Teaching Methodologies and Assessment Criteria |
The course is structured with theoretical classes and practical-laboratory classes. In the theoretical classes, theoretical and technological knowledge, associated with the syllabus of the curricular unit, is transmitted and examples are presented to illustrate the main functions of each application, encouraging discussion and problem solving. The practical-laboratory classes take place in the laboratories that support the functioning of the curricular unit, where the student will carry out various experimental works with practical application of theoretical and technological knowledge. At the end of each experimental work, students prepare a written report describing the processes applied and a reasoned discussion of the results obtained. The curricular unit assessment consists of a written test (during the teaching-learning period) with a weight of 50%, and the continuous assessment of the laboratory component (including reports and discussion) with a weight of 50 %.
