The Study On Teaching Of Mathematics Trigonometric Function In High School

The new curriculum reform in the country has entered the implementation stage, The Inner Mongolia Autonomous Region began to implement thecurriculum reform in senior high school from 2009 September.High school mathematics textbooks used in the Inner Mongolia Autonomous Region is the person teaches the version of A version, the trigonometric functions are arranged in a required 4.Trigonometry is caused by needs of astronomy, later to be applied to the field of navigation, geographic, and with their growing up,Gradually into the people solve practical problems of great help, as the development of science and technology essential knowledge.In the high school textbooks trigonometric function is the traditionalcontent, the new reform focused on the generation and developmentprocess of knowledge, so the layout for the content of the trigonometric function in new textbooks changed a lot,.For example:the new teaching material is not set Cotangent, secant and cosecant function of these contents, method and proving many formulahave adjustment,Put some complicated formulas in the old textbooks show in front of students through research, thinking way, let the student independentlycomplete the proof process knowledge and seek the connection between knowledge.At the same time, compared with the old teaching material, is also reduced, the difficulty coefficient of some knowledge requirements such as:induction formula, the basic relationship of trigonometric function of the same angle type, product to sum and difference product formula, but increased a lot of knowledge capacity requirements, like trigonometric function image and the nature of the application ability,In the first chapter of the book required 4 and last festival adds a simpleapplication of trigonometric function model by using the trigonometric function model, strengthen the practical application and the combination of number and shape of mathematics method of thinking, he more prominent ability requirements.lt is precisely because of the ability requirements of the upgrade, led tomany students in the trigonometric function this knowledge of learningobstacles, as they could not cross the chasm.According to the requirements of the new curriculum standard, combined with the method of investigation and practice of using phase, students seeking reasons of trigonometric function learning difficulties, and take positive and effective teaching measures according to the symptoms,gradually improve the teaching situation.This paper specifically divided into the following six parts:The first chapter is an introduction. Discusses the purpose and significance of the study of trigonometric function, simply narrated themethod of Trigonometric function at home and abroad research status and research, to explore the innovation of study.The second chapter is about the study of trigonometric functions related materials. This paper briefly introduced the development history oftrigonometric functions, some changes before and after the importance oftrigonometric function in high school mathematics curriculum in the new curriculum reform and trigonometric function teaching content.The third chapter is the use of a questionnaire survey and trigonometric function test, students find learning difficult reasons of trigonometric function(includ intelligence factors and nonintelligence factors),formation cause analysis.The fourth chapter is an important research part of this paper, combined with the third chapter out of the investigation results and students’ truth,proposes the effective teaching strategies, to create a good teaching atmosphere, improve the effectiveness of classroom teaching, letstudents learn to fight the loss of confidence, get rid of the mathematics learning mental disorder is not good.This chapter focuses on the learning method of basic concepts of trigonometric function; the use of "trigonometric function image","formula" and other methods to help students memory triangle module in the formula; in the teaching with the aid of "multimedia" illustratedexpertise consolidation of trigonometric function image and the understanding, of the nature of; at the same time pay attention to enhance students’ understanding and the ability to use.The fifth chapter summary.This paper summarized the content of this chapter, briefly expounds the framework of the author of the paper,And according to the actual situation of teaching students and teaching strategies, can achieve the desired effect for feedback.Through the student to the teaching feedback of students and the learning state changes, how well we timely records students’learning effect, ground for smooth implementation of the teaching work in the future.Of course, this paper also has many deficiencies to be improved.
