چکیده
The urgency of computer-assisted technologies for teaching natural languages (NL), and first of all foreign languages, is constantly growing. To denote computer-assisted teaching NL a special term – CALL (Computer Assisted Languages Learning) has appeared and is widely used now. The chief disadvantage of the currently available systems of teaching NL is their moderate adaptivity to the learner’s individual characteristic features. To overcome the mentioned drawback, it is necessary to develop expert tutoring systems (ETS) which dynamically form a tutoring program in accordance with the learner’s being-trained level, in contrast to traditional computer systems functioning in conformity with a strict, preset scenario.
