Workshops

The Workshops are individual activities and consist of solving exercises and programming with network simulators, related to the syllabus and through the ATENEA virtual campus. Students will have to solve the exercises and exchange them, a task that the Virtual Campus does automatically, with their classmates at random with a deadline for submission and comments. Attendance at problem class will be mandatory in order to be able to do the co-evaluation process with guarantees.

Teaching methodology

The proposed teaching methodology is based on programming centered learning, cooperative learning, and the Virtual Campus.
1. Programming focuses on learning. Activities in the class session: a) Meeting of temporary groups (for physical proximity in class) to share the doubts last week. Following the interaction of students by the teacher indicating the questionable concepts. b) The teacher will explain the concepts that apply to the program. c) Indication of the studio work outside the classroom. Every two weeks there will be an hour session where problems will be solved by reducing the theory class to 1 hour.
2. Cooperative learning. Students exercise their capabilities in cooperative work developing a technical working in group-based (Technical Report)
3. Campus Atenea. Used in developing the subject in the following aspects: treatment group, documentation class, coassesment workshops, document delivery, monitoring of compliance with delivery dates, forum for exchanging opinions, questions and assignments, resolution surveys.

Evaluation methodology

The evaluation of students and their use of the course will follow the following criteria:

TA: Workshops: 15%. Includes evaluations of workshops based on coassesment. Attendance at workshop classes is mandatory in order to assess and to e assesed in coassessment process in each workshop
CO1 and CO2: Tests: 70%. The average between the first test C1 and second test CO2 will be assessed. If this mark don't allow to pass the course a Final Test will be required and the mark obtained will replace the CO1-Co2 mark average.
TR: Technical Report: 15%.The grade will be based on a framework and the quality of content.
G9.3 skill assessment is depending on test average over10 of ((CO1+CO2)/2 being : A >=8, B >=6, C >=4, D <4
The final mark NF = 0.15*TA + 0.70*(CO1 + CO2)/2 + 0.15*TR.
