Open Book exams are written exams that are conducted without supervision. Aids are explicitly admitted, i.e. students have access to all available aids during the exam, e.g. course materials, literature, internet access. Collaboration with other staff, people is not allowed.
The Corona Regulations (in german) of Bielefeld University define Open Book examinations as examinations in the sense of the Examination rules, Subject-specific regulations and module descriptions (§ 2.5). Therefore, the processing times specified there apply (max. 4 hours). An extension of the processing or examination time is possible if the examination is taken online or mediated by electronic communication formats (§ 2.6). In deviation from regulations in Examination rules, electronic verification of the student's own authorship of the work can generally take place for these examinations/supervisory work and not only in justified individual cases.
Potentials and challenges of open book examinations:
Examinations with open questions and approved aids (open book examinations) are a form of examination with specific potentials and challenges.
More detailed information on the didactic implementation of open book exams can be found in this handout (in german).
The didactic considerations for an online oral examination are similar to those for an analogue examination. Some special features of the digital version are listed here:
Technical breakdowns when conducting a digital oral examination
The legal regulations give you leeway in deciding at what point an examination can no longer be conducted due to technical breakdowns or at what point there is reasonable suspicion of fraud. Think about how you want to deal with technical breakdowns. At what point is an examination no longer feasible for you or at what point are you able to form a grade despite the technically necessary abortion? Are your students also allowed to break off the examination if they have the impression that technical breakdowns are having an unfavourable influence on the history? For orientation, the following can apply:
