Guided activities:
Lectures: The teacher will explain the topics through (i) the
support of notes on screen that will be available to the student in advance
("virtual campus") and (ii) small exercises or complementary
explanations on the class board.
Problem seminars: The teacher will perform, or in some cases,
the students themselves, example problems.
Laboratory sessions: Before completing each practical
session, the student will have to prepare it and deliver at the beginning of
the session the corresponding report (in English). At the end of the internship
session, the student will deliver another report (in English) during the
session.
Supervised activities:
Tutorials: Outside normal class, the student will be able to
require the explanations of the professors of theory, problems or practices for
any doubt. The use of this didactic resource is recommended to the student.
Autonomous activities:
Study: An independent study of each subject of the subject by
the student is necessary.
Resolution of class problems: It is highly recommended that
the student try to do the exercises in advance.
Preparation of the sessions of Laboratory: As mentioned, the
student must prepare a report prior to the performance of the practices.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.
Assessment
Continous Assessment Activities
| Title | Weighting | Hours | ECTS | Learning Outcomes |
|---|---|---|---|---|
| 1st partial exam | 35% | 4 | 0.16 | 2, 4, 7, 8, 9, 11, 13, 17, 19, 24, 26, 28, 29 |
| 2nd partial exam | 35 | 4 | 0.16 | 7, 8, 10, 11, 13, 17, 18, 19, 24, 26, 28 |
| Laboratory sessions for each topic | 30% | 10 | 0.4 | 1, 3, 4, 5, 6, 12, 14, 15, 16, 20, 21, 22, 23, 25, 27, 30, 31, 32 |
CONTINUOUS EVALUATION: The subject will be evaluated compulsorily through two partials, the practices and guided problems according to the following percentages:
.- 1st Partial Exam written: 35% of the GRADE
.- 2nd Partial Exam written: 35% of the GRADE
.- Practices of each subject: 30% of the NOTE
All three must be approved, with a minimum of 5. In case of having a grade lower than 5 in any of the two partials, you can recover the partial (s) suspended in a final exam.
.- Total final written exam: 70% of the GRADE
UNIQUE EVALUATION: Students who have opted for single assessment will have to take a final test consisting of an examination of all the theoretical syllabus and problems of the subject. This test will be carried out on the day on which the students of the continuous evaluation do the exam of the second partial. The student's grade for this exam will be 70% of the grade of the subject.
If the final grade of the exam does not reach 5, the student has another opportunity to pass the subject through the recovery exam that will be held on the date set by the coordination of the degree.
The practical part is not recoverable. Practical sessions are compulsory and students entered for single assessment must also attend and submit their assignments like other continuous assessment students.
