Methodology
In this course, specific teaching is offered where there will be different formative activities that are described next. The work hours that are specified for each training activity correspond to an average student. Naturally, not all students need the same time to learn concepts and carry out certain activities, so the distribution of time should be understood as guidance. In this subject, we try to promote the active participation of the student as a relevant learning tool.
Direct training activities:
Master classes sessions: classes in which the theory teacher explains the most relevant concepts of each subject. Usually, they are blackboard classes, although in some cases classes are done with computer programs. Students have notes or copy of the transparencies in pdf format in advance uploaded in the virtual campus of the UAB.
Problems sessions: classes in which the problem teacher explains to the students how the standard problems of the subject are solved. The teacher will resolve in detail a list of selected problems and will propose to the students a list of problems that must be delivered as a mandatory task that will be part of the evaluation of the subject.
Discussion classes: discussion of selected readings (scientific articles) in direct relation to the topic of the subject will be evaluated with a presentation in class.
Laboratory practices: Students will perform laboratory practices as a learning tool.
Supervised training activities:
Tutorials: in the hours of attention to the students, the teachers will be available for the consultations of the students.
Autonomous training activities:
Problem-solving and delivery of additional problems: the student must solve the problems of the list given by the teachers. Some selected problems will be required to be delivered and will be evaluated by the professor.
Studyand preparation of exams: Personal work of the student to acquire the theoretical concepts of the subject and the abilities for the resolution of problems.
Works: students will be asked to generate a small report, in certain thematics that complement the contents of the subject. The derived marks will be part of the evaluation.
If the health situation requires a reduced attendance:
-Master sessions will be uploaded in video format, and discussed online in tutorial sessions in the scheduled hours.
-On-site sessions will be used essentially to solve problems, and to the realization of specific tutorials on the theoretical material previously supplied.
-The assistance to laboratory practices will be addapted to follow health considerations.
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
The subject will consider different types of assessment activities.
- Partial exams: Several synthesis tests will be done where the theoretical knowledge of each thematic block will be evaluated. These partial test will be programmed throughout the semester taking profit of the preset schedule for partial test. The total weight of each partials on the final mark will be 70%. If any of the partial exams does not reach the mark of 4 out of 10, it will have to be compensated in a final evaluation.
The relative weight of each partial exam will be decided based on the academic course and contents considered, but in all the cases any partial exam will exceed more than 50% of the final mark.
- Continuous and practical evaluation activities. During the course there will be different activities of continuous evaluation that will have a weight of 30% on the final note. These activities will include laboratory practices, writing reports, monographic works, presentations and delivery of problems.
Recovery. There will be a final exam of recovery where students can be examined from the parts of the suspended partials. In order to be able to get benefit from the recovery exam, the student should have participated in at least a minimum of 2/3 of the evaluation activities of the complete subject. Continuous evaluation activities are intended to evaluate the daily follow-up of the subject and therefore, as in the case of laboratory practices, they can not be recovered.
Depending on health scenario the evaluation will be adapted.
