Prerequisites

Suppose knowledge from subject "Materials and technical documentation".

Co-requisites

Not applicable.

Planned learning activities and teaching methods

In education is used tutorial system. Tutorials are guided with using PowerPointové presentation, short video - clips and films and discussion with students. Exercising are divided on laboratory exercise and reckoning exercising. Students behind every tutorial prepare independent work.

Assesment methods and criteria linked to learning outcomes

The students have to work out and hand in a paper on laboratory tasks - maximum 10 points.
Final exam.
The end of term exam is divided in two parts - "Materials in Electrotechnics" and "Industrial Processes". The end of term exam "Material in Electrotechnics" is written, max. 40 points. Test must be done in the end of tutorial at the latest.
The end of term exam "Industrial Processes" is done in the examination period - max. 50 points. The exam is written - 10 tasks, each 5 points.
