Study On Strategies For Senior One Students' Operation Ability Training Of Trigonometric Function

Trigonometric function is one of the most important content of high school mathematics.While the ability of calculation is one of the main factors that affect students' mathematics achievement.However,senior one is the key stage to connect junior and high school,is the key stage to develop the mathematics' ability of calculation.In reality,there are many problems for students to make fertile use of trigonometric function to solve problems.Therefore,it is very meaningful to study the present situation of trigonometric function calculation ability of high school students and put forward the training ways.Based on the investigation of the main problems existing in the calculation of trigonometric functions,the author analyzes the factors that affect the development of the trigonometric function calculation ability of the students and puts forward some countermeasures to improve the ability of solving the trigonometric functions.According to the new curriculum standards and the actual situation of the students,the author makes a test of the ability of solving trigonometric functions with parts of the senior one students,also has an interview with some teachers and students,and finds that there are three main reasons for the low ability of trigonometric function calculation in the first grade students;first,teaching materials;second,the students' reasons;finally,the teachers' reasons.On the basis of some experts and teachers' theoretical and practical experience and their research results,and also according to the author's own teaching and practical experience.There are some countermeasures for students to improve the ability of solving trigonometric functions: pay more attention to the basic knowledge and basic skills,improve the accuracy of calculation;insist on thinking training,improve the rationality and simplicity of calculation;clear the algorithm and cultivate the ability to choose reasonable algorithm;correctly handle the relationship among three pairs of contradictions,cultivate students' ability of rapid calculation;strengthen the teaching of mathematics thought;pay attention to the cultivation of non-intellectual factors of students,improve students' ability to solve.This study can provide some reference value for the teaching of trigonometric functions for high school first-line mathematics teachers,so that students can achieve the correct and reasonable operation,and then simple,rapid and finally achieve the purpose of flexible operation,lay the foundation for future mathematics learning.
