Current research activities in TXC

Each group will have to select a topic and present a report following a template describing the problem, analyzing the available solutions and, if necessary, proposing new solutions. Before the first control, the assignment of groups is carried out and the development of the work begins based on research articles assigned by the teacher. It will be monitored as a directed activity. Delivery is before the second check. The evaluation is done according to a rubric for the purpose.

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 the students and their use of the subject will follow the following criteria:

LAB: Laboratory: 20%. It includes the evaluations of the laboratories based on the evaluation of each session. Attendance to laboratory classes is mandatory to be able to evaluate and evaluate yourself.

CO1 and CO2: mod-terms: 65%. The average between the first CO1 mid-term and the second CO2 mid-term will be valued. There is no Final Exam.

TR: Research Work: 15%. The note will be based on a rubric and the quality of the content.

The final grade NF = 0.20*LAB + 0.65*(CO1+CO2)/2+0.15*TR.

The evaluation of the transversal competence G9.3 will be based on the resulting mark between the weighted mark of the controls (60%) and the research work (40%): 0.6* (CO1 + CO2)/2 + 0.4* TR; being : A >=8, B >=6, C >=4, D <4.
