1. A Data Mining Approach for Detecting Collusion in Unproctored Online Exams

Author

Langerbein, Janine, Massing, Till, Klenke, Jens, Striewe, Michael, Goedicke, Michael, and Hanck, Christoph

Abstract

Due to the precautionary measures during the COVID-19 pandemic many universities offered unproctored take-home exams. We propose methods to detect potential collusion between students and apply our approach on event log data from take-home exams during the pandemic. We find groups of students with suspiciously similar exams. In addition, we compare our findings to a proctored comparison group. By this, we establish a rule of thumb for evaluating which cases are "outstandingly similar", i.e., suspicious cases. [For the complete proceedings, see ED630829.]

Abstract

We use learning data of an e-assessment platform for an introductory mathematical statistics course to predict the probability of passing the final exam for each student. Subsequently, we send warning emails to students with a low predicted probability to pass the exam. We detect a positive but imprecisely estimated effect of this treatment, suggesting the effectiveness of such interventions only when administered more intensively., Comment: arXiv admin note: text overlap with arXiv:1906.09864
