◆ $correctness

int question_display_options::$correctness = self::VISIBLE

inherited

Should the student have what they got right and wrong clearly indicated.

This includes the green/red hilighting of the bits of their response, whether the one-line summary of the current state of the question says correct/incorrect or just answered. {

See also: question_display_options\HIDDEN} or {; question_display_options\VISIBLE}

◆ $editquestionparams

array question_display_options::$editquestionparams = array()

inherited

If not empty, then a link to edit the question will be included in the info box for the question.

If used, this array must contain an element courseid or cmid.

It shoudl also contain a parameter returnurl => moodle_url giving a sensible URL to go back to when the editing form is submitted or cancelled.

This field is now badly named. The place it included is was changed (for the better) but the name was left unchanged for backwards compatibility.

◆ $feedback

int question_display_options::$feedback = self::VISIBLE

inherited

Should the specific feedback be visible.

Specific feedback is typically the part of the feedback that changes based on the answer that the student gave. For example the feedback shown if a particular choice has been chosen in a multi-choice question. It also includes the combined feedback that a lost of question types have (e.g. feedback for any correct/incorrect response.)

This is typically feedback shown to all students after the question is finished, irrespective of which answer they gave.

{

◆ $history

int question_display_options::$history = self::HIDDEN

inherited

◆ $questionidentifier

string question_display_options::$questionidentifier = null

The bitmask patterns use in the review option settings.

In the quiz settings, the review... (e.g. reviewmarks) values are bit patterns that allow what is visible to be change at different times. These constants define which bit is for which time.

bit used to indicate 'during the attempt'.

◆ MAX_DP

int const question_display_options::MAX_DP = 7

inherited

#-
