The evaluation type default incorrect can only be used in negative feedback and has no automated feedback. A negative feedback rule of this type always reacts to wrong answers and has a predefined priority of 99.
As can be seen here, if no negative feedback rules are applicable to the student’s answer, the student will simply see a red cross with the text “Wrong”. This evaluation type can be used to replace the word “Wrong” with a text of your choice that is more informative to the student, for example: “This is not correct. Try … (insert hint here)”
Example:
Note that this evaluation type does not have automated feedback.
