EVERSYS: Efficient exam versioning tool for linear circuits and other problem‐based subjects

Abstract

AbstractExam versioning is a widely used approach to prevent cheating during exams, but it can increase the workload for lecturers in terms of exam preparation and correction. Automated exam versioning can help reduce this workload and minimize errors in correction. This article presents the EVERSYS platform, which is focused on linear circuits but can be applied to other engineering fields. An exam problem is described as a circuit schema, a set of component values, and a set of questions to be answered. The EVERSYS platform allows lecturers to easily create exam versions with high variability, including different schemas, component values, and question sets. The platform is based on the MATLAB/Octave programming language and HTML document descriptions. Creating a multiversion exam is straightforward, involving the adaptation of a set of predefined MATLAB scripts and modification of the HTML format if necessary. A set of example exams is provided as well as the complete platform source code. The platform was tested during a 2021–2022 compulsory course on linear circuits at a Spanish University. The results indicated that the platform significantly reduced the time required for exam preparation and correction, and there was no statistically significant difference in student performance across different exam versions. Students reported high levels of satisfaction with the platform, and almost all agreed that it effectively prevents cheating during exams.
