Assesssment methods and criteria:
Classification Type: Quantitativa (0-20)
This UC comprises of 24 hours of lectures spread over 16 weeks and 70 h of lab practice, spread over 14 weeks (2 blocks of 3 hours per week). In the theoretical classes, the professor makes use of multimedia projection, white board and demonstration with various materials. The practical classes are laboratory sessions where groups of students apply the techniques under study to concrete cases. The filling in of post-lab questionnaires ("reports") is made at the end of each session or group of sessions Evaluation in this UC consists of: a) written tests (2) weight of 30%); The minimum score on each test is of 8 values. b) continuous evaluation in the practical classes, based on the development and delivery of questionnaires, preparations of each work, performance during sessions, elaboration and timely delivery of reports and response to proposed application exercises. All these elements are grouped in the Lab Manual (weight of 70%).
