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

Theoretical evaluation (75%) - Individual written exam, classified from 0 to 20 points.
Practical assessment (25%) - Continuous assessment during the semester. Presentation of reports of the laboratory work.
