Methodologies
Methodologies   ::  
  Description
Problem solving, classroom exercises Problems will be solved at the end of each theoretical topic. The resolution of these will consist of the approach, development and interpretation of results.
Tutorship of group Practical and theoretical problems will be posed for the students and the teacher to solve together.
Laboratory practicals Practical work will be carried out that will serve to contrast the theoretical results with the real ones.
Lecture Theoretical classes where the theoretical bases of the subject will be explained, reasoned and deduced.
