Lectures supported by visual aids will be used to convey critical information on the topics relating to the contents of the course.
Assessment methods and criteria
The outcomes of learning will be verified through an oral examination.
Questions on the topics relating to the course will be used to test the knowledge and the understanding of the student in the scientific discipline, in order to apply such knowledge and understanding in occupational contexts.
