Teaching methods

Frontal lectures in classroom

Assessment methods

The assessment will be performed through a written test and an oral presentation.

The written exam will be composed of both open and closed questions with around 12 questions. The time is 90 minutes. For the oral presentation students have the possibility to focus on a specific topic. Each student prepares a presentation for the final exam discussing the selected topic with detail. During the final exam we will discuss also on the written test about possible mistakes.

Teaching tools

Use of slides during the lessons.
