Teaching Design Of Mathematical Trigonometric Function In Senior High School

Trigonometric function is one of the high school mathematics teaching material part basic elementary function, it plays an important role in the high school mathematics.It communicates a high school algebra and geometry, is linked to the people’s life and work. It is conducive to better solve the practical problems in life, and the other is closely connected with the edge discipline again at the same time.Trigonometric functions of learning is beneficial to students a better understanding of the function, which can cultivate the students’ mathematical thinking ability and application ability. The purpose of this paper through the study of trigonometric function is to find out the problems existing in the high school teaching of trigonometric function, based on the theory of teaching, practical teaching in the teaching design and efficient classroom excellent intellectualize, to study and put forward effective Suggestions and methods of instructional design, causes the student to study trigonometric function can be more profound understanding of knowledge, to achieve flexible application, training students’ application consciousness and innovation consciousness, grasp mathematical discovery process, cultivate the students’ interest in mathematics. Combined with trigonometric function definition, image and nature of research how to make reasonable teaching design, and operational teaching design case is given. Whether these teaching designs can form a unified template, teaching case, improve the class efficiency and achieve efficient class.This article uses the research method is: interview method, literature method and case method. By investigating the trigonometric function under the new concept of teaching and learning situation, based on the trigonometric function teaching research status in China and combined with trigonometric functions. Furthermore to analysis design method of teaching, and with the concept of trigonometric function, image and properties, application of trigonometric function model as an example, explores the specific teaching design case of trigonometric functions.In this study, the main research question is:(1) in the study of the concept of trigonometric function, the students easy fault point and the reason for the error analysis;(2) in terms of trigonometric function application, the students master the analysis of the situation;(3) the teaching design of trigonometric function;(4) based on the research process and get the conclusion to puts forward related Suggestions. Through the study of this article, the conclusion is:(1) to realize the importance of teaching design to improve the classroom efficiency;(2) to study curriculum, flexible use of teaching materials;(3) the design of classroom teaching to students as the main body;(4) to notice to mathematical concepts, formulas and conclusions in the process of the generation and development of the teaching design;(5) the rational use of multimedia can increase classroom capacity, improve efficiency. In this paper, the study of trigonometric function teaching design, can improve teachers’ own theoretical accomplishment and practice level, improve the classroom efficiency, also provide methods to cultivate students’ mathematical thinking ability, at the same time hope to offer a glimmer of teachers teaching help.
