The Research And Practice About The Teaching And Learning Strategies Of Trigonometric Functions Under The New Curriculum Standard

The curriculum standard has been promoted and carried out nationwide in 2003, and the high school math teaching also began its self reformation, in which the reformation changed its own system, successively, three times during the large-scale revision. Till now, the new curriculum reformation in teaching material of trigonometric function has left out the slant, difficult, complex, old content in the old class standard(syllabus); the new teaching goals have also abandoned the past traditional teaching methods feeding theoretical knowledge, paying attention to the way of teaching knowledge capacity, and the new requirement is to cultivate students' autonomous exploration, and the quality of the active learning,which puts forward the higher requirements to the teachers and students.Trigonometric function is an important part of high school mathematics, which has not only large capacity of knowledge, various formulas, many property to be understood, but also the main content of college entrance examination each year, it examines how to select the topic, fills up the topic, and a large topic in the form of this part of the difficulty of the subject in the college entrance examination examination paper is moderate, become the students' score point, so both students and teachers should earnestly implement new standard request target. Trigonometric functions and other functions, the function of teaching is the "number" to "shape", and "the number form combining", students are more easy to understand, and trigonometric function of teaching is from "form" to the "number", then "the number shape", students easy to understand, which requires teachers in the teaching of the trigonometric functions on the one hand, the concept of correct understanding of the new curriculum requirements, on the other hand also want to choose the scientific teaching strategies and learning methods, improve the quality of student learning and learning efficiency and teaching level.This article USES the method of literature research, questionnaire investigation and interview and case analysis, under the guidance of basic idea in the new curriculum reform, focus on trigonometric function teaching strategies of the teachers and students learning strategy research and practice, students in the study of trigonometric function through the analysis of the questionnaire problems and difficulties, and puts forward concrete Suggestions on learning strategies; Analysis of the problems of teachers in the teaching of the trigonometric function, put forward their own teaching strategies, supplemented by the concrete teaching case analysis, hope to do well in trigonometric function and teaching for teachers for reference and help.This paper contains the following four parts:Part 1. The putting forward of the problem. This topic proposed background, purpose and meaning. From the new China was founded successively repeated basic education curriculum reform, as a result of the new curriculum reform proposed, on the basis of primary and secondary school education also puts forward new requirements, trigonometric functions as an important part of high school mathematics, according to the university entrance exam this large scale measuring Angle and strength, teachers and students should also be put forward different strategy according to different situation. In this paper, in combination with related literature at home and abroad, this paper discusses the international background of the new curriculum reform and trigonometric functions at home and abroad to study dynamic teaching, both the state, society, schools and teachers should raise the level of middle school education teaching, to cultivate all-round development of highly efficient talent.Part 2. Compare to the old and the new lesson mark under the high school mathematics teaching goal and content of trigonometric function target requirements analysis and comparison between the changes of questionnaire investigation and study, found that students in the learning of trigonometric function still have difficulty, at the same time teachers in teaching and some problems exist in different degrees, this paper also through the reform of the new course standard of high school mathematics requirement and promote the reform of teacher professional development of difficulties and problems are deeply described above.Part 3. Suggestions of the author and analysis of learning strategies combined with the college entrance examination examples,putting forward some strategies and suggestions to the teachers' teaching methods, and through the case "image of sine function and nature" to specific analysis of teaching strategy. Also expounds the author himself in the teaching and learning some thinking on the trigonometric function: under the new curriculum reform, strengthen the high school mathematics teachers in terms of trigonometric functions of accomplishment, and thus improve the efficiency of trigonometric functions of classroom teaching high school is not a simple slogan, it deeply reflected on each knowledge, each teaching process and in each teaching design.Part 4. According to the outline of high school mathematics new curriculum standard and teaching goals and requirements analysis, and a new era of high school carries on the summary and the analysis of the change and development of the trigonometric function, this paper made the summary and reflection. Reform of new curriculum standard is the core of everything for the all-round development of students, teachers should fully attention to seriously study the change of the trigonometric function target under the new curriculum reform requirements, training students' active exploration, discovery, analysis, processing, and the ability to solve the problem, improve the efficiency of classroom teaching, promote the comprehensive development of the education, and promote the continuous development of society and even the whole nation in our country.
