TOOL FOR FORMATION OF ELECTRONIC COURSE

Abstract
The work deals with the ontological approach to the formation of the electronic course. There are a number of methods for building an electronic course. They determine the content, form, structure. However, there is no toolkit based on a systematized and structured description of the studied objects. One of the successful approaches to presenting domain knowledge in a formalized form is the ontological one. Ontological aspects of the description include a number of questions, from structuring information and linking objects. To the peculiarities of the ontological description, we note the presence of levels of the hierarchy of concepts and an explicit indication of categories of a more or less high order. The proposed approach is distinguished by the use of computer ontology, which ensures the systematization of the concepts under study taking into account their interrelationship. Computer ontology provides effective computer processing of knowledge and allows to build a system of automated design of electronic courses, which uses the ontology of subject discipline and methods of visualization of ontology. On the basis of computer ontology, you can also build a system for automated synthesis of test problems. Unlike the usual subjective approach, the ontological approach presupposes strict structuring of terms and concepts. The ontological knowledge base ensures the unity of the interdisciplinary knowledge space. Computer ontologies are used to automate the selection of ontograf concepts that are studied in the electronic course and descriptions of these concepts. An algorithm for constructing an electronic course is presented, which implements the aforementioned ontological approach. Concepts isolated from the ontograph of the subject area of the discipline under study are used to structure the electronic course. Descriptions of the selected concepts are included in the textual building of the electronic course. It is possible to add teacher's comments (explanations, references to drawings, additional materials). To place the lecture in a modular object-oriented dynamic learning environment Moodle a converter is used.
