Planned learning activities and teaching methods
Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.
Teaching consists of lectures, laboratories and numerical exercises. The communication platform of the course is on e-learning. Students pass five laboratory exercises. Planning is one specialized excursion.
Assesment methods and criteria linked to learning outcomes
Point scoring of written and oral examination is held under the rules of FEEC.
During the semester, students are obliged to pass five homeworks (30 points), four laboratory tasks (20 points). Requirements to get the credit are to obtain at least 25 points from 500 possible and NONE of the required activities is evaluated with 0 points.
The final exam is evaluated by up to 50 points and is divided into written (arithmetical problems) and an oral part. Necessary requirement to pass the examination is to obtain at least 10 points from the written part and at least 15 points from the oral part.
