Authors in their contribution deal with modeling the behavior of user in e-learning course based on the use of interactive animations. Nowadays, E-learning courses form a standard part of educational process. However, it is not so easy to determine the way students work with study material, whether they make use of it in order to increase didactic effectiveness of e-course. In the contribution authors point to the non-traditional method of recording students' activities and reverse transition to previous lessons using interactive animations, which have been implemented into the study material. The method of recording students' activities was implemented in the academic years 2009/2010 through 2013/2014. Students were divided into two groups--experimental and reference ones. The reference group did not use interactive animations, while in the experimental group interactive animations were implemented into the study material.
