Moodle in English: looking for new maintainer(s) for drag-and-drop matching and ordering

looking for new maintainer(s) for drag-and-drop matching and ordering

by Adriane Boyd - Sunday, 7 August 2011, 1:32 AM

Hi everyone,

I've been very short on time recently and I wanted to see if I could find someone who was interested in taking over as maintainer of two of my question types: drag-and-drop matching and drag-and-drop ordering. According to Tim's recent survey, they're used by quite a few moodlers and I'm sure your efforts would be very much appreciated by the moodle community. They're both based on the core matching question and are fairly similar underneath the hood, so it would probably make sense for both of them to have the same maintainer(s).

The functionality has stayed very stable over the last four years and I've only had to fix a handful of bugs in that time. Most of the work is in updating them for newer releases of moodle and answering questions from users. If you're interested, send me a message and I can help you get up to speed. The main outstanding task at this point is to update them for 2.1.

I don't know how useful it would be but I took the core match question code for 2.1 and renamed everything so it would work with ddmatch (i.e. import and export) but just show up with the functionality of the match question.That version of the code seems to work OK as a stopgap.

I sat down tonight to work out how to port the drag drop bit but then decided the Matt Damon movie "The Adjustment Bureau" was a better way to spend Saturday night.

I can send you the code if you are interested.

Please do.

A propo the adjustment bureau I've actually been planning to push for adjusting the core question(s) to support a dd layer, rather than duplicating the core in plugins and then having to waste a lot of energy on essentially the same import/export backup/restore.

That sounds like a good idea. I have made extensive use of the ddmatch question type and I really like it. However there are some quirks in it that mean it can freeze sometimes. I was about to look at the code in the ddwtos question type (a very nice question type) to see how that does it.

Re: looking for new maintainer(s) for drag-and-drop matching and ordering

by Itamar Tzadok - Sunday, 7 August 2011, 6:33 AM

I've implemented dd ordering, matching, filling the gap, scramble etc. on top of a CLOZE question type. The approach was fairly simple. The lists are entered as bulleted lists, then the html is parsed and regenerated in a yui-dragdrop-friendly way, and yui does the rest. Not much to it. So, what I'm proposing to try is adding an option to each relevant core question and some code where the question html is generated for display and the app js file. Then if the user tick the dd option of the question, the question will be rendered accordingly and js will be required and the question will display on the quiz page in its dd skin.

Here are a couple of illustration. In this implementation each item has a unique random key which is generated and assigned to it when the question is prepared for display. Whenever an item is dropped, the keys are written into the resp input field. In the ordering the key are written in the order of the elements. In the classification question, where the order is not important, the keys are written in alphabetical order.

This looks just wonderful! Kudos, Itamar!

There is one (stupid) question I keep asking myself, though. Will this still be compatible with my old Drag-and-Drop ordering questions when I upload my courses to Moode 2.1+? I am asking because I am dealing with quite a large number of questions of that type which I cannot afford to loose at this point.

Martin

Re: looking for new maintainer(s) for drag-and-drop matching and ordering

by Tim Hunt - Sunday, 7 August 2011, 6:19 PM

I'm not sure about that. The problem is that with the plain match quetsion type, the drag elements need to be strictly plain text. With ddmatch it should be possible to have some HTML in there, at least <b>, <i>, <sup> and <sub>.

Anyway, with the new question engine, you should not have to copy and paste much, you should be able to do a lot with subclassing.

For example, look at how little code there is in https://github.com/timhunt/moodle-qtype_ddwtos because it derives from https://github.com/timhunt/moodle-qtype_gapselect.

Hi Itamar,

Anthony has assigned the tracker categories to you and I made you the owner of the two outstanding tracker issues. From the discussion here, it sounds like 2.1 versions will be ready soon, which is great! (Thanks, Artem!)

Let me know when you'd like to take over the contrib database entries. Anthony said he can just change the owner to you. (It would be nice if you could maintain a note in the description that I originally added the entry.)

Hi Itamar,

I hadn't see Artem much in the quiz forum before this discussion and you volunteered directly, so I thought it made more sense, at least initially, to transfer things to you, since I knew for sure that you were familiar with everything.

At this point, it can be your call: if you would like to transfer everything to Artem and Artem would be willing to take over, it is all fine with me, and he can also get access to the contrib entries, which haven't been modified yet.

Hello,

As this tread is the main one for Moodle 2.1 versions of ddmatch and order maybe it would be usefull for users of these questions to report here that I have added restoration of 1.9 backups and XML import/export to ddmatch for Moodle 2.1 and posted my version here.

I will also post a comment in CONTRIB-3057 so that Andreev is aware of that.

I just restored about 30 ddmatch questions from 1.9 to 2.1 and it seems to have worked fine. It did throw up some messages during the restore that looked like some debug prints that had not been commented out, but that could be entirely unrelated to the restore process. Many thanks jean-michel

I wouldn't wory too much, Moodle will not install with foreign keys turned on with a database engine that actually takes any notice of foreign keys . Though that foreign key checking capability is something I had not seen previously and I will investigate.

Heh, I missed something, but I hope I'm not too late.

I've done reimplementing drag&drop matching question based on core matching question with some changes:

drag&drop matching question for Moodle 1.9 don't forbid image inserting. But Moodle 2.0 version doesn't have WYSIWYG editor for answer fields (and appropriate db field 'answerformat'). I added ability to use WYSIWYG editor for answer fields.
correctansweris don't displayed when question state correct;
correct answer is displayed as table: not <question text> - <answer text>. When question and/or answer text contain HTML correct answer looked ugly.

Git: https://github.com/andreev-artem/moodle_question_type_ddmatch/tree/WIP_MDL_21

At this moment drag&drop matching question not well tested (especially existing attempts upgrading) so do NOT use it on production servers.

thanks alot for maintaining those important questiontypes!

I tested them a bit here are my results:

Both order and ddmatch work fine in IE8 which is from 2009 and in so far a bit outdated now. I also have no problems in FireFox 5.

I have in IE9 the Problem, that I cant drag anything at all. The dragable fields just doesnt react on the mouse.

In Firefox 6 the dragable fields are dragable, but once you chose one item it is not possible to drop it anyway even "esc" does'nt help.

Since those questiontypes are very useful, I hope thos problems might be solved soon.

Did you ever thought to maintain Adrianne Boyds incredible "image target" question I really loved in moodle 1.9?

Thanks for kind words but porting ddmatch and order to 2.1 was actually done and is currently maintained by Artem Andreev. My implementation as illustrated above is a javascript layer over the cloze question and requires a designated builder to generate the question code. I'm still planning to implement it as a question type for 2.1 and higher with YUI 3 along side Artem's question types, since my approach allows for flexible design of the question layout in the spirit of the cloze question.

Great work on those question types porting. Here's my feedback:

Importing "Drag-and-drop" questions from Moodle 1.9.x to Moodle 2.1 doesn't seem to work - all i get is a single bar to drag, although I had more dragable objects.

I tested creating quizes in Moodle 2.1.x and all works ok (both "Drag and Drop" and "Ordering").

Are you going to work further on these question types? I really would like to be able to import 1.9 quizes in 2.1 with both types, but specially "Drag and Drop").
