A Comparative Study About The Trigonometric Function Of Senior High School Mathematical Textbook Xiang Version And Renjiao Version A

Since the 21st century, all countries in the world have issued a new education policy, promote the reform of mathematical education of China. China’s education reform has made delightful achievements. And in April 2003, promulgated the ordinary high school mathematics curriculum standard (trial) "(new standard), in 2004 officially start the high school curriculum reform, according to the basic concept of the new standard and requirements, there are 5 this by textbooks authorized committee authorized by the teaching material. Chose two sets of teaching materials, xiang textbooks and renjiao A version. What are the similarities and differences between the two sets of teaching materials? What are some of the characteristics of each? What are the successes and shortcomings? These issues research for our country high school mathematics teaching material in the modification of trigonometric function part, write to provide reference and reference.Function in the high school mathematics in the important position, plays a dominant role. Functions are important mathematical model for describing the dependency relationship between variables, it’s ideas throughout the high school. And trigonometric function is one of the basic elementary function, it is one of the important mathematical model describes cyclical phenomenon, play an important role in mathematics and other fields. The study of trigonometric functions is to deepen students further understanding of the function definition, to deepen of periodic function and function thought, thus improving the students to use the concept of function is the ability to solve the problem. This article through to high school textbooks, xiang version、renjiaoA version of the teaching material the comparison of trigonometric function part, conclusion is as follows:1. The two versions columns on each has its own characteristics. Various styles of charts are set up, pay attention to the combination of number and shape. Two versions in the mathematics culture, mathematical modeling and mathematical experiment, information technology and the integration of teaching materials, problem sets the topic quantity, difficulty, material, etc.2. Xiang version of materials highlight mathematics and nature, between mathematics and other subjects and social contact. History, mathematics culture in mathematics, mathematical modeling and mathematical experiment in the chapters of penetration, let the students understand the nature of mathematics, mathematical aesthetic value, feel useful, is useful to learn mathematics, inspire students’ interest in learning mathematics, developing innovative consciousness, improve the practice ability.3.Renjiao A version of the teaching material content set all kinds of questions, to explore, through the way to let students think actively and let the students form the ability of independent thinking, improve thinking ability, stimulate students’ interest in learning. Relatively systematic knowledge arrangement, the use of the information technology, the students based on the idea of information technology has also been fully reflected, guide the students with the aid of mathematical problems related to information technology research, and use it for problem solving.
