Lectures in large group: They will consist of master classes of the program content for the whole group. The contents will be developed and discussed. In some subjects audiovisual sessions are used for a better understanding of the contents. Problems and exercises proposed by the professor will be solved. This methodology and activities will allow students to acquire the indicated competences.

Small group classes: Focused on project-based learning, classes will be held in the laboratory or in the classroom, where the student will receive a script with the objectives of each practice or project and the procedure to follow for its development. The student will have to take note of the necessary data
to carry out the development or the corresponding calculations and to be able to make a correct report. In addition, exercises will be solved, expositions and other practical activities will be carried out.

Collective and individual tutorials: Where the supervision of directed works, comments to individual works and clarification of doubts will take place.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

Written exam on the dates officially indicated in the student's guide. This objective test will consist of answering short questions in which the most important aspects of the subject are addressed, as well as problem solving (CC3; CC10) (38; 39; 40; 41; 42; 43; 44). In addition, there will be intermediate thematic tests that the student will have to pass with a grade higher than 5 out of 10.

Laboratory practices: Delivery of Reports (CC3) (38; 39; 40). Delivery of the proposed problems (CC3; CC10) (38; 39; 40; 41; 42; 43; 44).
Attendance and active participation in class (CC3; CC10). In order to obtain the 5% of qualification the student must attend at least 80% of classes and participate actively in the proposed activities and questionnaires.

In extraordinary convocation it will be guaranteed that the student can pass the course, and in its case, obtain the maximum grade, by means of the accomplishment of an evaluation test.

In the mixed scenario, the teaching modality (format) is not chosen by the teacher, but is determined by the center.and will be: "face-to-face as far as the socio-sanitary situation allows".

All teaching activities -including evaluation- will be face-to-face as far as the socio-sanitary situation allows it.

1.  TEACHING METHODOLOGY AND TRAINING ACTIVITIES

(*) The Center may establish a different percentage of attendance depending on the number of students and capacity of the classroom/laboratory in accordance with health measures.

(**) The Center may establish rotating attendance depending on the number of students and capacity of the classroom/laboratory in accordance with health measures (class in the timetable and classroom/laboratory assigned to part of the group and retransmission by videoconference to the rest, with periodic rotation of students, as determined by the Center).
