Teaching methods

Frontal lessons

Assessment methods

Verification of learning consists in an oral exam, for each module, which aims to verify and evaluate the achievement of the learning objectives.
The student evaluations takes into account the correctness of the answers, the  understanding of the principles learned showed by the student. In addition, the level of exposure, also in relation to the previous knowledge necessary for the understanding of the specific exam subject will be considered. The duration of the oral exam is on average 20-30 minutes.

Teaching tools

PC, Projector. PowerPoint; the slides used during lessons will be available on the VIRTUALE platform
