OU multiple response

Question types ::: qtype_oumultiresponse
Maintained by Tim at Lone Pine Koala SanctuaryTim Hunt, Phil Butcher, at the OU (Perry building)Mahmoud Kassaei
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.

    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

    Hi ...
    at our moodle-Installation we have installed "Multiple-Choice (OU)". A collegue realized that the questions are not shown correctly in the moodle-App. Do you know anything about this problem?
    Any hints or chances to solve this problem?

    Best regards,
    Birgit from Germany (Rhineland-Palatinate)

    Hi there,
    It's a pity the alignment bug mentioned by Peter Jonker on Mon, 17 Aug 2020 has still not been fixed. Any hope for a fix at some date?

    Will be fixed when I get time.

    Hi again,
    Using Moodle 3.11 (Build: 20210517) and OU multiple response 2020121800 the following change in styles.css does the trick (i.e. remove the flex-wrap: wrap; line):

    .que.oumultiresponse .answer div.r0,
    .que.oumultiresponse .answer div.r1 {
    display: flex;
    /* flex-wrap: wrap;*/
    align-items: baseline;
    }

    Similar to Jospeh I have corrected the problem by adding some simple CSS - I think it is doing the same as Joseph, except mine changes the text-ident slightly as well:

    /* Stop OU multiple responses question answers wrapping onto next line */
    .que.oumultiresponse .answer div.r0, .que.oumultiresponse .answer div.r1 {
    display: flex;
    flex-wrap: inherit;
    align-items: baseline;
    text-indent: 0px !Important;
    }

    @Dave,
    I can't see any difference with your added text-indent: 0px !Important; Maybe this depends on your Moodle version or theme?
  • Wed, Jul 7, 2021, 12:14 AM
    @Joseph - I am using the Moove theme, If my memory is correct the options were appearing overlapping the check boxes (e.g. with a negative indent), so the text-indent: 0px !Important; was added to nudge the options to the right and stop them overlapping. As you say this is probably all theme dependant, but hopefully any users having problems, will be able to apply either your or my code and one or the other should work.

    Hi, Is a version for Offline Quiz (https://moodle.org/plugins/mod_offlinequiz ) under development ?
    Thank you

    I don't understand the question. Why would this plugin need to do anything special to support mod_offlinequiz?
  • Tue, Aug 10, 2021, 7:59 AM
    To Tim Hunt : Thank you for your answer. I would like to configure questions type "OU multiple response" in an offline quiz in order to apply the scale of the plugin "OU multiple response" in this offline quiz
