Assesssment methods and criteria:

Classification Type: Quantitativa (0-20)

Evaluation Methodology:
Teaching methodologies: - Lectures; - Solving exercises; - Individual work to evaluation; - Presentation of individual assessment work. Evaluation: - Tests (50%) : the exam are aimed at evaluating the theoretical knowledge and theoretical-practical of students on the subjects taught. - Oral: The oral evaluations are, firstly, in order to develop oral communication skills, and secondly, allow assess knowledge about the contents taught. - Practical assessment (30%): The practical assessment aim to deepen and consolidate an area of knowledge of the subjects taught and allow students to develop writing skills, presentation of results, oral communication and teamwork. - Final practical work (20%): The final practical work allows students to develop research and consolidation of knowledge and verify the students ability to relate material from several chapters to find solutions of the proposed topic. Students have to prepare a report and make a presentation type like a workshop.
