Question types ::: qtype_oumultiresponse

The main difference from the standard Moodle multiple choice question type is in the way that grading works. When creating the question, the teacher just indicates which choices are correct. If there are n correct choices, then the student scores 1/n for each correct choice. If they select too many choices, then incorrect choices outweigh correct ones.
There are working examples in eAssessment with Moodle on our OpenLearn site.
The documentation is in How to create questions in Moodle on that site.
And example of how the grading works, using an example with 5 options, 3 correct and 2 incorrect:
- If the student selects the right number of choices (3) then their score is the fraction that are correct (0/3, 1/3, 2/3 or 3/3).
- If the student selects too few choices, add incorrect choices to make the number exactly 3, then score as above. For example, 1 right and 1 wrong is the same as 1 right and 2 wrong = 1/3; or 2 right => 2 right 1 wrong = 2/3.
- If the student selects too many choices, then remove correct choices to make the number exactly 3. So, 2 right and 2 wrong => 1 right and 2 wrong = 1/3.
This logic is extended to compute a fair grade when interactive with mulitple tries behaviour is used.
