Please allow me to draw your attention to this conversation http://moodle.org/mod/forum/discuss.php?d=55792
Once you have seen this post you'd appreciate that the following lines are an excerpt from moodle help file for gift format
Feedback:
Feedback can be included for each answer by
following the answer with a number sign (# also known as a hash mark)
and the feedback.
What's the answer to this multiple-choice question?{
~wrong answer#feedback comment on the wrong answer
~another wrong answer#feedback comment on this wrong answer
=right answer#Very good!}
Who's buried in Grant's tomb?{
=no one#excellent answer!
=nobody#excellent answer!}
Grant is buried in Grant's tomb.{FALSE#No one is buried in Grant's tomb.}
For Multiple Choice questions, feedback is displayed only for the answer the student selected. For short answer, feedback is shown only when students input the corresponding correct answer. For true-false questions, the imported feedback is saved so that it will display if the student chose the wrong answer. So, in the last example above, the student would see the feedback only if they selected TRUE as their answer.
The red line above about the feedback needs to be changed because as shown by me and also in the example file attached, feedback for wrong answers can also be given
short answers making screen has only right answers
provision and feedback provision.....so if you want to give a feedback
on wrong answer, put an asterisk (*) in the answer field......and VOILA
remember,
just the asterisk. Nothing else. if you put any other character, then
this will not work because computer actually will interpret this
wildcard as the right answer too and give the feedback associated with
it but sinc the grade will be zero, your student wont get any marks.
Remember:
you cannot do negative marking in this type and ANYTHING other than you
right answer will be treated as option 4 due to the wildcard and given
that feedback and zero marks.
example:
Who's buried in Grant's tomb?{=%100%none#good =%100%nobody#good =%0%*#that was wrong}
i have tried this out successfully so might as well add this point in help file for 1.7
