Technology of creation of electronic educational resources for training specialists in digital economy

The professional training of specialists in the field of the digital economy is a promising direction in the development of economic education. The transition to digital technologies in management, banking, manufacturing, commerce, communications determines the emergence of new requirements for the professional and general competencies of university graduates. It is necessary to create an innovative vocational training system based on the use of electronic teaching aids and digital technologies. The implementation of this task should begin with the development of scientifically determined approaches to the creation of teaching aids that take into account all kinds of efficiency factors. This determines the importance of the task of scientific and methodological substantiation of the technology for creating electronic educational resources for the training of specialists in a new format. The paper proposes an analytical approach to determining the content and structure of the basic component of the methodological system – an electronic textbook. The expediency of its use in order to develop necessary competencies of the individual and group levels is substantiated. It is proposed to use a matrix form of information representation and elements of matrix and vector analysis to structure the material. A mathematical model has been developed that describes structural relationships between the concepts of the thesaurus. The structural elements in this model are the glossary concepts of an academic discipline. The possibilities of using the model for unification and automation of information processing during the selection of textbook content in various educational fields are discussed. Examples of using the proposed model in various subject areas are given. The authors describe how to represent a model based on graph theory and methods for solving the problem of the presence of cycles in this semantic structure. The main conclusions and results of the study can be used for the practical development of electronic learning tools, automating the process of structuring their content and methods of use in the educational process.
