The paper describes software packages National Instrument Multisim and DasyLab. The former can be applied for designing, testing and simulations of electronic and digital elements and systems. The latter is used for designing virtual measuring systems for obtaining measuring data from real objects and measuring sensors. Both software packages can be fruitfully applied in research and in the teaching of technology-related subjects. The paper presents examples of both kinds of applications of the software under scrutiny.

<p class="Abstract"><em><span lang="EN-US">The teaching of subjects connected with electricity, such as electrotechnics or electronics is an important part of school and technical university curricula. Due to the recent development of computer technology, laboratory exercises can be performed through simulation. Such simulations can be performed in a virtual environment measurement. <br /> The paper presents an example simulation process of a measuring system in the software environment DasyLab.</span></em></p>

Integrated software packages, such as National Instruments Multisim or DasyLab can be successfully applied in developing research projects and in teaching. Thanks to their intuitive use and wide potential they can be utilised as support for simulation and other programmes. They are also often applied for comparative analysis of real measurement results with computer simulations. Apart from that, they can also be useful in a research or experimental lab.

The article presents the methodology of laboratory tests carried out in the Laboratory of Experimental Research Biofeedback of the Jan Dlugosz University in Czestochowa (Poland) regarding the evaluation of education effectiveness by registering brain wave activity using electroencephalographic research (EEG method). The research results indicate that, depending on the form of the computer program visualization, a change in the activity of SMR, Beta1, Beta2 and Gamma waves was observed. The results are presented in the form of graphs and 2D brain activity images using the equipment Mitsar EEG 202 and WinEEG software
