Teaching methods
Frontal lectures, practise exercises on the PC, discussion of scientific papers given by the lecturer
Assessment methods and criteria
At the end of the course each student will receive a written exam to prepare at home, and that will be discussed in detail orally.
With respect to the Dublin’s descriptors, it will be evaluated:
• knowledge and comprehension of the topics discussed in the classroom, considering also the use of text books
• the capacity to apply the acquired knowledge to case studies, where of critical importance will be the capacity to collect data, to interpret them, and to communicate them in a clear and critical way
