Syllabus Information

5.1. Methodological overview

The learning process has been proposed to encourage continued student work and participation, and focuses on the theoretical and practical aspects to understand, analyze and apply knowledge to solve real problems. In the lectures the theoretical bases that form the subject will develop, solving some model problems. The practices are effective complement to the lectures, allowing verify compression of matter and in turn help the student to acquire a point of view more applied and solve more complex with the help of appropriate resources. Finally, tutored work will complement the above.

5.2. Learning tasks

The learning process is based on the following:

1.- Lectures to the entire group, in which the teacher will explain the basic principles of the subject and resolve some representative problems of implementing the content of the future realistic cases. The participation of students in this activity will be sought. In parallel, the student must perform homework for better utilization of classes.

2.- Computer simulation and laboratory practices are distributed throughout the semester and whose assessment will form part of the final grade for the course. groups of two or three students, thereby learning and group work is encouraged be formed.

3.- Tutored work in small groups (ideally couples): Using a software tool students analyze and solve a problem of the subject. independent learning and group work is enhanced.

4.- Exercise approach, issues and additional problems solved in class: This self-employment is encouraged to study the matter and applying it to the resolution of the exercises. This led, but autonomous execution, activity is essential in the process of student learning and overcoming evaluation activities.

5.- Academic tutoring: The teacher will provide the student certain procedures for approach and resolving doubts. the use of these tutorials is recommended to ensure adequate progress in learning.

5.4. Course planning and calendar

Lectures and solving problems classes are held according to schedule established by the EINA. The practical sessions in the laboratory are given in the schedule and the groups are set depending on the number of students and will be announced at time. The tutored projects are proposed along the course as the issues involved are. In addition, each teacher will report its hours of tutoring.

5.5. Bibliography and recommended resources

Resources

Communication between the student and the teacher will be managed through the platform of Digital Teaching Ring (ADD) of the University of Zaragoza. Here the teacher can distribute course materials (notes, questions, problems, exams, tables, etc.), make announcements and notifications to students, send and receive emails and make available to students the tools for realization in sending reports of learning activities.
