Learning activities and methodology
| Title | Hours | ECTS | Learning outcomes |
|---|---|---|---|
| Laboratory sessions | 8 | 0.32 | CM19, KM35, SM30 |
| Magistral lectures | 30 | 1.2 | KM35, SM30 |
| Problem set solving and lab reports | 30 | 1.2 | CM19, KM35, SM30 |
| Study of theoretical foudations | 68 | 2.72 | CM19, KM35, SM30 |
| Classroom practical sessions | 10 | 0.4 | CM19, KM35, SM30 |
Formation will be based on magistral lectures complemented with practical classroom and laboratory sessions. There will be autonomous activities including problem solving and the critical reading of texts.
For this course, the use of Artificial Intelligence (AI) technologies is permitted exclusively for bibliographic or information searches, text spellchecking, or translations.
Assessment
Continuous assessment activities
| Title | Weight | Hours | ECTS | Learning outcomes |
|---|---|---|---|---|
| Problem sets and independent work | 20% | 0 | 0 | CM19, SM30 |
| Laboratory sessions | 25% | 0 | 0 | CM19, SM30 |
| Synthesis test | 55% | 4 | 0.16 | KM35, SM30 |
The completion of the lab sessions is mandatory, and students must pass the lab sessions separately
Continuous evaluation
In order to pass the course a minimum grade of 4 in the synthesis test is required. This can be obtained:
a) When the mean of the synthesis partial tests reaches a 4, and none of the partial tests has a qualification below 2.
b) When the synthesis retake test reaches the minimum of 4.
The student must have sat in the two partial synthesis tests and passed the lab sessions in order to be allowed to retake the synthesis test.
Single evaluation
The students who have signed up for the single evaluation modality must take a final test that will consist of a written exam of the entire theoretical syllabus and problems of the course, and an oral test treating aspects of the theory part that are not have been covered in the written test. These tests will be carried out on the day that the continuous evaluation students take the second partial exam. The written test will determine the mark that will enter the "Synthesis Test", while the oral test will determine the mark that will enter "Problem sets and independent works".
If the grade of the synthesis test does not reach 4, or the final grade does not reach 5, the student has another opportunity to pass the subject through the written recovery exam that will be held on the date set by the coordination of the degree. In this test, 75% of the mark corresponding to the subject can be recovered; in other words, the grade obtained will replace that of the written and oral tests of the single evaluation. The Lab Sessions part is not recoverable.
"Matrícula d'honor" and grade improvement
"Matrícula d'honor" will be awarded with preferent attention to the results of the synthesis partial tests (continued ev.) / written+oral (single ev.) over the second chance synthesis test. Sitting on the second chance synthesis test to obtain a better grade is possible, but in case the grade of that test is lower than the grade of the mean of the partial tests / written + oral, the final synthesis grade will be the mean between the average of the partial test and the grade of the second chance synthesis test.
Synthesis tests may be substituted by additional problem sets and independent work if authorities determine that on site exams are not permitted.
Academic Misconduct
Any irregularity committed in a graded activity (academic misconduct, plagiarism, or improper use of Artificial Intelligence, unless such use is expressly authorized in the Guia Docent) that may lead to a significant alteration of the grade will result in that activity being graded with a 0.
If the Guia Docent stipulates that obtaining a minimum grade in that graded activity is an essential requirement to pass the course, or if multiple irregularities occur in graded activities within the same course, the final grade for the course will be 0.
In addition, disciplinary proceedings may be initiated against any student who commits any of these irregularities.
