GENERAL AND SPECIFIC COMPETENCE
Acquiring knowledge of the laws of fluid behavior required to follow courses in the senior years of study.
STUDENTS' TEACHING OBLIGATIONS AND THEIR PERFORMANCE
Regular participation in classes (lectures, seminars), minimum attendance 75% . Writing papers, homework and seminar assignments.
TEACHING METHODS
Lectures and seminars.
KNOWLEDGE TESTING AND EVALUATION
Continuous assessment of knowledge through two partial written examinations and an oral examination at the end of the lectures. The final grade will be composed of points from the written exam (40%) and oral exam (45%), attendance (5%), and online course activities (homeworks, 10%). Students who do not score at least 50% on all written exams will be required to take the written and oral part of the exam during the regular exam period.
MONITORING OF THE COURSE QUALITY AND SUCCESSFULNESS
University-level student survey. Anonymous surveys to assess individual forms of teaching within the online course during the semester.
