Research On The Arrangement Of Trigonometric Functions In The New And Old Textbooks Of Senior High School Mathematics Teaching A Edition

The core guiding ideology of the 2003 curriculum standard and the 2017 curriculum standard is based on the development of students.The 2003 edition of the curriculum standard emphasizes the importance of students' ability development in the process of education and teaching.The 2017 version of the curriculum standard emphasizes the importance of cultivating students' core qualities and the importance of process evaluation,especially in the aspect of moral education.Trigonometric functions as a kind of basic elementary function,plays an important role in the high school math,it not only is the important tie is algebra and geometry,but also students in elementary education come into contact with the most basic,the most typical kind of periodic function,so for the order of trigonometric function in the teaching material and teachers' understanding of the content of the trigonometric functions are largely affect the students' understanding of knowledge,to improve teachers' teaching material layout analysis about the importance of teaching material analysis,enhance the learning ability of students.This paper mainly uses literature research method,text analysis method,questionnaire survey method,interview method and ISM method(explanatory structure model method)to study the content arrangement of trigonometric functions in new and old textbooks.The main research contents of this paper are as follows:Firstly,PEP A edition is the most widely used edition of textbooks in China.Therefore,this paper selects trigonometric functions in the mathematics textbooks,which are both PEP A edition and compiled according to different curriculum standards,as the research object and makes A comparative analysis of the two versions of textbooks.Secondly,the views and suggestions of the front-line teachers who have used the new textbooks on the content arrangement of trigonometric functions in the new and old textbooks are investigated to understand the actual use of the textbooks.Finally,this paper studies the arrangement of trigonometric functions in the new textbook by using ISM method,and probes into the rationality of the present arrangement of the textbook,so as to provide reference for the arrangement of the textbook.Through the study,it is concluded that the arrangement of trigonometric functions in the new textbook is very reasonable,and it improves many deficiencies in the compilation of the old textbook.Finally,it gives some suggestions on the arrangement of the textbook:from the perspective of students,the arrangement of the textbook should pay attention to the students' understanding and accepting ability of knowledge;From the point of view of the arrangement of teaching materials,the arrangement of teaching materials should pay attention to the logic and cohesion of the knowledge itself,as well as the actual learning situation of students.From the perspective of teachers,on the basis of mastering the intention of textbook arrangement,teachers should adjust their own teaching progress and teaching order in combination with the actual situation of students,so as to maximize the role of knowledge.
