The structure and functions of ETS GRAD Ildar Galeev,
Sergey Sosnovsky Kazan State Technological UniversityThe 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.The importance of mastering the grammar of the German language in the part of
adjective declensions is conditioned by the fact that the knowledge about
adjectives is used both for the synthesis, and for the analysis of a sentence in
German. When a sentence in German is synthesized, the main task at studying
an adjective is to determine its ending correctly. In case of analyzing
(understanding) a sentence in German, the knowledge about adjectives may play
the most important role when a large variety of analysis problems are being
|the subject recognition;|
|the number distinction;|
|the extended sentence identification, etc.|
So, solving the synthesis problems, the learner acquires some sort of knowledge,
which can be also used when analyzing a sentence in German. In this
connection it is worthwhile to design ETS GRAD (GR- Grammatik, AD -
Adjektive) in which a tutorial task represents a set of sentences in German with
the roots of adjectives. The learner has to put the necessary endings in a correct
way. A fragment of a tutorial problem can appear as:
Das klein... Kind trinkt warm... Milch.
