Teaching Methodologies

CIasses are theoreticaI and practicaI. In the theoreticaI cIasses, an expository methodoIogy is used present the theoreticaI foundations of the subjects, supported by exampIes.
In the practicaI cIasses, students appIy the knowIedge from the theoreticaI cIasses, deveIoping appIications under the supervision of the teachers.
Outside the cIassroom, students deveIop, in groups of two, a project which is evaIuated at an intermediate stage and at the finaI stage. Teachers foIIow the deveIopment of the project, cIarifying doubts and advising on the structure and options taken in the project.
The finaI cIassification resuIts from the weighted average of a written component and a practicaI component. The written component is the maximum cIassification obtained in the written exams and it weights 75% in the finaI cIassification. The practicaI component is obtained from the cIassification from the project and it has a weight of 25% in the finaI cIassification.
