The Old And New Version Of The Two High School Mathematics Textbooks Trigonometric Function Of The Comparative Study

In the ongoing new round of Curriculum and teaching materials used in the previous version of the materials have been greatly different. Two editions of textbooks What is the difference ? What are the characteristics of their respective ? What are the success and shortcomings ? Discussion on these issues on China's reform and mathematics curriculum materials for the preparation of the future have far-reaching significance.Characterization of the objective world is a function of changes in the laws of mathematical models, different changes in the law should be used to describe different functions. Trigonometric function is the description of the objective world in the cyclical changes of the important mathematical model in mathematics and other fields play an important role, it is in senior high school students learn another important category of basic elementary function.Based on these teaching materials version of the trigonometric function part of a comprehensive comparison, the following major conclusions:Looking at these two version of teaching materials, teaching materials on a version of the main features of the trigonometric functions are: the content of the traditional triangle made substantial streamlining ;highlights the mathematical thinking and mathematical methods ; focus on improving the ability of students.; to the strengthening of linking theory with reality . New materials and the characteristics of success: the infiltration of a better mathematical humanistic ideas to the development of student-centered thinking; to strengthen geometric intuitive, thinking that Shuoxingjiege; that describe the real world trigonometric function as a cycle of a mathematical model of thinking.; highlight the mathematical way of thinking, in analog, promotion, special privileges, such as general logical thinking to guide the way; the proper use of information technology.
