Description |
Guest lecture / keynote speech |
In the lecture classes the professor will develop the fundamental contents of the program of the subject. The lecture sessions will take place in only one group and will have a length of 50 min.
To make a good use of these sessions, the student will have to prepare previously the fundamental appearances of the topic to treat, employing the educational material (diagram that reflects the contents of each topic), which will be provided to the student through the Moodle platform. The student also will must read the chapter regarding to the topic to treat in the recommended bibliography |
Problem solving |
Classes in very small groups conceived like a group of activities in which the student must participate on a direct way. They are devoted to the resolution of the bulletins of problems, which previously will have been provided to the student through the Moodle platform, and that the students will have to realise of autonomous form for discussion in these classes. Besides, in these sessions any doubts on any appearance related with the lecture sessions will be resolved. |
Seminar |
Initial activity, before beginning the laboratory sessions, which consists on 1 session of 2 hours. In this session, the students will be exposed to the educational methodology that will be employed in the practices of laboratory. |
Laboratory practice |
6 laboratory sessions of 3 hours of length, in which the student will carry out the application of the theoretical concepts studied in the classroom.
Each practice owns a script and a prelaboratory exercise which will be provided to the student (through Moodle) previously to the practice sessions. The realisation of the prelaboratory exercise before starting the laboratory practice is mandatory. The scripts will have questions that the students will have to answer and deliver once finished the practices.
During laboratory sessions, and on a simultaneous way to the realisation of the experiments, the student will have to elaborate a fascicle of laboratory that collect the calculations, the experimental procedures and the necessary settings. The professor will review the notebook of each student in each laboratory session.
|
Short answer questions |
Two exams based on short answer questions will be carried out about two of the topics of the subject. These exams will be realised employing the Moodle platform. |
Mixed objective/subjective test |
A written exam will be realised in the two official announcements of January/July, in which the learning of the student will evaluate by means of questions of theory, applied theory and resolution of problems. |

|
Description |
The classes of problem solving and laboratory practice are conceived like activities in small groups in which the student participates directly. In this way both methodologies let personalised attention to the students allowing a better follow-up and orientation
Besides, along the term an individual tutelage session of roughly half hour of length will be programmed. In this tutelage session, the professor will resolve the doubts which the student may find in the study of the subject and will be able to analyse if the process of learning of the student is suitable.
The students will be able to do use of the schedule of tutelage sessions for asking queries or doubts about the subject |

Qualification
|
Laboratory practice |
A7 A16 A17 A19 A20 A21 A23 A24 B1 B2 B3 B4 B5 C1 C6 |
The qualification obtained in the practices of laboratory will assume the 20% of the qualification of the entire subject. It will be evaluated the suitable realisation of the prelaboratory exercises, the skill in the realisation of the experimental work, the interpretation of the data obtained, as well as the correct realisation of the calculations, the answers to the questions of practices (that they will have to deliver) and the preparation of the notebook of laboratory.

Problem solving |
A7 A16 A20 B1 B2 B4 C1 |
The control of the assistance to these activities, as well as the work realised before and during the same, contribute to the final qualification of the subject with a 10%.
Besides, the evaluation of the learning with regard to the problem solving, also will take place in the mixed test.

Assessment comments |
To pass the subject two basic requirements are needed:
1.-Regular assistance to the evaluables activities. The laboratory sessions are mandatory
2.-Reach a minimum qualification in each one of the evaluables activities. So much for the mixed exam and of brief answer, as for the practices and the classes of problema solving, this minimum qualification will cannot be lower than 4 (over 10).
Anyway, to pass the subject the sum of the qualifications of the different activities cannot be lower than 5 (over 10). The student will obtain the qualification of No Presented when the student had attended less than 25% of the programmed academic activities, and does not assist to the final mixed exam.
In the context of "continuous evaluation" the "second opportunity of July" is a second opportunity of realisation of the mixed test. Therefore, the practices, solution of problems and exams of brief answer will keep the qualifications obtained along the course, whereas the qualification of the mixed test of July will substitute to the obtained in the mixed test of January. The students evaluated in the "second opportunity" only will be able to opt to matrícula of honour if the maximum number of these for the corresponding course has not covered in his whole in the "first opportunity".
Regarding to the next academic courses, the process of education-learning included into the evaluation, is referred to an academic course and, therefore, would go back to begin with a new course, including all the activities and procedures of evaluation that are programmed for the new course.
