For an electronic textbook on information and communication technologies (ICT), methodological foundations for the design of electronic courses in the field of ICT based on an ontological model for the implementation of information technologies for automated processing of ontologies are proposed. It is shown that the ontological model is designed to implement information technologies for automated computerized processing of ontologies of subject areas (VSS) using the example of ICT, which allows updating this content as the VSS develops on the basis of relevant content in the field of information and communication technologies corresponding to the current state of this subject area, using electronic courses (EC) and/or electronic textbooks (ETS) simplify the procedures associated with the implementation. On the basis of computer ontologies, a functional and information model of processes is implemented that form a combination of information technologies for automated processing of ontologies of subject areas characteristic of the field of information and communication technologies. Modeling technologies were also analyzed, in particular, technologies such as IDEF, DFD, UML were considered, which can be used in the design of complex systems such as EC and/or EO in the field of information and communication technologies for high school students. The results obtained in the course of the study are primarily aimed at improving the effectiveness of the preparation of electronic courses and/or electronic textbooks in the field of ICT for secondary school students. However, the results presented in the article can be used both to create EC and/or EO, as well as for other subject areas characterized by a high level of formalization of knowledge description and the presence of computer ontologies of these subject-disciplinary areas.
