We began offering an Intro to Computer Science class this fall for the first time in a long time, and I had the, ahem, "opportunity" to teach it. (We are hopefully going to be hiring a teacher for the next school year who is a bit more qualified, but just didn't have the FTE to do that this year as we got it off the ground.)
As when I taught Algebra, I asked both the students and parents for feedback via a google form at the end of the semester. I think it's always good to ask for this feedback, even though sometimes you're not sure how honest and accurate it is. Even so, I learn something from it each time.
I also think it's important to be transparent, so here are the links to their responses. These responses are verbatim, except for some slight editing where personal information was included. Both students and parents could choose to leave their name if they wished (totally optional), and some of the parent comments including their student's name - I edited all of that out.
Student Feedback (36 out of 45 completed the survey)
Parent Feedback (12 responses to the survey)
