This plugin inherits that behaviour from the standard Moodle question type. So, this is really MDL-43174.

Hi, quick question. When there are more right answers than wrong answers and a student selects everything, he still gets more than 0 points. Could there be an option to automatically give 0 points when a student selects everything?

Thanks Philip! I think, this is a bug and should be fixed.

I think I take the opposite view. This question type has a simple scoring system: +1/n for each right choice selected, -1/n for each wrong choice. If you want the score for selecting everything to be 0, then make sure you have at least as many distractors as right choices.

(I am now imaging a question with choices like "This is a wrong option. Don't select it. Are you event paying attention?" Is that as pedagogically invalid as it at first seems?)

Hello we are upgrading a site from 3.5 to 3.9 and the display of your question type is not correct anymore. We tested in different 3.9 sites without any theming but the result is the same. The tickboxes and answer options are not outlined. The text for the answer is one line lower than the tickbox. Please advise! I could not sent a screenshot here but please let me know when you need any. Thanks Peter Jonker

There were changes to core multiple-choice question type in Moodle 3.9, with ongoing bug fixes in 3.9.1 and 3.9.2 to sort out some issues.

I guess that in time we will need to make simiilar changes to this plugin, to match what is done in the core question types, but I will wait for the core code to finalise before i do anything.

Hi Tim, thanks for your prompt reply. I will watch for updates.

Hi, are there any news on the update of the plugin. I would like to use the combined question plugin but the tickboxes and the answer options continue to not be aligned. The answers go to the next line.

I am afraid the answer is "When I get time". That might be this weeek, but it might not.

I had to fix the alignment issue for our Moodle 3.9. Since the renderer looked to be based off of multichoice questions, I found that updating the following two classes in styles.css to match multichoice worked.
.que.oumultiresponse .answer div.r1 {
/* padding: 0.3em 0 0.3em 25px;
text-indent: -25px; */
display: flex;
margin: 0.25rem 0;
align-items: flex-start;
}
.que.oumultiresponse .answer div.r1 input {
/* margin: 0 5px;
padding: 0;
width: 15px; */
margin: 0.3rem 0.5rem;
width: 14px;
}

Yes. that is the right general approach. However, the styles in Moodle core for this keep changing. We did a fix like this in our theme for Modoel 3.9.2, and then it broke again for 3.9.3.

Hi there,
We are testing this very valuable plugin but are facing difficulties in grading. It is said that the student scores 1/n for each correct choice, and loses 1/n for each incorrect choice and here is what we get for a question with 5 options (3 correct and 2 incorrect)

1 correct 0 incorrect -> 33%
2 correct 0 incorrect -> 66%
3 correct 0 incorrect -> 100%
1 correct 1 incorrect -> 33%
2 correct 1 incorrect -> 66%
3 correct 1 incorrect -> 66%
1 correct 2 incorrect -> 33%
2 correct 2 incorrect -> 33%
3 correct 2 incorrect -> 33%
0 correct 1 incorrect -> 0%
0 correct 2 incorrect -> 0%

Any help?
Thanks in advance

I guess the simple description is too simple! Let me try a fuller description, using your sepecific example 5 options (3 correct and 2 incorrect).

If the student has selected 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 has selected too few choices, then add more 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 = 33%; or 2 right == 2 right 1 wrong = 67%

If the student has selected too many choices, then remove correct choices, to make the number exactly 3. So, 2 right and 2 wrong == 1 right and 2 wrong = 33%.

(The last point is the only sense in which the student "loses 1/n for each incorrect choice".)

I hope that makes sense. We think this scoring scheme is fair: rewarding students for what they know, and without generating false incetives that help students game the system.

I agree with Tim that the scoring mechanism for this plugin is much fairer than using the built-in Multiple Choice question type, which is a) harder to use with multiple response type options, and b) very easy to create warped data where students are over penalised for choosing too many options.

Thanks Tim for your prompt and very clear answer. It makes sense now and I totally agree with your arguments.
This being said, IMHO, the plugin description should mention this so that users are aware of it
Cheers
