The purpose of end-of-course surveys is to have feedback on the course overall.
However, the survey is more of an evaluation of the instructor than the course itself. A successful course depends more on how a student approaches it than how the instructor does. Obviously, most of the time a bad instructor implies a bad course even for students that have a commitment to their studies. Similarly, a student that takes a course without putting in the effort/hours required for a college course and still has a "high-school" mindset, will evaluate the course negatively.
I'm allowed to add questions to the survey and plan to do so in a way that gives students the opportunity to reflect on the responsibility they had to succeed in the course they are evaluating. Hopefully, some of them, will take ownership of their learning and approach college in a different way.
With this in mind, what are good custom questions to add to an end-of-course survey?
