Teaching Methodologies and Assessment Criteria |
At the theoretical classes the course contents are presented through classic methodologies, which can be done by videoconference. The laboratory classrooms are devoted to the conduct of tests and computer model simulations. All need documentation is previously available on Moodle platform. All students who are present in 75% of all classes and obtained positive grade in the practical component are allowed to do the exam. Exemption from final examination is subject to obtaining a minimum grade of 10 (ten), in a maximum grade of 20 (twenty) in the practical component and a minimum grade of 40% in the written test. The continuous evaluation grade is assigned according to: NFreq = 0.75xNT +0.25xNP. The students allowed to do the exam must obtain a minimum grade of 10 (ten), in a maximum grade of 20 (twenty) in the written exam. The final grade is obtained according to: NF = Greatest of {(0.75x NE +0.25xNP);NFreq}.
