It’s coming round to that time of year where we have to create the assessment material for courses with an October start date. In many cases, we reuse question forms from previous presentations but change the specific details. If a question is suitably defined, then large parts of this process could be automated.
In the OU, automated question / answer option randomisation is used to provide iCMAs (interactive computer marked assessments) via the student VLE using OpenMark. As well as purely text based questions, questions can include tables or images as part of the question.
One way of supporting such question types is to manually create a set of answer options, perhaps with linked media assets, and then allow randomisation of them.
Another way is to define the question in a generative way so that the correct and incorrect answers are automatically generated.(This seems to be one of those use cases for why ‘everyone should learn to code’;-)
Pinching screenshots from an (old?) OpenMark tutorial, we can see how a dynamically generated question might be defined. For example, create a set of variables:
and then generate a templated question, and student feedback generator, around them:
Packages also exist for creating generative questions/answers more generally. For example, the R
exams package allows you to define question/answer templates in Rmd and then generate questions and solutions in a variety of output document formats.
You can also write templates that include the creation of graphical assets such as charts:
Via my feeds over the weekend, I noticed that this package now also supports the creation of more general diagrams created from a TikZ diagram template. For example, logic diagrams:
(You can see more
exam templates here: www.r-exams.org/templates.)
As I’m still on a “we can do everything in Jupyter” kick, one of the things I’ve explored is various IPython/notebook magics that support diagram creation. At the moment, these are just generic magics that allow you to write TikZ diagrams, for example, that make use of various TikZ packages:
One the to do list is to create some example magics that template different question types.
I’m not sure if OpenCreate is following a similar model? (I seem to have lost access permissions again…)
FWIW, I’ve also started looking at my show’n’tell notebooks again, trying to get them working in Azure notebooks. (OU staff should be able to log in to
OUCU@open.ac.uk credentials.) For the moment, I’m depositing them at https://notebooks.azure.com/OUsefulInfo/libraries/gettingstarted, although some tidying may happen at some point. There are also several more basic demo notebooks I need to put together (e.g. on creating charts and using interactive widgets, digital humanities demos, R demos and (if they work!) polyglot R and python notebook demos, etc.). To use the notebooks interactively, log in and clone the library into your own user space.
