The Procedures for the Selection of Knowledge Representation Methods in the 'Virtual University' Distance Learning System

摘要

The advantages of usage and the main functions of the "Virtual University" distance learning system are analyzed, which provides opportunities for planning the processes for course developing, creating and accounting of arbitrary hierarchy of learning objects, accounting of learning outcomes as well as providing interactive communication (forums, graphical chats, virtual classes, trainings, video broadcasts, webinars, etc.). The basic models of the "Virtual University" system prototype as the educational web-based environment of distance learning are presented. The functional structure of the system and the architecture of software and algorithmic complex, which is implemented on the basis of the GPL-license of the developer tools, are disclosed. The most common ways of knowledge presentation are analyzed as well as its parametrization and expert evaluation of the basic characteristics are carried out. A hierarchy analysis method is used to select the method of presenting knowledge in the system of distance education. Our calculations showed that it is suitable to use the ontological representation of knowledge in the "Virtual University" distance learning system.
