Way of continuous check of knowledge in the course of semester
•A student will submit the report on the excursions with the description of the visited technology units within 14 days following the excursions.
•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.
