«Первая четверть тригонометрической окружности»

           The series «Первая четверть тригонометрической окружности»
from collection «Learn to read Russian mathematical texts» carries on the line of forming elementary lexical skills and basic ideas of russian mathematical terminology.

           These films can be reproduced on any computer having WINDOWS version 95 (and higher versions) without an additional installation of special programmes as they are made in EXE format.
           The principle of operation: the changing of frames is executed by pushing of a printed (graphical) button. Movement is is possible both “forward” and “backward”.

           The series is worked out for using by a teacher at lectures and practical studies in groups of mathematical fields of pedagogical higher school’ s physico-mathematical faculties and forms of schools with profound study of mathematics.

           The main aim of the series. Its direction is determined by strictly preventing aims. The films are meant to form elementary lexico-grammatical skills of students of not-philological fields onto the material giving the elementary idea of russian mathematical terminology. The content and the purpose of the series is determined by strictly preventing aim and is directed to learning of special terminology.
          

           The texts are given in different versions of translation: from Russian into English, from English into Russian (in sequences), in Russian only.

           A special feature of methodical purposefulness of the series. The effectiveness of teaching is reached this way: visual and text learning information presented ot the screen join in one whole available to the learner’s visual perception.Terseness of the text and the apperance concentrates the attention of the learner’s onto the main elements of the learning material that promotes quicker assimilation of the offered material by students.

Первая четверть тригонометрической окружности

       Slide-film «Замечательные углы первой четверти тригонометрической окружности» begins meeting the first quarter of the trigonimetrical circumference and basic russian mathematical terminology,which allows to describe.

       The small number of freqently repeating terms allows to assimilate and remember all the neccessary lexical units.

       The slide-film «Радианная мера замечательных углов первой четверти тригонометрической окружности» contains more difficult language material with the help of which the ways of finding the radian measurement of the remarkable angles of the first quarter of the trigonometrical circumference are determined.

       The widening of speech units stock happens here, a number of adjectives is brought into together with new nouns.
