Canvas: Showing Quiz Answers to Students
Note: This information relates to the current Canvas Quiz tool, not New Quizzes, which is currently available but not yet standard Canvas functionality.
There are several ways in Canvas to show students the answers to a Canvas Quiz, but they all have implications for quiz security or instructor workload. In all these cases, because the key is out there, the quiz can be shared with future semesters' students. You will find more information on Canvas Quiz settings to maximize Security, but this article focuses on understanding your options for showing answers.
Option 1 - Easy workload, security problems
Set up the dates so no one can take the quiz after a certain date and release the correct answers after that date. However, after students take the quiz they will be able to see all their questions and all their answers, and the answers will be marked correct and incorrect (correct answers for incorrect questions will not show until after the quiz is no longer available). So the correct answers can get out before the quiz is done.
Option 2 - Easy workload, security problems
Set up the quiz so that students can see their answers and the correct answers only once, immediately after the quiz. Once they leave the page they do not get to see their answers again, but again answers can get out before the quiz is closed. If you are having students take the quiz online in a proctored room, this might be a good option.
Option 3 - Increase workload, quiz secure during semester
Set the quiz so students cannot see their quiz responses and set an Until date that prevents students from taking the quiz after a certain date. Students will be able to see their scores but not their correct and incorrect answers. On that date and instructor can go into settings and check the box to allow students to see the correct answers between certain dates. Correct answers can not get out during the quiz, but might be passed to future students. When starting up a new semester, and instructor would need to uncheck that box for all the quizzes. (Settings before on the left, after on the right.)
Option 4 - Increase workload, quiz secure during semester
Create a document with the key and have it in modules unpublished. After the quiz Until date, publish it. When starting up a new semester, and instructor would need to unpublish the keys for all the quizzes.
For ultimate security for quizzes, the best option is to never let students see the quiz responses after taking a quiz and never see the key or answers.
