Methodologies
Methodologies Description
Laboratory practice In the laboratory sessions students will carry out the application of the theoretical concepts studied in the classroom. 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 diary of laboratory that collect the calculations, the experimental procedures and the necessary settings. The professor will review the notebook of each student in each laboratory session.
Seminar On site activities for small to very small groups in which the students must participate actively. Seminars will be mostly devoted to solve examples of real problems and numerical excercises. The problems are discussed and solved by the students following the guidance of the instructor.
Guest lecture / keynote speech The teacher will present the fundamental contents of each of the topics. For better learning, students will have to advance the development of these sessions teaching materials suitable for your personal preparation.
Mixed objective/subjective test The test to evaluate the knowlege gained by the student will include both theoretical and numerical questions.

Personalized attention
Methodologies
Seminar
Laboratory practice
Description
The work developed by students in seminars and laboratory practice involves personal attention from the teacher both in the resolution of questions as a guide to the preparation thereof, correction questionnaires, understanding fault indication etc.
In addition, Professor mention to the student individually to discuss in more depth how their learning progress of matter.
Moreover, all students can consult the teacher any aspect of the subject in the tutorial schedule established for this purpose.

Students being recognized officially as partial-time and entitled not to attend the lectures will be attended in a tutorships regime (set hour with teacher in advance).

Assessment
Methodologies Competencies Description Qualification
Seminar A7 A15 A20 A21 A22 A24 A25 B2 B4 C1 It will assess the student's participation, the resolution of problems and numerical excercises, compliance dates for delivery or revision. Some short tests will be done periodically in the seminar sessions and /or guest lecture to assess the evolution of the student. 20
Laboratory practice A7 A15 A17 A18 A19 A20 A22 A23 A24 B2 B3 B4 C6 C8 It will assess the performance of questions, abilities and skills of students in the experimental work, their ability to interpret the results, etc. 20
Mixed objective/subjective test A7 A15 A20 A24 B2 B3 B4 C1 It will assess the student's ability to express, summarize and develop theoretical aspects of the subject and the resolution of problems and numerical exercises. 60
 
Assessment comments

To pass the subject three basic requirements are needed:
1.-The laboratory sessions are mandatory.
2.-Reach a minimum qualification of 5 over 10 in the laboratory practice and in each mixed test.
3. Students who do not participate on the problem solving and do not carry out the short answer questions will score 0 in these sections (20% ).
-In the first and second time, students who not reach 5 points in practices evaluation, have the opportunity to, in addition to the mixed test, perform a specific test related to the labs. The score of this test especcífica replaced the grade obtained in practice for the overall rating.

The student will obtain the qualification of No Presented when the student does not assist to laboratory sessions and to the final mixed exam.

In the context of "continuous evaluation" the "second opportunity of July" is a second opportunity of realisation of the mixed test. Therefore, the laboratory practice, and seminars, will keep the qualifications obtained along the course, whereas the qualification of the mixed test of second opportunity will substitute to the one obtained in the mixed test of the fisrt opportunity.
The students evaluated in the "second opportunity" only will be able to opt to matrícula of honour if the maximum number of these for the corresponding course has not covered in its whole in the "first opportunity". 

- For students with recognition of dedication and part-time academic exemption waiver assistance, conducting laboratory practices are mandatory and it will be provided within the flexibility to allow coordinating schedules and material and human resources. They shall be deemed exempt from the keynote sessions while assistance will be provided to the greatest number of seminars. Therefore, these students will be evaluated by the grades obtained in laboratory practices (20%), in the mixed test (60%) and in the activities of the seminars (20%). If they can not attend the seminars will make a mentored work.
