Hi Cristina,
Yes, you can. With multiple answer questions, you can set the grade for each option in a question to positive or negative points. See: https://docs.moodle.org/28/en/Multiple_Choice_question_type#Multiple-answer_questions
I hope this helps!
Yes, it helps, thank you!
However, it doesn't solve my problem completely, because I cannot set the grade for each option as an absolute value or in correlation to the other options.
Let's say I have a question with four choices, among which 2 are correct. What I want to do is to subtract -1 from the total grade if one or both of the wrong answers are checked, not -0.5 if one wrong answer is checked and -1 if both are checked.
Also, if a question has 3 correct choices out of 4, I would like the value of the grade to be 2 if all the correct choices are checked (and the wrong one is not checked), and 1 if the question is partially answered (meaning 1 or 2 correct choices checked).
There are almost infinitely many ways people might want to grade multiple response questions.
If the way that the standard Moodle question types does it, which is pretty flexible, is not good enough, and if the extra question types available in the plugins database (https://moodle.org/plugins/view/qtype_oumultiresponse or https://moodle.org/plugins/view/qtype_multichoiceset) don't meet your needs, then the only option is to make another new question types, with your own particular scoring rules.
Thank you! This really helped. I am planning to use OU multiple response for now.
It looks like I need to make a new question type. I am a middle level (Java ) programmer, have had some experience with PHP a long time ago, but I'm an absolute beginner to Moodle development.
Is there any step-by-step kind of tutorial to developing custom question types in Moodle, that could get me started?
Many thanks,
Cristina
In your case I think the better approach is to clone the multiple choice question type and build the new question type based on that clone (rename all the references to multiplechoice inside the clone to your new plugin name ...)
