What is this repository for?

This Software extends the analysis possibilities of ILIAS an e-assessment system. It provides the following features:

  • computation of grades (variable schema)
  • computation of Item-total correlation and difficulty for questions
  • generate some diagrams

Limitations

  • only supports single choice questions

How do I get set up?

You need R and the following R-libs:

  • psych
  • string
  • R.utils
  • XML
  • rCharts
  • digest
  • plyr

rCharts must be installed according to the installation instructions in the GitHub repository. The other libraries should be available as packages and can be installed directly.

How do I use it?

  • In ILIAS, go the export tab of your test and download the CSV as well as the XML file and place them into the input directory
  • have a look at the main.R, it shows the usage of the different functions
  • run the main.R file
  • the input files are backed up into the output directory
  • all diagrams and other output is placed inside the output directory
