Methodologies

Methodologies

	Description
Introductory activities	Introduction to the subject, explaining the objectives, the syllabus, the planning, the operation of the practices and the groups, as well as the evaluation and the bibliography.
Lecture	The teacher presents the course syllabus. The student can intervene by raising questions to the teacher.
Laboratory practicals	The sessions are guided by the laboratory teacher and the students work in groups.
Problem solving, exercises in the classroom	The teacher carries out exercises on the theoretical concepts of the lectures.
Personal attention	The teachers of the subject have set a schedule for paying attention to the students. It is recommended to make an appointment by email.

Personalized attention

Description

The teachers of the subject have fixed a schedule for students to attend to and resolve doubts. It is recommended to make an appointment by email.

Due to the health emergency, attention to the student can be provided through online meetings, at previously arranged times by email, or through other virtual tools.

Assessment

Mixed tests

EL2

There are two partial assessment tests. The first test will correspond to topics 1, 2 and 3; while the second will evaluate topics 4 and 5. Each of the tests will consist of a test-type part and some short answer questions (T1 and T2) - which evaluates the acquisition of the theoretical concepts of class and practical laboratory-; and a second problem-solving part (P1 and P2).

QF (final grade) = 0,5 *(0,7 T1 + 0,3 P1) + 0,5 *(0,7 T2 + 0,3 P2)

Others

Other comments and second exam session

There are two partial assessment. The first test will correspond to topics 1, 2 and 3; while the second will evaluate topics 4 and 5. Each of the tests will consist of a test-type part and some short answer questions (T1 and T2) - which evaluates the acquisition of the theoretical concepts of class and practical laboratory-; and a second problem-solving part (P1 and P2).

The student's final grade is determined according to the expression:

QF = 0.5 (0.7 T1 + 0.3 P1) + 0.5 (0.7 T2 + 0.3 P2)

To pass the subject you must obtain a minimum of 5 in the final qualification (QF); as long as the grade in one of the two tests is not lower than 4.

In the second call, students will be evaluated with the parts (in 1st conv.) that have a grade lower than 3.5 or NP.

There are limitations regarding the use or possession of communication and data transmission devices during the tests and they will be mandatory for students to comply with. The teachers of the subject will accept, if appropriate, calculators in the tests of numerical solution of the problems. The exams will be held face-to-face.

Due to a health emergency, in the event of confinement or restrictions on mobility, assessment activities, including exams, would take place online on the scheduled dates. You can consult the updated information in the Moodle area of each subject.

The assessment activities must be planned so that they can be carried out in a mixed mode or online in case of confinement.
