Base Knowledge
Not applicable.
Teaching Methodologies
In theoretical classes, a theoretical exposition of each subject is made.
In theoretical-practical classes, equipment and tools are identified and a demonstration of their use is made.
In practical classes, practical work is carried out to apply the knowledge transmitted in the theoretical and theoretical-practical component.
