BSGenerator: a Tool to Design Unique Online Examinations using Question Variations

The sudden arrival of the COVID-19 pandemic caused chaos in a multitude of industries and sectors. In many universities around the world, the resulting restrictions forced the closure of campuses, and with face-to-face examinations cancelled, a rapid adaptation of assessment strategies was needed.To adapt to this scenario, we developed a software tool to assist in the design of unique examinations for each student, when using online quizzes. Results from its application to a large cohort of students validate the approach taken, in terms of fairness of assessment, grade distribution, and foul play deterrence.This paper describes the developed approach, its advantages and limitations, and plans for future refinement.
