Metodi didattici

The course will be based predominantly on frontal lectures. Students are expected to attend lectures and complete the mandatory readings. A detailed list of readings will be provided during the course: some papers will be discussed in class by the professor, and some others will be assigned to students for their presentation in front of their classmates.

Modalità di verifica e valutazione dell'apprendimento

The course grade will be determined by a presentation by the student (or by a group of students, depending on the numerosity of the class) and a final written exam. The presentation will account for 20% of the final grade, and the final exam will account for the remaining 80%.

The final grade is graduated as follows:
- <18: failed
- 18: sufficient
- 19-23: satisfactory
- 24-26: good
- 27-29: very good
- 30 e lode: excellent
