Get Started With R/Exams And Dynamic Data Science Teaching In Moodle

R/Exams is an extension of the popular, open source, scientific bundle, R, which in the past decade has experienced a significant adoption growth courtesy of increasing interest in data science. Today, R shares (with programming language Python) top-ranking status as a tool to aid in the processes of data cleanup, analysis, and visualization.

R/Exams has existed for more than a decade, but only recently did the team realize the present-day potential of R/Exams to help introduce more students to the tool and the data science field at large. The authors also credit Moodle and other LMS with making it easier to leverage R/Exams into data science and R training programs.

The best way to get started with R/Exams is on the official blog. It features real case studies, which double as tutorials on the software’s innovative features. R/Exams lets instructors program printable questions, where everything on the page (from content to layout) is editable through R code. This makes is simple to automate the creation of math test, for example, with equally structured questions but with different quantities for each student to neutralize cheating. For an LMS, a post documents a similar take on dynamic questions for multiple- and single-choice types, developed at the University of Innsbruck, where answers and accompanying graphical aid are procedurally generated.

To create questions compatible with the Moodle Quiz activity, you need the R software with the Sweave and the R/Exams libraries installed. After writing the code for a question, use the exams2moodle() function to create an XML file with all the question’s variations, which can be imported on a Moodle site. If the question includes visualizations or formulas written using the LaTeX syntax, the MathJax Filter type plugin for Moodle is recommended for properly display across web browsers.
