Learning activities and methodology
The educational methodology includes: 1) Lectures covering the main topics of the course. In order to facilitate the learning process the students will receive support material and information to let them complete and focus on the degree's relevant topics or the interesting topics for them. 2) Resolution of problems, related to the knowledge that must be acquired and above all related to the specific competences the student must develop. 3) Resolution of applied exercises that will allow the student to consolidate the knowledge and contrast the results with the reality. This will develop the capacity of self-evaluation and the students will acquire skills and develop technical creativity. 4) Reports elaboration and presentation. 5) Sharing of answers and group corrections, which should be used to consolidate knowledge and develop the ability to analyze and transmit the relevant information to solve problems. Besides, sharing of answers will favor the exchange of constructive critical opinions both amongst the students and between the students and the instructor.
