Way of continuous check of knowledge in the course of semester

Evaluation criteria are oriented on outputs allowing: • Reports from each measurement processed on the base of measured values from these measurements and their subsequent processing, completing and assessing. • Continuous verifying of student knowledge in the numerical exercises in a form of debate and inquiries to achieve student active participations in study process. Identify, deduce and search of problem solving and their interpretation by students. • Tests from numerical exercises, eventually from chosen theoretical circuits • Term work and projects on a given theme on the basis of selection, investigation, ordering and final compilation of facts and their processing into final form of given theme.
