Turning numeric into single-choice exercises with R/exams
Short tutorial about turning randomized numeric exercises into single-choice exercises using R/exams (http://www.R-exams.org/). Such questions are particularly useful for written multiple-choice exams that can be automatically scanned (see http://www.R-exams.org/intro/written/) but can also be easily employed in learning management systems (like Moodle, Canvas, or OpenOLAT).
The exercises files from the video are available in the useR! 2019 tutorial at http://www.R-exams.org/general/user2019/
The R/exams package ships with two similar exercises with a slightly more advanced solution formatting: http://www.R-exams.org/templates/deriv/ and http://www.R-exams.org/templates/deriv2/
A written tutorial with similar example from economics (computing a price elasticity) is available at http://www.R-exams.org/tutorials/stat...
