Way of continuous check of knowledge in the course of semester
Evaluation criteria are oriented on outputs allowing:
• Reports from selected measurements 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 and problems 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.
