Type of delivery of the course

The teaching methodology consists of lectures for acquiring fundamental knowledge to achieve the educational objectives scheduled. The attending Students to teaching activities is optional. All information are available: http://webusers.fis.uniroma3.it/~plastino/EP_-_%282018-2019%29/EP.html

Type of evaluation

The verification of skills learning takes place through an oral test lasting about 1 hour, for verifying the level of effective understanding of the concepts and the students' ability to apply them in real contexts.
