Re: Developing Moodle resources/sites with Org Mode

[Devin Prater]

I don't like Moodle's interface at all. Just a web page edit field to 
type into. So, I have everything in Markdown on Github, and I link to 
that with Moodle URL type lessons. I'd love more support for Moodle in 
other software, since a folder of files is tons easier than tons of web 
pages. I'm not a programmer, but I can manage to use Emacs and the 
command line.

Thanks!  I have been thinking about getting something like this going

for a while.  WebWork sort of does some of this, but I like Moodle/STACK

so much better.

When I came across Org Mode it was quite a revelation.  Like you, I wish

I had done something some time ago: I should have learned about Org Mode

years ago.  It is very close to being exactly what I want: a rich

environment for creating and previewing randomizable test questions that

can be used to automatically generate paper tests or STACK questions for

Moodle.

I've started a GitHub site: https://github.com/edoolittle/org-moodle 



I've posted the final exam to the site.  Lots of work needs to be done

on it still: in particular the full solutions need to be added, and the

randomization needs to be implemented.  Currently versions are

varied/randomized manually by adjusting the Parameters section at the

beginning of each question.  Finally, I have just copy/pasted from one

version to another but that needs to be redesigned.  There should be

only one copy of the test in the master file, and versions could be

created by exporting Org to Org (so that the parameters chosen for the

version are stored in the secondary Org file).

Thank you for the assessment.  I moved very quickly into this space, but

I was fortunate to be able to have 3 full days free over the holidays to

get up to speed.  Lots of fumbling around but I have been pleased with

how it all turned out.

Going forward, I am most confused about whether to transform Org to XML

and then to Moodle XML, or whether to export from Org directly to Moodle

XML.  In the short term the first will be easier for me, I think.

Yes, that would be nice to have.

Yes, I have gone down a similar path. I prefer to ask STACK/Moodle to do
as little as possible. One additional reason for this is that the list
of "disallowed" Maxima functions grows with each release of STACK.

I have attached a different type of work-around. It uses Maxima's `save'
command and the :prologue and :epilogue header arguments.

I have toyed with putting in session support. It does not seem too
difficult, but I have needed a reason to do it. Good is the enemy of
better.

Oh, I encountered this problem a while ago when I submitted a patch to
the STACK documentation. IIRC, there is some undocumented numbering,
etc. etc.

I believe that `draw' support is a project goal, but I think that
jsxgraph has attracted much more attention.

Yes, that's right. If you have a small example, please feel free to share.

Nice idea.  You might find it useful to look into the source code for
the R/Exams package for R (https://www.r-exams.org/).  The format there
is RMarkdown as opposed to org mode, but I imagine a lot of the same
ideas might apply.  I'm pretty sure that Moodle was the original
platform that the developers were using, but they now support most of
the big platforms.

I've used R/Exams a good bit by now, and I always generate at least 16
random versions of every quiz or exam.  The process is pretty automatic.

I'm a Moodle noob and rusty on the tools, but this is interesting to
think about.

You may not need any additional library for the XML export bit. The
builtin Org HTML exporter does XHTML export by default, and XHTML is an
XML, so one could just apply XSLT to that. There may be advantages to
using a library like om-to-xml (cleaner, more semantic XML; access to
more properties than what gets exported). But it looks like Moodle only
uses XML to wrap the glossary entries and their properties; any markup
inside the glossary definitions appears to be in HTML (with the html
tags entity-escaped), not defined by the Moodle glossary XML format. So
if you're going to have some markup in the definitions, you may be
better off leaving the (X)HTML part to Org instead of reimplementing it
in XSLT.

Another option might be to dispense with XSLT entirely and just write
elisp code to map the entries of an Org glossary and generate Moodle XML
from that.

How would you format the glossary on the Org side? Would you use Org
entries (** term) or Org description lists (- term :: definition)?

On the Moodle side, do you want keywords and attachments?

Yours,
Christian

Re: Developing Moodle resources/sites with Org Mode

[Edward Doolittle]

Thank you for your thoughts.
I have used org-mode to do all my STACK question authoring for a few
years now [1]. I do all the writing in emacs and then copy/paste into the
STACK textareas, test, repeat. It is not elegant, but it is easier than
working in a web-browser. It would be really nice to be able to create
the entire question in emacs, because defining graders in STACK is
pretty tedious.
I had a look at the message you refer to.  It is a good summary, and in line 
with what I thought was straightforwardly do-able. I haven't uploaded any of my 
problems to STACK yet but that's how I imagined it going: cutting and pasting 
like you say.  In the long run I'd like to be able to export to Moodle XML, 
then automatically upload the XML to the Moodle site.

I have been making use of tex1 and texput in Maxima to generate LaTeX.  It is 
alarming to me that they may not  be supported by default in Moodle/STACK.  I 
decided to do most of the LaTeX generation in Maxima instead of writing the 
LaTeX and filling in the values of variables because of situations like the 
following:  If Maxima has a0:-3 and I write LaTeX \(x-{@a@}\) I will get \(x- 
-3\) which is exactly what I asked for but unconventional.  If I define Maxima 
output0:tex1(x-a0), Maxima will do the algebra and LaTeX \({@output0@}\) will 
be \(x+3\) as we would normally expect.  Lots of little things like that made 
me prefer assembling expressions in Maxima and exporting them whole hog instead 
of one bit at a time.

Some more thought will have to be given to how to create the grading trees.  
I'm sure it's documented somewhere but I'll probably just create a question 
with some complicated grading trees and export it from Moodle to see what the 
XML looks like.  I think I won't go there for now because the Maxima fragments 
on the grading side run in the same session as the Maxima initialization on the 
question side in STACK, but that is rather awkward to fake in Org until there 
is a session capability in the Maxima blocks, I think.  So it might be possible 
to write the grading trees in Org but would be difficult to test them.

There is no export from Moodle to XML but there are external packages that will 
do it ... with what quality, I don't know.  But once the Org file is in "Org 
XML" it should be relatively straightforward to transform it to the XML 
required by Moodle using XSLT or whatever.  Lots of details, but that's my big 
picture strategy.  I'd like eventually to export directly from Org to Moodle 
XML but that's currently beyond my skill set.
I agree that we need ob-maxima.el to properly handle sessions. Note that
you can use Maxima to create graphs, too.
I posted my kludge to work around the lack of sessions to 
https://github.com/edoolittle/org-moodle.  It's pretty ugly but works for now.

Again, the work to sessionize Maxima is probably straightforward but lots of 
details that are currently beyond my skill set.  I am not proficient at Emacs 
Lisp. For now I'm concentrating on the low-hanging fruit that I can do quickly.

I have avoided for now using the Maxima "plot" command.  Actually, it's 
"plot2d" in Maxima/Org and "plot" in Maxima/STACK. Note they are two slightly 
different things, which means that one must always be conscious of the context 
and not use any of the nicer "plot2d" features when writing questions that will 
eventually find their way into Moodle/STACK.

Also  "plot" is just too restrictive in some cases.  I can graph two curves 
(parametric curves even) and put dots at their intersection points but I can't 
figure out how to label those dots.  Which is A and which is B?  So even though 
I've used it in the past, I think I'd rather put my energy into figuring out 
how to generate diagrams with JSXgraph which is modern, sophisticated, and 
beautiful compared to plot.  A difficulty is how to get the {#maxima-variable#} 
out of the maxima results and into the JSXgraph block.  I /think/​ that's just 
a minor issue with noweb.

One thing that I am not sure I understand about your thoughts: do you
envision a Moodle emulator based on org-mode, or do you just want to be
able to write Moodle questions or glossaries with org-mode?
I think an emulator is a bridge too far for now.  What I want to do is run 
Maxima blocks to get a paper version of the exam with an answer key (for 
graders) and complete solutions (as an "exam wrapper" to return to the students 
with their graded exams so they can learn from the correct answers).  Both 
questions and answers will have to be generated (the variable parts anyway) by 
Maxima because I want the capability to generate multiple different paper 
versions of any question/exam, perhaps even one version of the exam per 
student.  Then for versatility I want the questions to be in a form that can at 
least be cut-and-pasted into Moodle, so I can use last year's exam questions as 
this year's problem set questions.  With some tweaks, I hope to eventually 
automate the procedure of get

Maybe the ~moodle~ LaTeX package, which helps for the generation of

[Fraga, Eric]

This sounds very good!  I am particularly impressed with being able to
use maxima to create questions that have a random element.  I wish I'd
had what you have done back at the start of the pandemic when I had to
create quizzes for my moduless.

In answer to your actual question: no, I do not believe you are off the

others would benefit greatly if they have to interact with moodle and
its xml formats etc.

Developing Moodle resources/sites with Org Mode

[Edward Doolittle]

Hello everyone,

I'm new to Org Mode but I really enjoy working with it.

I have begun thinking about how I might use Org mode to improve the experience 
of developing resources for the open source Moodle LMS or even developing 
entire Moodle sites.  Currently I develop Moodle content for mathematics 
courses using their online editors which are quite basic.  I would like to be 
able to edit in Emacs and preview my work before uploading to Moodle.  Below 
are four potential use cases I see:

1) ​Development of HTML pages to upload to Moodle.  This can already be done 
with Org export to HTML/MathJax.  One nice bonus: it is possible to integrate 
diagrams and graphs into a Moodle HTML page using JSXgraph.  JSXgraph is just 
Javascript so is already supported in Org Mode.  A couple of small 
modifications to the js block will create a jsxgraph source block in Org mode 
which will enable immediate preview of static graphs in PNG format and preview 
of dynamic graphs by exporting to HTML.  Decent LaTeX versions of pages with 
static graphs could easily be exported.  I am very close to setting this up.  I 
have JSGgraphs producing PNG files on the command line with node.js and the 
jsxgraph.js library.  A few lines of elisp to wrap jsxgraph blocks in the 
appropriate incantations is all that is needed.

2) Development of Moodle glossaries. Glossaries can be uploaded to a Moodle 
site using an appropriate XML file.  Glossaries could be developed in Org mode, 
including JSXgraph diagrams and graphs, PNG images, and so on, and then Org 
mode converted to XML and the XML transformed to Moodle Glossary XML using 
XSLT.  (I don't really know those tools at all, so I don't know if that would 
be a good way to go about the process; exporting directly to Moodle Glossary 
was my first thought, but it is not a general export that is necessary or 
appropriate, rather an export of a specifically designed Org file.  XSLT seems 
old fashioned but there are tools around, and there is a project for exporting 
Org mode to XML.)

3) Development of Moodle quiz question databases.  I know less about the format 
but it is documented at some level on the Moodle help site.  From what I 
understand the same process for exporting a glossary would work for a question 
database (Org -> Org XML -> XSLT -> Moodle XML), but question database are 
rather more complicated than glossaries, with numerous different types of 
questions.  Still, it is mostly straightforward for simple question types.  
However, I am particularly interested in the STACK question type, which is a 
mixture of HTML, LaTeX (MathJax), and Maxima code, which can be used (for 
example) to randomize a question.  Maxima source code blocks already work well 
in Org mode.  Some work might need to be done connecting them to LaTeX in which 
{@maxima-variable@} can be used to refer to variables in a Maxima code block.  
Similarly JSXgraph blocks can refer to Maxima variables through the 
{#maxima-variable#} syntax.  This is somewhat complicated by there being 
multiple Maxima code blocks in one question (there is a main one that executes 
immediately and others that seem to execute when the student has provided 
answers).  An issue I foresee is that a Maxima session might be required to 
correctly represent state but currently there is no Maxima session available in 
Org mode.

I have already written a statistics exam with Org Mode and Maxima.  I can 
generate as many different versions of a question (and associated answer key 
and solution set) as I wish with almost no additional effort.  In order to 
facilitate import into Moodle STACK, I have had to restrict my access to Maxima 
variables using accessors also written in Maxima ... I import the Maxima block 
into the accessor with noweb.  I end up re-running the same chunk of Maxima 
code over and over, once for each variable access, because there is no Maxima 
session.  It is kind of stupid but I tossed it together in three days.  I 
suppose I could store the results of a Maxima run in a table and just do table 
lookups but I've got the spare compute cycles to run Maxima over and over until 
I sort this all out.  I think Maxima session is the right way to go but I'm 
inexperienced with all this and would appreciate guidance.

4) Development of whole sites: Sites are uploaded to a Moodle server as .tgz of 
XML files with directories of resources (PDF files, PNG files, possibly also 
control files for external applications like Zoom).  I see this as quite a 
challenge but definitely manageable for simple sites, adding features as users 
call for them.

What do people think?  Am I off the mark?  Are there better ways to do this?  
Maybe even setting up my own personal Moodle server and connecting Emacs to it 
as an external editor would work reasonably well and save me some of the pain?  
But it would be nice to export some things to formats other than Moodle: a 
glossary in LaTeX might be nice, for example, and quiz questions in
