Teaching Methodologies

The classes introducing each topic in syllabus contents are supported by PowerPoint presentations. The remaining classes consist in the resolution by the students of exercises concerning these topics. Student’s active participation is encouraged by solving questions on key points of the syllabus. The laboratory activities are carried out by the students according to the Practical Guide available online since the beginning of the semester All the pedagogical materials use in the classes and laboratory is available online on the Moodle e-learning platform.
