“…Keeping this aspect in mind today, through the use of automated software systems, it is possible to achieve the introduction of automated knowledge assessment systems into the educational process. According to experts, the change in methods and forms of education is a characteristic aspect of information technology [14,15]. This is the opinion of a well-known scientist in the field of education about the importance of quality control of the degree of knowledge: "All aspirations not based on practical reform of the system of testing the circle of knowledge, aimed only at improving the quality of education, as a rule, did not give the expected results.…”

Improving the effectiveness of education in the teaching of computer graphics is the organization of the educational process using new information and communication technologies, as well as quality control of the learning modules. With this in mind, the article provides a theoretical analysis of the methodology of compiling test questions from computer graphics and some related graphic disciplines. The relationship of factor theory to the graphical sciences has been identified. As a result, the three-level test task system structure based on specific formulas and their factors has been studied so far. Also, the system of assessment of students in four categories was tested using a general automated software tool for questionnaires and test control. Based on the results, mathematical statistical analysis was performed, and the range of variation of the four categories was shown.

In the article, the role of graphic programs in the engineering sciences in the educational system, especially in technical higher education institutions, through them, we can see that the issues related to Build Art technologies, which are the demand of today, can be easily and conveniently solved. The ability to analyze the spatial properties and tasks of subjects is an important component of the graphic preparation of students. In the field of graphic education, development of students’ spatial imagination, imaginative analysis of spatial images have been adding a significant share to the creation of content.

Introduction. Construction of hydraulic structures must meet high reliability requirements applicable to water supply channels, free-flow pipes, and open spillways. Any analysis of hydraulic structures must take account of the dynamic properties of flows that the structures accommodate. The theory of one-dimensional free flows, used in practice, has a number of general guidelines, but lack any details. The co-authors take advantage of the theory of two-dimensional free flows, namely, the method of characteristics proposed and developed in the works of I.A. Sherenkov. Materials and methods. In her works, B.T. Emtseva suggests that a uniform flow can be coupled with a general flow only with the help of an intermediate “simple wave” flow, but this statement has no proof. We identified and analyzed a general flow in the plane of the hodograph. Thereafter, characteristics of the first family of the flow were determined. A transition to the physical plane of the flow allowed to determine the coordinates of the points of characteristics of the second family. This allowed to find the coordinates of the points of the extreme streamline and to determine its geometry. Results. The proposed mathematical model complied with the system of equations, describing the flow, and the boundary conditions when it was applied to the boundary problem of the free spreading of a stormy, potential, two-dimensional in plan, free, stationary water flow and its free inflow into a wide horizontal smooth channel. Conclusions. The concept of a general flow (previously unknown) and equations of motion in the plane of the velocity hodograph made it possible to theoretically prove its applicability to the problem of free flow spreading. A simple analytical solution is obtained in the plane of the velocity hodograph. The theoretical significance of this mathematical model consists in the possibility of its step-by-step application to practical problems and its complication from the identification of the main regularities of a simplified model of a potential flow to the practical use of simulation results. The implementation of the methodology in the form of software will make it usable by designers of hydraulic structures. This is the first stage of problem solving, and at further stages resistance will be taken into account.
