive to that here.
EDIT: I have to point out that someone reminded me that we are also quite tolerant of inexperienced instructors also. Which is true!
How would you suggest that as an organization we identify sub-par instructors if we don’t ask the students?
