SEMINARS

Seminar about the use and programming in the software MATLAB.

A1. Lectures with big group of students

They are based in the explanation of the theory concepts, exercises and practical problems of the course.

A2. Lectures with practical groups

They are based on the explanation of the practical units in the lab including the execution by the students and resolution of problems in class.

The use of electronic devices in classes and exams is forbidden except that they are required for the right develoment of learning activities and always with the authorization of the lecturer.

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

At the end of the semester, the student has to choose between two methods of evaluation: CONTINUOUS EVALUATION or FINAL EXAM.

CONTINUOUS EVALUATION

This assessment method is organised according to the activities described in the following table.

To pass the subject, the student has to get a mark higher or equal than 5.0 out of 10 in the overall result of the evaluated aspects, as long as he or she has obtained a mark higher or equal than 4.0 in each one of those assessed aspects.

FINAL EXAM EVALUATION

This kind of evaluation is based in only one written exam that evaluates all the aspects of the subject, by assessing the students' acquisition of all the competences and learning outcomes established in the subject. This exam will take place during the Examination period on a date established by the centre. The final exam is weighted in the following way:

- Attendance and participation (S1), Theoretical concepts (S2) and Exercises, problems and study cases (S3): 70%.

- Laboratory and computer practical work (S4): 30%.

In order to pass the subject, the student must have marks higher or equal to 5.0 out of 10 at each part of the final exam.

The students who have already fulfil the requirements of aspect S4 (Laboratory or computer practical work) through the CONTINUOUS EVALUATION, by obtaining a mark higher or equal to 5.0 out of 10 do not have to make this part in the FINAL EXAM evaluation.

Those aspects successfully completed with a mark higher or equal to 5.0 will be considered passing during that academic year.

Using this approach, the following competences will be evaluated: CB10, CB6, CB7, CB8, CB9, CE1, CG10, CG4, CG5, CG6, CG7, CG8, CG9, CT1, CT2, CT3, CT4, CT5, CT6 and CT7.
Obtaining a positive evaluation indicates that the student has reached the following learning results of the module: 13, 14 and 15.
