This article describes a solution for learning how to build the method of frequency characteristics of the control object. Nowadays, the level of competencies required in the work of a modern engineer is becoming higher and higher, and the more difficult it is to provide the necessary level of knowledge and skills using only the traditional approach. This problem can be solved by implementing automated learning systems that will relieve teachers, reach more students, and unify the quality of work. The subject of the research is the possibility of building a certain abstract system that will be able to provide complex skills for students in an automatic mode. The basis for this research is a complex task that requires various skills from the learner.  As a system that requires well-developed skills, we can cite the system of construction of the frequency characteristics of the control object. This work studied the methods for building such systems, as well as to study the learning ability of students and for extracting the most frequent and possible errors of students. The goal is to design and run a system that allows the student to acquire skills in constructing the frequency characteristics of an object. This work allows use of one of the possible methods for implementing such a task, as well as identifying the most common problems at the stage of learning this technique and the most successful method to prepare the system for use. In the process of the task, the following results were obtained: student errors were identified and classified. Based on the signal-parametric approach to the diagnosis of faults in dynamic systems, mathematical diagnostic models were created, that allow the system to identify classes of errors by comparing the calculation results of the student and the calculation results of the system. The peculiarities of the application of the proposed diagnostic models are presented. The intelligent tutor system is developed and used in practical classes on "Theory of automatic control" by third-year students of the National Aerospace University “Kharkiv Aviation Institute”.

The existing education system (in particular higher education) due to its focus on basic knowledge is quite inert and cannot satisfy the needs of the modern labor market, which is rapidly developing. Some professions transform or disappear, while the others appear almost every day. Today the employers need specialists with certain skills and abilities, who are able to develop them and adapt to specific projects. That is why short-term courses are very popular today, especially online and with a mentor — a specialist in a particular field. At the same time, graduates of such courses are mostly unable to solve complex problems and make competent decisions on their own. There is a requirement of creation of training programs for testing the development and implementation of tools for productive knowledge and skills transferring in a particular field. The article shows a possible approach to provide some interactivity to computer tutoring tools in addition to the game principle, information visualization and other techniques that have already proven themselves in information systems. It will give an opportunity to create a platform that can accumulate new technologies, integrating them into a digital tutoring environment that can be adapted to each student.
