Teaching methods

The course includes lectures, group work and practical exercises on the topics included in the programme.

Assessment methods

The final examination verifies the acquisition of the expected knowledge and skills through an oral test. The oral test covers the topics dealt with in the course and is aimed at verifying the student's understanding of the theoretical and experimental aspects of the methodologies covered by the course. The final grade is expressed in thirtieths.

Teaching tools

 blackboard, power point presentation and other materials for  the execises
