Methodology
In this semester the teaching will be presented in a virtual way.
The work methodology will combine the face-to-face classes, the realisation of works in the laboratory, the realisation of works from recommended readings and the autonomous work of the student. It will make use of the virtual platform and the presentation of works related with the thematic blocks will be required.
During the course, we will carry out the following activities:
- Theory sessions (directed), where the teacher will provide information on the knowledge of the subject and on strategies to acquire, expand and organise this knowledge. The active participation of the students will be encouraged during these sessions, for example posing discussions in those points that admit diverse technological solutions.
- Problems sessions (directed), where the students will have to actively take part to consolidate the knowledge acquired resolving, presenting and debating related problems. Problems are distinguished from the exercises, which can be considered as trivial problems. The problems often will admit several solutions and will be able to originate debate between the students.
- Laboratory practical sessions (supervised and autonomous), where small projects will be posed to be analysed and developed by the students in group. The sessions will be previously prepared, documented and programmed by the teacher, and the students will have to prepare them before assisting, reviewing the related theoretical knowledge and the basic technical aspects developmental. The practical sessions must serve to the students to attain the skills of the subject and contribute to attain some competitions such as the one of autonomous work.
- Preparation of the portfolio of the subject (autonomous), in a virtual way through a wiki, collaborative work web tool. The students will have to work autonomously in teams in the research and the preparation of the corresponding material of the evidences of his theory andproblems learning, and in the study of this material. The evidences comprise extensions of the different subjects exposed to the sessions of theory and collaborative resolution of problems. The teacher will do the follow-up of the work of the different teams, will provide feedback to the teams depending of the task done and of the doubts that pose or of the errors that manifest. The preparation of the portfolio has to serve to the students to contribute to attain the competitions of the subject. The teaching methodology and the evaluation go tightly tied to the wiki-based virtual portfolio system, that is the cohesive element of the different teaching activities during the course, and that allow a system of continued and formative evaluation, incorporated to the process of education/learning. The wiki will help the students to develop a constant work that will bring them to attain the knowledge proposed, and the skills and the competitions associated to the theory and problems parts.

Assessment
Assessment systems
- Written tests: Partial and final written tests
- Delivery of reports or problems: Brief reports on specific subjects
- Work in the laboratory and corresponding memories: it will assess the previous preparation of the laboratory session, the capacity to realise it in an efficient form and the quality of the analyses reflected in the memory.
- Presentations and participation in the problems and cases seminars: it will assess the previous preparation of the questions/exercises/cases assigned for the session
The final mark for the course, that includes the assessment of the acquisition of knowledge and skills, is calculated in the following way:
- 25%, from the mark of the work done in delivery of reports or problems. The minimum required in this part is 5 out of 10.
- If the student passes the validation of knowledge tests and the minimum of the work in the portfolio is not reached, he/she will be able to recover this part before the closing date for marks.
- 40%, from the mark of the written tests. The minimum required in this part is 5 out of 10.
- To carry out the validation of the knowledge, there will be two partial tests during the year (a partial test to assess Part I of the course and a partial test to assess Part II of the course) and a final exam (to assess both parts).
- If the student gets more than 4 in any of the two partial tests, he/she will not be assessed again from this part in the final exam (the mark of this part will be the one from the partial exam). The final mark will be the average of the marks obtained in both parts. To calculate the average, the student must obtain more than a mark of 4 in each of the parts (either in the partials or in the final tests). In case that a student gets more than 4 in both partial tests, but the average is lower than 5, he/she will have to take the final exam of the part with a mark lower than 5 (in case both parts are lower than 5, the student will be able to decide if he wants to take the final exam of both parts or only 1 of them).
- 10%, from the mark of the work in the presentations and participation in the problems and cases seminars. No minimum is required for this part.
- 25%, from the mark of the laboratory. The minimum required in this part is 5 out of 10.
- If the student does not get the minimum mark of the laboratory sessions, he/she will be able to recover this part before the closing date for marks.
A minimum final grade of 5 is required to pass the course.
When a student does not pass any of the parts that require a minimum mark, the average will be calculated with the marks obtained. If this average is equal to or less than 4.9, the final grade will be this average, whereas if it is greater than 4.9 the final grade will be 4.9 (S).
The assessment mechanisms used in the subject are described in more detail below.
Programming of assessment activities
The dates of continuous assessment and delivery of works will be published the first day of the course on the virtual campus (and/or wiki page of the course) and may be subject to possible changes due to adaptation to possible incidents. These changes will always be reported on the virtual campus (and/or wiki page of the course) since it is understood that this is the usual platform for the exchange of information between teachers and students.
The following assessment activities are planned:
- Portfolio: weekly
- Classroom activities: in the problems classes
- Laboratory: 6 sessions during the course, in general every other week
- Theory partial exams of parts I and II of the subject: around weeks 10 and 15
- Theory final exam
Retaking process
Students may take the retaking process if they have taken a set of activities that represent at least two-thirds of the total grade of the course.
Retaking mechanisms will focus on activities 1) Portfolio, 2) Validation of Knowledge, 3) Laboratory sessions. In the event that a student has not passed any, or all of these parts, before the date of the final exam, she/he can retake this part by means of a written test (cases 2 and 3), making a second delivery of the laboratory work/report (case 3) or finishing the wiki Portfolio before that date (case 1). In case 1, if the student retakes the Portfolio part, he or she/he will get a pass or fail. If the student passes, she/he will have a maximum mark of 5. If she/he fails, she/he will get the mark previously obtained in this part.
Review of the exam procedure
For each assessment activity, a place, date and time of revision will be indicated in which the student will be able to review the activity with the teacher. In this context, claims may be made about the activity mark, which will be assessed by the teacher responsible for the subject. Unless otherwise noted, if the student does not attend this revision, this activity will not be reviewed later.
Special grades
When a student has not done any work in laboratory, has not taken any of the partial or final theory written tests, and has a mark lower than 5 in the work in the presentations and participation in the problems and cases seminars, it will be considered that there are not enough assessment evidences, and the final mark will be "not assessable." The rest of students who have not passed the course will get a "Suspens" (fail) grade, with the mark obtained in the subject. Those students qualified with "Suspens" due to not having reached the minimum mark in any of the assessment tests, will have the mark got in the assessment exam that has not reached the minimum required (always taking the minimum mark in the case that the minimum in several testsisnot obtained).
Honor grade (Matrícula d'Honor, MH): Granting an honor grade qualification is a decision of the faculty responsible for the subject. The regulations of the UAB indicate that MH can only be awarded to students who have obtained a final grade of 9.00 or more. It can be granted up to 5% of MH of the total number of students enrolled.
Student irregularities, copy and plagiarism
Without prejudice to other disciplinary measures deemed appropriate, and in accordance with current academic regulations, any irregularities committed by the student that could lead to a variation of the grade of an assessment act will be graded with a zero. Therefore, copying or allowing to copy a laboratory work/report or any other assessment activity will involve failing with a zero, and if it is necessary to pass it to pass the course, the whole course will be failed. The assessment activities qualified in this way and by this procedure will not be retaken, and therefore the course will be failed directly without the opportunity to retake it in the same academic year.
Assessment of repeater students
Repeater students will be able to validate the theory part of the subject. The way to calculate the final mark will be the same as mentioned above, taking the note from the portfolio, classroom activities and exam(s) of the part(s) of the theory to validate.
Repeater students will also be able to validate the laboratory sessions separately. The way to calculate the final mark will be the same as mentioned above, taking the mark from the laboratory session(s) to validate.
