    Problem formulation. Educational researches of technologically actual and perspective models of devices with the use of simulation environments have allocated a special didactic niche. The demand for NI Multisim as a propaedeutic tool for the formation of engineering skills requires a study of the organizational and methodological foundations of its integration into the modern educational environment. Materials and methods. Theoretical (comparative analysis of scientific data, modeling of the methodical system of learning using simulation environments, etc.), empirical (mostly observational) methods, as well as computer modeling of the studied devices were used. Preliminary didactic approbation was carried out within the framework of the project "Summer Physical and Technical Schools" of the National Center "Junior Academy of Sciences of Ukraine". Results. Features of the supercapacitor as a means of learning the basics of electronics using the STEM approach are systematized in the form of a structural and functional diagram. The educational method is based on the use of the equivalent circuit. The virtual study of serial supercapacitors consists of calculation of parameters and construction of an equivalent circuit in the NI Multisim environment, analysis of charging (discharging) characteristics, and their dependence on external (internal) factors. By the instrumentality of a real experiment, it is possible to determine the specific energy consumption of the supercapacitor also. The technique of using a printed model of the supercapacitor complements the experiment with the possibility to determine the specific capacity of the carbon material, the impact of the concentration of the electrolyte used on the characteristics of the device. 3D printing can be a part of an educational STEM project. Conclusions. Techniques based on the creation of equivalent circuits with simulation environments provide the potential to design educational studies of properties and related processes of a real, serial device, as well as of one manufactured in the laboratory. The possibility of using passport data of serial products creates didactic opportunities for the transition from an algorithmic laboratory project to independent educational research, in particular, distance or mobile learning. Relevant techniques based on 3D printing, as well as pedagogical aspects of STEM-oriented learning of the basics of electronics, require further research.
