Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

1. compare grounding systems in low-voltage installations, explain types of protection against direct and indirect voltage contact in low-voltage installations, explain elements and the system of operation in advanced

2. explain the basic lighting-related measures, compare light sources with respect to technology, interpret interior and exterior lighting characteristics as well as control and monitoring systems

3. calculate voltage drop and select cross-section of connection lines. Calculate indirect contact protection

4. examine the safety of low voltage installation, design a lighting project for a classroom, sports hall and an intersection
