In order for this form of instruction to be successful, highly structuralized and adaptable study materials are essential. As far as the author is concerned, it is a new and demanding way of creating study materials. Therefore, feedback about their quality is of paramount importance. The goal of the paper is to introduce two new methods of automatic evaluation. At the conclusion of instruction, the log about students' behavior in the online mode is analyzed. In the analysis, both statistical methods and data mining are used. The paper describes the theoretical proposition of both types of evaluation and their verification in practice. ER
