Adds an matching pair for an matching question.
Adds an matching pair for an matching choice question. The students have to fill in an order for the matching pair. The matching pair is an ASS_AnswerMatching object that will be created and assigned to the array $this->matchingpairs.
- Parameters:
-
string $answertext The answer text string $matchingtext The matching text of the answer text double $points The points for selecting the matching pair (even negative points can be used) integer $order A possible display order of the matching pair public
- See also:
- $matchingpairs
