We are using Multiple Choice questions with Multiple Answers. We will tell the student how many answers they need to pick (say three of eight), but there is no way to stop them from picking more than three.
Is there a way to limit the number of answers they can pick in this type of question? Is there a different question type that we should be using that will work better for us?
The problem we have now run into is this:
A student gets part marks for correct answers, and there is no penalty for incorrect answers. So in a questions with 3 correct answers and 5 incorrect answers (a total of 8 answers), they will get .33 of a mark for each correct answer, and no marks for incorrect answers. But if they check ALL 8 answers, they get full marks (1 out of 1), because they pick the correct ones, and there is no penalty for the incorrect.
Is there a way to limit the number of answers they pick to the number of answers with 'fraction' > 0 ??
