Teaching Methods

The course includes frontal teaching, divided into lessons of 2 hours depending on the academic calendar. The frontal teaching consists of theoretical lessons and practical application with exercises. During the lessons, the main topics of the teaching are explained with examples on the blackboard or on a computer.

Evaluation methods

Verification of learning:

The evaluation method consists of the oral examination and the topics under examination will reflect those discussed during the lessons and present in the program. Specifically, both the topics on the basic principles and the application of these topics to the analysis techniques applied during this course of study will be eaminated. The exam mode and the evaluation method will be indicated by the teacher at the beginning of the course. The evaluation will be based on the knowledge of the topics covered by the exam questions and the students? logical-argumentative skills. For the purpose of the evaluation, the quality of the oral presentation will also be taken into consideration with particular reference to the competence in the use of the specialized lexicon.

Contacts/More Information

Students are expected to receive Tuesday morning from 09.00 to 11.00.
It is possible to choose another time by appointment agreed by e-mail or by telephone.
