To describe the management of communication between human being and the computer it is appropriate to employ graphic tools in order to describe and formulate the basic rules underlying this interaction. Interaction between student and LMS in the process of teaching and learning is a composite process and it is highly recommended to employ Petri nets for this purpose. The paper aims at presenting the principle of construction of linear and branching learning programmes and their subsequent formulation using Petri nets in education of natural science subjects. At present, didactic effectiveness of the e-learning course „Operating systems“ is verified based on the model created by means of Petri nets. In order not to diminish the power of statistic results of created tests, we shall verify their validity and we shall use reliable and valid measuring procedures for data mining (pretest, posttest) (Munková, Munk, 2007). For the solution of this research problem two methods will be used: analysis of variance and analysis of covariance, where the analysis of variance is more simple and does not require the assumption of the homogeneity of regression in individual groups. On the other hand, interpretation is less valid, when between groups exist differences in the controlled variable (pretest) (Munk, 2007). Similarly to other situations it is recommended to execute both ways of analysing and comparing their results. On condition that the results will be identical we can consider them robust. In order to apply new forms and methods of teaching the subject from the area of operating systems of computers, we had to analyse the current state and contents of education process from this subject. After the survey a certain model was designed, which could cause shortening of the progression and increasing of the visualisation of instruction of operating systems, which results in the increase in the knowledge level of students and improves the level of their seminary and final works. The created e-course dealing with operating systems of computers is used as a complementary study material and an aid for the instruction of the subject „Principles of construction of operating systems“ for students with the focus on informatics. The current results point out to the suitability of application of Petri nets to the creation of instruction supporting e-materials for the students of informatics study programmes realized at the Department of Informatics of the Faculty of Natural Sciences of the CPU in Nitra.
