This idea has been developed and deployed to Canvas
Right now, we have the option to "Let Students See Their Quiz Responses," but that's not exactly what the setting does. I would like either for this setting to do what it says or for the label to be more accurate.
This setting doesn't let students see just their responses, it lets them see how their responses have been scored (see comment below). A more accurate label might be "Let Students See Their Graded Quiz Responses." I was confused by this label originally and only learned the hard way what it does, and I believe others have been in this same situation.
Because this setting currently shows not just the students' responses, but also whether the responses are correct or not, students who see their own quiz results also learn the correct answer in these situations:
when the question is true/false
when the student has correctly answered a question
when the general comments hint at or explain the correct answer
And for multiple choice and matching questions they have at least narrowed down the options. That's too much information to release to a class while the quiz is still available. Therefore, when I create a quiz, I don't check "Let Students See Their Quiz Responses." However, after I have finished grading the quiz, with this setting they can't see any comments on their graded questions, so I then need to return to the quiz settings and allow students to view their responses. Having to return to the settings screen is a huge pain in the neck and sometimes I forget to do it. When I forget to do it, students can't see the comments that I painstakingly enter on their quizzes, and then they (and I) get frustrated. And when the quiz is imported to a new course next semester, I have to remember to go back and change this setting again.
Release answers button for quizzes This idea (I think) would solve the problem of having to change the quiz settings after a quiz is graded, but it doesn't address the use case posted to the old feature request forum.
My preference would be for the setting label to do what it says, but if that's not possible, please change the label to say what it does.
