Development of Tools for Automatization of Training Tasks Generation and Answers Processing in the Interactive Educational System

The problem of interactive educational systems development and the problem of automatization of training tasks generation are considered in this work. Nowadays there are plenty of products supporting educational process in different ways. However some problems still remain unsolved. The problem of training tasks organization, delivery and support in case of disciplines involving mathematics is one of them. This paper is divided into two main parts. The first part provides an overview and analysis of different electronic educational systems. Advantages and disadvantages of such systems are examined, and an analysis of structure of systems of such a kind is provided. Some programs that may be useful in interactive educational systems development are considered. The second section reveals an approach to training task organization. The notion of task templates is explained, and the process of training tasks generation is considered. The problem of automatic answer checking is considered further in this part. Namely, we consider the problem of checking an answer given in mathematical notation. It appears that this problem in formally unsolvable. On order to cope with its circumstances, and additional checking algorithm is suggested. We show that with high probability such an algorithm helps to make a correct decision when checking an answer. A detailed analysis of this algorithm error is provided.
