A package to export test questions into Moodle from python or latex
Project description
moodlexport
This Python module provides code which allows to easily generate families of questions (called categories in Moodle) that can be directly exported from either Python or Latex to Moodle, and use them to create a test. The main motivation behind this module is that :
- it is easier to define mathematical objects in Python than Moodle
- it is more comfortable to type maths in Latex
- generating random problems is simpler in Python and can go way beyond what Moodle proposes
- it is easier to store/manipulate locally a Latex or Python file than doing it on the Moodle interface. It also simplifies collaborating projects.
It can be installed with a pip command : pip install moodlexport
Simple examples from Python:
from moodlexport import Question
question = Question("essay")
question.text("What is the derivative of $f(x) = e^x + 0.5 \Vert x \Vert^2$?")
question.grade(1.5)
question.save("my first question")
Simple examples from Latex
You can produce the same result as above by defining your question directly in a Latex file.
Suppose for isntance that you have a Latex file myquestion.tex
containing the following :
\documentclass{amsart}
\usepackage{latextomoodle}
\begin{document}
\begin{question}[essay]
What is the derivative of $f(x) = e^x + 0.5 \Vert x \Vert^2$?
\grade{1.5}
\end{question}
\end{document}
Then you can convert this myquestion.tex
file directly into a readytoexport.xml
file, by using the following Python commands:
from moodlexport import latextomoodle
latextomoodle('myquestion.tex','my first question')
Note that if you wish to compile the .tex
file without errors, you will need to place the Latex package latextomoodle.sty
in the same folder. This package can be found in the latex folder of this project.
Exporting many questions at once
If you want to export more than one question, you might want to gather them within a category, which will produce a single file containing all those questions. Here is how to proceed:
In Python:
from moodlexport import Question, Category
category = Category("My little catgory name")
question = Question("essay")
question.text("What is the derivative of $f(x) = e^x + 0.5 \Vert x \Vert^2$?")
question.grade(1.5)
question.addto(category)
question = Question("multichoice")
question.text("Is every symmetric matrix invertible?")
question.grade(2.0)
question.answer("Yes", False)
question.answer("No", True)
question.addto(category)
category.save()
In Latex, followed by the python command latextomoodle('file_name.tex')
:
\documentclass{amsart}
\usepackage{latextomoodle}
\begin{document}
\begin{category}[My little catgory name]
\begin{question}[essay]
What is the derivative of $f(x) = e^x + 0.5 \Vert x \Vert^2$?
\grade{1.5}
\end{question}
\begin{question}[multichoice]
Is every symmetric matrix invertible?
\answer[0]{Yes}
\answer[100]{No}
\grade{2.0}
\end{question}
\end{category}
\end{document}
Features of this module so far :
- Creating a question. Supported classes of questions are:
- "essay" : the student answers in a white text box. Options are :
- Possibility for the student to upload a file as an answer as well.
- "multichoice" : the question comes with at least 2 possible answers. Options are :
- Possibility to specify "multiple answers allowed" or "unique answer allowed"
- "essay" : the student answers in a white text box. Options are :
- All the options available in Moodle are available here (defining a grade, information for the grader, feedback, etc)
- Creating a category (family) of questions
- Adding a question to a given category
- Export a category of questions under the format Moodle XML, which can be imported directly into Moodle.
- Supports Unicode éà ê ...
- Supports Latex syntax : correctly supports inline latex with
$e^x$
, and equation with$$ f(x) = \sum_i x_i^2 $$, \begin{equation*}...\end{equation*}, \begin{cases}
etc
Known issues/missing features :
- for multichoice we never check that the sum of the fractions is equal to 100%
- for the latex package, there is issues with
newcommand
andrenewcommand
because for instance the document classamsart
definestext
but it is not the case forarticle
.
