Forms of Teaching

Lectures

Lectures are conducted in the form of writing and interpreting material on the board, using Power point slides and multimedia content. Numerous examples from engineering practice are also given.

Independent assignments

Students receive a thematic task related to specific elements of the automation system, which includes researching sources on the Internet (web project).

Multimedia and the internet

The students are shown recorded educational films that talk about certain elements of the automation system that they cannot currently meet live in the Laboratory.

Laboratory

In the laboratory for which new laboratory equipment was purchased, students work on two cycles of exercises with pneumatic elements, sensors and laboratory models of a regulated DC electric drive.
