Planned learning activities and teaching methods
Techning methods include lectures, laboratories and student projects. Course is taking advantage of e-learning (Moodle) system. Teaching methods depend on the type of course unit as specified in article 7 of the BUT Rules for Studies and Examinations.
Assesment methods and criteria linked to learning outcomes
Evaluation of study results follows the Rules for Studies and Examinations of BUT and the Dean's Regulation complementing the Rules for Studies and Examinations of BUT.
The maximum of 25 points is given upon completion of the laboratory assignments.
The completion of an individual project adds upto 25 points.
The maximum of 50 points can be gained during the final exam.
