Methodologies
Methodologies Description
Introductory activities Initial session to introduce the subject, where students will be informed about the content that is intended to cover, the teaching methodology, for large and small groups, and the assessment criteria.
Guest lecture / keynote speech The theoretical content will be discussed at the keynote sessions, through multimedia presentations given by the teaching staff. The presentations, covering the basic content and additional material, will be available for the students at the Moodle platform.
Seminar The seminars will address the analysis and resolution of some of the previously proposed exercises. In order to make the most of these sessions, it is very important that students work the exercises prior to their resolution in the classroom. The proposed exercises, and the data tables, will be available in advance at the Moodle platform.
Laboratory practice The students will perform seven lab practices related to the fundamental contents of the subject. The lab sessions will last two hours each. The scripts for the practices include the experimental procedure and some related questions. At the end of the sessions the students must submit an individual written report collecting the lab work, observations, results, and answers to proposed questions.
Supervised projects The main target of these sessions is the follow-up of the comprehension of the subject by the students. For this purpose, 8 sessions of 1 hour of tutoring in small groups are scheduled. Students must prepare each tutorial in advance, studying the corresponding contents and solving the exercises of the previous bulletins that will be available at the Moodle platform. In the tutorials the proposed exercises will be solved and discussed on the board, preferably by the students. Brief short tests by surprise and/or through the Moodle platform can be carried out during these tutorials and they will contribute to the final assessment.
Objective test The degree of concepts assimilation and problem solving skills of the students will be assessed by mean a written exam.

Description
In addition to the follow-up work in group tutoring sessions, there will be individual tutoring in the schedule set by the teachers.

In the specific case of part-time Students with exemption of attendance, seminars and supervised work will be led through individual and/or group tutoring schedule to be agreed with the teachers.

Assessment
Methodologies Competencies Description Qualification
Laboratory practice A26 A30 A31 B1 B2 B3 B4 C1 The score of the practices represents 20% of the overall score. The submitted report, the attitude and the work done in the lab will be assessed. To pass the subject is necessary to obtain a minimum score of 4 in this part.

20
Supervised projects A26 B1 B2 B3 B4 The score of the supervised work represents 20% of the overall score. The individual work of the student with the previous questionnaires will be assessed as well as the active participation of the student in the tutorials, the attendance and the qualifications of the short tests in class and via Moodle.

20
Objective test A26 B1 B2 B3 B4 C1 The objective test consist of a number of practical or theoretical-practical exercises, similar to those made in seminars and tutorials. To pass the subject is necessary to obtain a minimum score of 4 in this part.

Assessment comments

To pass the subject it is necessary to obtain a higher or equal to 5 points overall rating (out of 10) in one of the two calls (January and July). A score below 4 on the objective test or laboratory practices implies failing the subject.

The completion of the labs is mandatory to pass the subject. In the first and second opportunities, students who failed the lab practices could undergo a specific test related to the lab practices. The qualification of this specific test will replace the mark obtained in lab practices.

The attendance to the supervised work is mandatory to pass the subject. Students who attend less than 50% of those tutorials will obtain a qualification lower than 50% in this section for both assessment opportunities in January and July, regardless of their qualification obtained in the short tests during tutorials or via Moodle. In the second opportunity of July, in order to obtain the global qualification, the qualification obtained during the course in this section will be maintained.

In the specific case of students with recognition of part-time dedication and academic assistance waiver, the mark of the tutored work will be replaced by that obtained in the personal tutorials, counting as 20% of the overall grade in the first and the second opportunities. In case of exceptional, and appropriately justified circumstances, the teacher may fully or partly exempt any student to perform continuous evaluation process. In such case the sutudents will undergo a specifically designed test, in any of the opportunities scheduled.

"Not attended" assessment mark will be applied when the students attend fewer than 25% of planned academic activities (supervised work and practices), and do not assist to the objective test.
