Classification Type: Quantitativa (0-20)
Blackboard will be used in theoretical classes to show the contents. The video projector will be used to display pictures, graphs and tables. Tutorial method will be used to follow students in solving problems. In laboratory classes students perform experimental work guided by previously established protocols. The assessment of this course is based on two modules; the students must obtain a grade of at least 9.5 marks in each module: - Theory module, with a weight of 75% on the final grade of the course; - Laboratory module, with a weight of 25% on the final grade of the course. The Theory module is graded by means of two written exams. Each exam has a weight of 37.5% on the final grade of the course. The Laboratory module is graded by two practical exams. Each exam has a weight of 12.5% on the final grade of the course.
