Correlation of Educational Material Ontology with the Individual Knowledge Structure of Students

In this paper we experimentally study the influence of the storage structure of the educational material, in particular ontologies, on the effectiveness of its use for students that have various levels of skills. The foreign language is used as a subject domain. The results of the research show that ontological structures are effective for storing the teaching material, but they must be transformable, in order not to cause the conflict with the already̵̵existing̵̵individual̵̵knowledge̵̵structure̵̵of̵̵the̵̵students.
