First of them is KMART algorithm, neural network based on Fuzzy ART neural network and the second algorithm is Fuzzy C-Means based on K-Means algorithm. The paper is aimed to compare the quality and performance of both algorithms on the set of real, contextually similar text documents falling into more categories at the same time.

We present in the first part of the paper some results of international ICILS study 2013 related to the digital competences of pupils related to the computer aided education, which use virtual reality and computer simulations. The virtual reality is distinguished by unique sorts of interaction, that responds to users' behaviours and actions.

In first part we want to present some results of international ICILS study 2013 related to the digital competences of pupils related to the computer aided education, which use virtual reality and computer simulations. The virtual reality is distinguished by unique sorts of interaction, that responds to users' behaviours and actions. It is considered to be a new model of computer-based learning that provides the individual learner with a wider range of scientific vision. In mathematics education it is important to represent and visualize various mathematical concepts, relationships and practices including algorithms. Visualization is usually implemented through different models. It is possible to present these models using virtual and remote laboratories. These models may have the form of real mathematical devices, but may also be implemented in a suitable virtual software environment. Virtual modelling has particular importance in the stages of cognitive processes in STEM education.

Significant development of information and communication technologies and especially the Internet... more Significant development of information and communication technologies and especially the Internet boom bring new possibilities in education of different subjects of STEM (Science, Technology, Engineering, and Mathematics). Information technology has provided new innovations to sustain constructing an artificial educational environment by means of computers. Certain artificial environments sometimes go beyond natural environments, such as simulations and virtual reality, which is a sophisticated educational technology. A computer simulation, which enables essential functions of laboratory experiments to be carried out on a computer, is called a virtual laboratory. This simulation support aspect of visualisation in educational process in different school subjects and it is possible to use it in educational process in different study programs at universities including e-learning courses. Understanding of new notions through visualisation belongs to important factors in the constructivist educational approach. The article introduces suggestions for education in this area and deals with the methods, forms and problems of this kind of education.
