Prerequisites:
The proposed program will also allow students who have not previously matured
Disciplinary knowledge to achieve the training objectives indicated. There are therefore no prerequisites, but we recommend a knowledge of the notions of mathematics present in all high school programs.

Teaching Methods
Evaluation methods Verification of learning:
The evaluation method consists of 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.
