Abstract: The paper discusses the problem of the effective ways of formation of the Natural Science students’ knowledge about the probabilistic way of describing the state and behavior of real objects. It is emphasized that the pilot study and confirmation of the statistical regularities is difficult because of the limited number of relevant works in the traditional laboratory course. In this context, we propose an approach in which a study of the basic characteristics of the probabilistic method is based on the combination of features of the experiment and the use of modern computer tools. To reach this goal, the description of the new academic experiment of the distribution of photoelectrons is provided, as well as a step-by-step algorithm of computer processing of experimental results. It is shown that the use of computer equipment allows to study in detail transformation of the distribution function of the particle kinetic and potential energy depending on the change of the key system parameters and to obtain the distribution function of the system of full energy. The question about the opportunities of the use of computer tools to describe electrons in the atom is raised. The ability to visualize electron orbitals for the hydrogen atom is proved. The conclusion is made about expediency of use of the results of this research in teaching practice.
