The methodology used in this subject separates lessons in two kinds: theoretical and practical.
Theory lessons basically consist of theoretical explanations of the subject´s contents.
For practical lessons, students are divided into smaller groups with a teacher for each group. They can choose their practical session schedule from a set of options. In order to perform the practical sessions in the audiovisual laboratory and TV, students are divided into groups of three people. Each group has the necessary equipment to perform the practical assignment. Each session is divided in two parts. In the first one, the teacher shows the functioning of the equipment necessary for the session, whereas in the second one, the students use the equipment for the measures. After the session the group hands in a report of the session.
At the end of the course, the reports are corrected, there is an exam of all the practices and the final mark is obtained.
Groups of three people are formed at the beginning of the course and will have to be fixed during all the practices of the course. Therefore, group reports of the practices are a percentage of the individual mark. With this we guarantee a positive interdependence among the members of the group.
The subject is divided in two clearly different parts: one theoretical and the other practical. Each one of these parts is evaluated separately and must be passed independently in order to pass the subject.
If both parts are passed, the final mark is the result of the assessment of 70% for the Theory mark and a 30% for the Practices mark. In the case of failing theory, the subject´s global mark is the theory mark, even if the practices have been passed. In case of not attending one of the two parts (theory or practice) the subject´s mark will be NP (Not Presented).
Evaluation of the theory part:
A. Exams
The mark for the theory part is obtained from the partial exams done during the course. The exams consist on problem solving and theoretical questions.
In this subject there are two partials. In the June exam a second partial is done and also the exam for the first partial if it wasn´t passed on February. The final mark is obtained from the arithmetical mean of the partials, when the mark for each one of them is equal or superior to 4,5.
In the September exam, students will have to do the failed partials. It will be a pass if the mark for each one partial is equal or superior to 4,5 and the mean is equal or superior to 5.
Evaluation of the practical part:
A. Exams
D. Homework
F. Team reports
G. Computer assignments
K. Laboratory reports
L. Laboratory participation
To pass the practical part the following requirements must be done:
- The attendance to the practices sessions is obligatory. If the student cannot attend a session he must recuperate it another day when the laboratory is free, when no practical classes are being given in it.
- Each group must write a laboratory report with the computer for each practice, with the solutions to each section of the practice.
- The reports must be handed in during the course on the established dates.
- At the end of the course there is an exam of all the practices. This is an individual exam and must be passed, independently of the reports, to pass the practical part.
The practices final mark is a 70% for the reports mark and another 30% for the practical exam.
Objective 1
Students must prove to have basic knowledge related to the subject [A, C]
Objective 2
Students must know how to resolve and sign any problems posed in the field of analogue and digital television [D, L]
Objective 3
Students must have the capacity to plan all the tasks related to the practices in order to hand them in on the dates established for each one of the parts forming the practices [D,F,G]
Objective 4
Students must be used to working with the computer (ofimatic tools) and with the C++ programming language (software developing environments) [G]
Objective 5
Students must have the capacity for organization in order to work and promote team work. In the same way, team work provides the possibility of developing the capacity of applying the knowledge acquired to the practical work and being able to solve any problem [A,F]
Objective 6
Students must have the capacity for synthesis in front of all the information received, in order to choose the best elements for the realization of the practices [D,F,K]
