The course will be developed through:

Lectures (M1 - Lectures, M2 - Exhibition of theory and general examples and M3 - introductory and troubleshooting activities). The basic concepts of the subject will be presented through multimedia presentations, theoretical presentations, and implementation examples. With a total of 45 contact hours and autonomous work by the student estimated 67.5 horas.En these classes specific skills CEM2, CEM4 and CEM9 well as CB2, CB3, CB5 and CT2 general be developed

Practices (M11 - Solving exercises, M9 - Laboratories). Some content will be explored through activities involving the practical application of knowledge. It will employ a total of 10.0 contact hours and autonomous work by the student estimated 15.0 hours. In these classes CEM2 specific skills will be developed, and CEM9 and general CT2 CT4 CT6 CB4 and CB5 for which the student must submit the document of the corresponding work. Specifically there will be 5 laboratory practices as well as practical classes of exercises in which students will participate actively in the planning and development of them.

Group tutorials (M17 - Clarification of doubts). This activity is organized by short seminars where problems will deepen in some of the topics covered in lectures and doubts resolved alumnos.Con It also aims at strengthening the skills and CT2 CEM2

Seminars (M15 - Seminar). One seminar of some similar themes to the context in which the subject is developed will be organized. This is intended to strengthen the powers CEM2 and CT2

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

As host of evaluation of the course, an exam (80% of the final grade for the course) will be held to assess the skills CT2 CEM2 CB2 and CB3 CEM4 CEM9 CT6. However, in order to boost the ongoing workload and deprive the review has taken into account other evaluation criteria such as attendance and participation in class, reports of laboratory practice and delivery of activities proposed by the teacher, the latter two important processes to assess the skills CT4
CEM2 CT2 and CT6 CB4 CB5 CEM9. Thus the ability to transmit information and self-employment always related to the subject is reinforced.

With regard to the examination, it is necessary that students acquire a minimum score of 4.5 points over 10 to pass the course and take into account the practice califications.

Regarding the practices, to pass the subject is necessary to add that it is compulsory to attend all practices. Also delivering memories practices ( in the stipulated time for it) is absolutely mandatory. In addition, you should obtain an average mark of 5 or higher on the deliverables of them. Additionally, it may not be less than 3.5 in some practice to consider average.

The student could request an evaluation by means of a single test in which the weight of the exam would be 100% whenever justified circumstances arise in accordance with article 13 of the Regulation of Academic Regime and Evaluation of Students of the University of Jaén. The request, accompanied by the justification, must be made during the period in which the teaching of classes is taught.

TEACHING METHODOLOGY AND TRAINING ACTIVITIES

ADDITIONAL RESOURCES TO PRESENTIAL TRADITIONALS:

As synchronous tools the following will be used:
