A methodology is proposed for modifying computer ontologies (CO) for electronic courses (EC) in the field of information and communication technologies (ICT) for universities, schools, extracurricular institutions, as well as for the professional retraining of specialists. The methodology includes the modification of CO by representing the formal ontograph of CO in the form of a graph and using techniques for working with the graph to find optimal paths on the graph using applied software (SW). A genetic algorithm (GA) is involved in the search for the optimal CO. This will lead to the division of the ontograph into branches and the ability to calculate the best trajectory in a certain sense through the EC educational material, taking into account the syllabus. An example is considered for the ICT course syllabus in terms of a specific topic covering the design and use of databases. It is concluded that for the full implementation of this methodology, a tool is needed that automates this procedure for developing EC and/or electronic textbooks. An algorithm and a prototype of software tools are also proposed, integrating machine methods of working with CO and graphs.

The paper deals with interdisciplinary connections of mathematics and informatics that occur while teaching students of non-technical specialties (Ecology, Environmental Protection and Balanced Nature Management, International Economics, Management of Organizations) disciplines of the mathematical cycle and computer and information disciplines. It is shown that achieving the goal of formation of a personality, ready for professional, social and other activities that involve system world view, ability to solve problems within the framework of the surrounding reality, using knowledge, techniques and skills formed in different subject areas, is possible with the help of educing interdisciplinary connections in the learning process. At the same time the spreadsheet Microsoft Excel has been chosen for working out the system of interdisciplinary tasks. For implementation of these connections the elaborated electronic textbooks are given. They contain all the basic stages of training: theoretical material, practical tasks with the sequence of their execution, tasks for independent work, references to additional literature, questions for self-monitoring and testing for particular numbers of sections. After passing the tests the mark is given, and it is pointed out which studied sections should be paid special attention to before starting the new topic. Some examples on function graph construction, work with matrices and solving systems of linear and nonlinear equations are considered in detail. Methods and forms of education, control measures, division into lectures and seminars, the results of testing and implementation of the developed system of tasks and electronic textbooks into educational process are given. As a result, due to the usage of interdisciplinary tasks alongside with electronic textbooks for students of non-technical specialities while teaching the disciplines of Economic Informatics, Mathematics for Economists, Higher and Applied Mathematics, Informatics (for professional purposes), Higher Mathematics with Fundamentals of Mathematical Statistics, it is possible to achieve educational and developmental goals; to form information (computer) and analytical competencies; to increase students’ motivation for studying in general; moreover, the number of students involved in scientific-research work is increasing.
