Currently feedback is shown for every possible answer in a multiple choice question. This is unintuitive, however, this seems to be by design:
"Unlike some other quiz systems, all feedback items are displayed on correction. With other quiz systems, the norm is to display the feedback only for those items which were selected by the user" (https://en.wikiversity.org/wiki/Help:Quiz#Inserting_feedback)
We need to develop a consensus on what, if anything, to do about this.
- Leave as is
- Change feedback so that it behaves like other Quiz systems, i.e. GIFT: https://docs.moodle.org/20/en/GIFT_format#Feedback and only show feedback from selected answers.
- Extend the Quiz format such that conditional feedback is possible, i.e. keep the current type where feedback is always shown, but add other types of feedback that are conditional. If so, this also needs further discussion. There are several options, i.e.
|| always show
||? only show if selected
||- only show if incorrect (false positive or false negative)
||+ only show if correct
Input is also needed on the notation.
