| This article mainly discusses the author’s research on stratified teaching.Because of the students’ individual differences in all aspects,in order to make the students better learn the ideal knowledge,our teachers have to find the ways and means suitable for them to teach,thus the stratified teaching has appeared.It is believed that many people who know the teaching of mathematics in high school are not strange to the trigonometric function.It is difficult for many people to mention trigonometric functions,but it is the required content of the new curriculum standards at present,and it is also the key examination link of the present high school mathematics examination.Because the content of this chapter is more and more complex,the logical relation between the formulas is relatively close,the transformation skill between the formulas is strong and the comprehensive ability of the scholar is higher,so the section of trigonometric function is always a great obstacle in the mathematics learning of the high school students.The trigonometric function is currently placed in the compulsory four of high school textbooks,usually starting at the beginning of the semester.The difficulty of solving the chapter of trigonometric function is of great significance to the students’ high school and the whole high school mathematics learning.Because mathematics is a whole line,and a link without understanding will affect the learning of the rear.Therefore,the study of "teaching students in accordance with their aptitude" in trigonometric function section has a very far-reaching impact on our high school mathematics teaching.This paper mainly discusses the use of trigonometric functions in my teaching.I mainly use one of my present classes to practice stealth stratified teaching in the class,which not only protects the self-esteem of the students,but also will not be opposed by parents,and it is also beneficial to students’ learning.The stratified teaching of the previous studies is theoretically speaking,and there is no practice.I have done the theory and practice.Finally,the students’ achievement has been obviously improved after the use of stratified teaching.This proves that our reasonable level of teaching is indeed conducive to students’ learning. |
