Teaching method
Teaching methods include:
a) exposure of the theoretical concepts, using the data show;
b) practical classes, in which students are encourage to solve problems which are focused on the interpretation of practical
evidence based on the theoretical principles and concepts studied;
c) laboratory classes, where students have the opportunity to run experiments where they apply the knowledge given in the
theoretical classes;
d) use of a website with study material and documents and remote contact via email.
Evaluation method
The approval to this course implies individual approval to each of the components: theoretical and practical, where each component must have a grade equal or higher than 9.5 points. The practical grade gives the class attendance of the UC.
Theoretical - 75% for final mark
Individual written exam.
Possibility of a second exam in case of failure in the first.
This 2nd exam doesn''''t give the possibility to be used for improvement.
Practical - 25%.
Each student has to do all practical work and present a report on one of them of his choice.
