Methodologies Description
Guest lecture / keynote speech In the lecture classes the professor will develop the fundamental contents of the program of the subject. To make a good use of these sessions, the student will have to prepare previously the fundamental appearances of the topic to treat, employing the educational material (diagram that reflects the contents of each topic), which will be provided to the student through the Moodle platform. The student also will must read the chapter regarding to the topic to treat in the recommended bibliography
Problem solving Classes in small groups conceived like a group of activities in which the student must participate on a direct way. They are devoted to the resolution of the bulletins of problems, which previously will have been provided to the student through the Moodle platform, and that the students will have to realise of autonomous form for discussion in these classes. Besides, in these sessions any doubts on any appearance related with the lecture sessions will be resolved.
Seminar Initial activity, before beginning the laboratory sessions, which consists on 1 session of 2 hours. In this session, the students will be exposed to the educational methodology that will be employed in the practices of laboratory.
Laboratory practice 6 laboratory sessions of 3 hours of length, in which the student will carry out the application of the theoretical concepts studied in the classroom.
Each practice owns a script and a prelaboratory exercise which will be provided to the student (through Moodle) previously to the practice sessions. The realisation of the prelaboratory exercises before starting the laboratory practice is mandatory. The scripts will have questions that the students will have to answer and deliver once finished the practices.
During laboratory sessions, and on a simultaneous way to the realisation of the experiments, the student will have to elaborate a fascicle of laboratory that collect the calculations and the experimental procedures. The professor will review the notebook of each student in each laboratory session.
Short answer questions Exams about the topics of the subject will be carried out employing short answer questions . These exams will be realised employing the Moodle platform.
Supervised projects Siupervised learning process in small groups (3-4 students) with the aim of helping students to work independently and encouraging students to become responsible for their own learning.
The proposed activities will be related with problem solving sessions. The students will work together to solve the tasks assigned by the teacher, with the aim of optimising their learning experience and that of other members of group. The activities will be discussed in a tutelage session.

Mixed objective/subjective test Two written exams will be carried out in each one of the two official announcements of January/July. One of them will evaluate the learning of the student by means of questions of theory and applied theory and the other one will consist on the resolution of problems.

Personalized attention
Laboratory practice
Problem solving
Supervised projects
The classes of problem solving and laboratory practice are conceived like activities in small groups in which the student participates directly. In this way both methodologies let personalised attention to the students allowing a better follow-up and orientation.

Regarding the supervised projects, for each group of students a tutelage session will be programmed for discussion of the activities and resolution of doubts. Therefore, the teacher will be able to analyse if the process of learning of the student is suitable.

Besides, along the term, the students will be able to do use of the schedule of tutelage sessions for asking queries or doubts about the subject.

Students with official recognition of part-time dedication and academic assistance waiver regime will be attended in a tutorships regime (by appointment). The realization of laboratory practices and assistance to problem solving sessions will be provided within the flexibility to allow coordinating schedules and material and human resources.

Assessment comments
To pass the subject two basic requirements are needed:
1.- The realization of laboratory practice is mandatory to pass the subject.

2.-Reach a minimum qualification in the laboratory practice and in each mixed test. This minimum qualification will cannot be lower than 5 (over 10). Note that the subject will not be approved (even when the overall sum exceeds 5) if one of these particular scores do not reach 5. In this case, the subject is failed and the final qualification will be 4.5.

In the first and second opportunity, the students who carried out the laboratory practice but the obtained qualification was lower than 5, will have the opportunity to, in addition to the mixed test, perform a specific test related to the laboratory practice. The score of this test will replaced the grade obtained in practice for the overall rating.

Students who do not participate on the problem solving and supervised projects, and do not carry out the short answer questions will score 0 in these sections.

The student will obtain the qualification of No Presented when the student does not assist to the laboratory practice and neither attend to the mixed test.

In the context of "continuous evaluation" the "second opportunity" is a second opportunity of realisation of the mixed test and a specific test related to the laboratory practice. Therefore, the laboratory practice (except for students who did not get a minimum of 5), problem solving, supervised projects and short answer questions will keep the qualifications obtained along the course, whereas the qualification of the mixed test and a specific test related to the laboratory practice corresponding to second opportunity will substitute to those obtained in the first opportunity.

The students evaluated in the "second opportunity" only will be able to opt to Mark Honor if the maximum number of the Honors for the corresponding course has not covered in its whole in the "first opportunity".

For students with recognition of a part-time dedication, the evaluation will be carried out under the same criteria.

For students with academic exemption waiver assistance, conducting laboratory practices is mandatory and they will be provided within the flexibility to allow coordinating schedules and material and human resources. On the other hand, assistance to the greatest number of problem solving sessions will be provided; if students can not attend the problem solving sessions, they will make a mentored work. Therefore, these students will be evaluated by the qualifications obtained in laboratory practice (20%), in the mixed test (55%), in short answer questions (10%), in the activities of the problem solving sessions(10%)and supervised projects (5%). This will be applied to both opportunities.
