This repository provides an interactive shiny dashboard for creating and evaluating written multiple-choice exams. The underlying workhorse is R/exams, in particular the so-called NOPS exams which support both single-choice and multiple-choice exercises along with automatic evaluation.
The dashboard provides:
- Import/export of R/exams exercises with type "schoice" or "mchoice"
- Creation of an exam by combining (blocks of) exercises and exporting (randomized) PDF files
- Evaluation scanned exercises
- Management of participants and grades, connecting with other tools at Universität Innsbruck
Rex is developed by Sebastian Bachler and is still work-in-progress.
To try out Rex make sure that you have all the necessary R packages installed, see init.R.
Then start the up in the base directory via shiny::runApp() and authenticate using rex
as both login and password.
