Comparison of virtual and real electronic measurement

Abstract

This contribution deals with comparison of possibilities of realization basic electrotechnic and electronic measurements. Preparation of teachers of scientific technical subjects at the elementary and secondary schools is becoming more and more difficult. In the case of electrotechnics, when theory must be supplemented by many experiments and measurements, several possibilities are available how to reach effectiveness needed. Real parts of machines and measuring devices can be used for developing real knowledge and experiences. Nevertheless, this method requires equipped laboratories, maintenance of laboratory tools and devices. Transition of experiments and measurements into virtual reality is the last possibility. There are plenty of computer programs which are able to simulate even the entire laboratory. Authors created several tasks which were realized by the students using all way mentioned. Followings, authors evaluated results and approaches of the students to various methods of measuring.
