Assessment methods

Students who regularly attend lectures during the final two class sessions will be required to give a 15–20 minute presentation on one of the topics covered in the course (maximum score: 20 points).

At the end of the course, all students must take a written test consisting of 2–3 open-ended questions (maximum score: 12 points).

Students who choose not to give an in-class presentation will instead take a written test on the day of the exam. This test will require them to develop a short essay based on an outline provided by the instructor, to be completed within 90 minutes (maximum score: 20 points).

Students may choose the assessment method that best aligns with their academic background. However, they are expected to engage with the proposed topics with a high level of rigor and appropriateness, considering the interdisciplinary nature of the issues discussed.

Academic dishonesty in any form will not be tolerated. In order to take the exam, students must be registered on Almaesami.

Students with specific learning disorders (SLDs), or with temporary or permanent disabilities, are strongly encouraged to contact the appropriate university office in advance (https://site.unibo.it/studenti-con-disabilita-e-dsa/it ). The office will evaluate individual needs and recommend any necessary accommodations. These recommendations must be submitted no later than 15 days prior to the relevant academic activity for approval by the course instructor, who will assess their appropriateness in light of the course’s learning objectives.
