Quiz Responses [4]: You can choose to allow students to view their answers, any automatic feedback generated by the quiz for correct or incorrect answers, and which questions they got wrong. Quizzes default to this option, so if you do not want students to see their quiz responses, deselect the checkbox.
As part of this option, you can restrict students view of the quiz results to Only Once After Each Attempt [5]. Students will only be able to view the results immediately after they have completed the quiz—results include both their responses and the correct answers.
Notes:
- Students will still see their quiz score upon submitting a quiz when this option is enabled. Because of this, this option may not be appropriate for quizzes that require manual grading, such as essay questions, where students may need to access the quiz results multiple times to see an updated quiz score.
- When a quiz is saved with the Only Once After Each Attempt option, you can use the Moderate Quiz feature to give students additional views to their quiz results.
Correct Answers [6]: You can allow students to see correct quiz answers after completing the quiz. This setting enables a green Correct tab on every correct answer for the entire quiz. Quizzes default to this option, so if you do not want students to see the correct answers, deselect the checkbox.
As a part of this option, you can also control when and for how long students can see the correct answers by setting dates (and specific times, if desired) in the Show and Hide fields.
- To show answers immediately after quiz is submitted, leave the Show and Hide fields blank.
- To create a date range to display the answers, set a start date in the Show field and an ending date in the Hide field.
- To always show answers after a specific date, set a date in the Show field.
- To hide answers after a specific date, set a date in the Hide field.
Note: If the Only Once After Each Attempt option is selected, it will override any show or hide dates or times. If you want to show or hide correct answers on any specific date or time, the Only Once option should not be selected.
