Online two-stage exams as an examination method in statistics courses

Collaborative examination scenarios provide additional learning experience during an exam by providing additional feedback. Two-stage exams, in particular, combine the individual performance of students with group discussions and allow students to work out a correct solution using several attempts, if they are uncertain. This paper presents the transition from individual, paper-based exams to online two-stage exams in two statistics courses during the Covid- 19 pandemic and investigates the examination results. The results show that students benefit from this method in multiple ways and that learning takes place during the examination.
