Moodle plugins directory: Multinumerical

Hi Mike,
Okay, there is apparently an upgrade path I didn't think of. To solve your problem, you can safely delete line 50 of the multinuerical/db/upgrade.php file. Then the upgrade process should be able to finish correctly.

When will this question type be compatible with 2.7? I only see it up to 2.6. Is 2.6 version work on 2.7?

Thank you,

Hello, just uploaded new version, supporting Moodle 2.3-2.7.

I am still getting the error with the new file.

Field "questionid" does not exist in table "question_multinumerical"

Thank you,

I've just updated the plugin. No changes but a couple bug fixes and now officially supporting up to Moodle 2.9.

Hi Nicolas,

I've just come across this question type and am interested in using it to set multi-part calculation questions where any calculation errors on the part of the user are carried forward and taken into account in their next answer.

It seems to work where the answers are whole numbers, but falls down where irrational numbers are concerned. I'd like to be able to set a tolerance on correct answers but haven't found a way to do it. I was thinking that Boolean operators might work but they don't seem to be recognised. Is that right? Is there any other way to do this that you can think of?

Hi James,

I'm not sure to understand precisely what you're trying to achieve, but intervals for correct responses can be defined, i.e.:

X + Y = [57;62]

There's no way to use boolean operators. If you feel like PM'ing me some more details, I can try to think of something.

This is amazing--merci beaucoup! I use it to have students assess their own lab work in chemistry.

Thanks Andrew, it's always motivating to get feedback. Let me know if you think of possible improvements.

Hi,
Any updates do Moodle 3.4?

Ricardo

Hi Ricardo,

I didn't test extensively, but this should work on 3.4.

I just published an article about using this plugin to assess lab work: https://teachchemistry.org/periodical/issues/may-2018/use-moodle-to-score-lab-calculations-instantly

Thanks again for your work on this software--it's transformed my science classroom. After using the plugin extensively with my classes, I have a few suggestions to make it even better:

1) Create an option to automatically mark zeros or blank parameters incorrect. Right now it is possible for a student to score points by leaving input boxes blank (as many operations involving 0 will return 0).

2) Allow the display of custom text by the input box, instead of the parameter name.

3) More options for grading (e.g. some constraints may be worth more than others)

4) Allow the user to set a tolerance for each parameter (right now I am accomplishing this by using the range function, but it is awkward)

Thanks again!
Andrew

Hi Andrew,

Thanks for your feedback!

1) What about if zero is a correct answer? Can you describe when it is possible to score points when it shouldn't?

2-4) Good idea! Thanks for the suggestions, I'll try to implement this.


Nicolas

Thanks a lot for the plugin! I can't live without it. However, there are a few things I find really necessary:
1) Allow for a constraint of the type x != val.
2) Give optional feedback for erroneous answers. For example: the constraint says: x=8; but the student answers x=9, and I know the typical mistake why somebody would say 9; I would like to say something specific when that answer is given.
3) I support Andrew's point 4), it is quite cumbersome to use a range.
4) I would like to give Ok|Error as specific feedback, but print the exact answers when right answer is ticked. Currently when the constraint is of the type '=' the right answer appears even when I set 'calculations only'... that gives the answers away .
Please let me know if I can help in the process.

Kind regards.

Hello Veronica,

Thanks for your feedback. The best would be this to all be reported in the same place, which is GitHub (see link "Bug tracker" at the top of this page). I have just created a few entries related to Andrew's suggestions. Feel free to add in on those, or to create new issues yourself for the points you mention.

This helps to document the process, but there is no guarantee I will have time to work on this in the near future, so if you have the ability or know someone willing to code this (most should be quite simple but time consuming to fully test etc.), I'd be happy to review any submitted code changes and integrate them in the plugin.

Kind regards,
Nicolas
