Workshops

Workshops are individual activities with assessment among group members and consist of exercises related to the subject through the virtual campus Athena. Students must solve the exercises and exchange them, a task that makes the Virtual Campus automatically with fellow group basis with deadline for comments.

Final work (Technical report)

The Technical Report is a group activity. Students should develop during the course technical work (Technical Report) in groups of up to three people who gave it to the end of the course. The goal is that students develop the skills of the subject, considering it as a complement to the program itself. Each group chooses the item from the list submitted by the teacher or submit your own theme with the sole condition that it is a complement to the official program and therefore not recorded in the documentation of the course or in any case be a deepening of the topics covered in class. There is an evaluation section that allows students to have a preliminary assessment framework. To facilitate the drafting groups work, Atenea offers to students through Web 2.0 a tool called Wiki to use it as a common repository of documents that are prepared and that will allow them to work remotely. The work also serves to assess the competence G9.3 Critical capacity, assessment capacity.

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, 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:
AC: Class attendance: 5%. Includes physical presence in all activities specified as classes and tests. Minimum of 75 % attendance is required. Otherwise the score will be zero in this section.
PA: Participation: 10%. Includes evaluations of workshops.
CO1 and CO2: Tests: 70%. The average between the first and second test will be assessed.
TR: Technical Report-Lab: 15%. Following a framework, the grade will be based on a test and the quality of content , the contributed bibliography, format required, notes added, clarity, conciseness and capacity of criticism and evaluation.
G9.3 skill assessment is depending on test average : A >=8, B >=6, C >=4, D <4
The final mark NF = 0.05*AC + 0.1*PA + 0.7*(CO1 + CO2)/2 + 0.15*TR.
Students who do not pass the 5 of the tests (CO1+CO2)/2 must do the final exam. In this case, the mark of this exam will replace the average of the tests in the final mark.
