Abstract

Throughout the past, the development of modern mathematics we can see, the function is to describe the movement, change the basic concepts of mathematics, many of the concepts or derived from function, or commanded by the function, or can be attributed as a function of opinion research. It can be said that the generation of the concept of function itself marks a major turning point of the mathematical way of thinking - mathematical constant to variable mathematics. Function of the application, but also makes the face of the mathematical object to the theory, methods, structure, the occurrence of a fundamental change. For these reasons, the purpose of middle school mathematics, the importance of the function is indisputable, it has become a link in the middle school mathematics, but at the same time it is also one of the hardest to understand students. So, how should develop students' concept of function? Preparation of teaching materials how best to help students form the concept of function? Absorption on the basis of the research of others, \materials function as the research object, the main research the following: 1, two sets of textbooks function is presented in the overall comparison. Inequality arranged in the order from the function chapters arrangements \PEP old textbook function knowledge of the logical structure of organizations teaching materials \The North Division edition of the textbook the function chapter selection criteria steering learners, steering the context of the learner's cognitive status and role of the steering function in social life; constructed to function as the main line of function and equation, inequality interconnected body of knowledge. 2, two sets of textbooks function is presented in the specific issues. By two sets of textbooks from two aspects of the concept of function processing and image processing function, we can find, the PEP old textbooks more abstract speculation focus on the concept of function and function as a logical the main method of mathematical knowledge, emphasis on understanding and mastery of the function expression. Function Image will draw function image function image analysis functions in nature. North Division version of the materials for the penetration of the concept of function, create, deepen, to focus on the introduction by the number of forms in real-life situations, pay attention to the function of various forms of representation, focusing on functions and equations, inequalities contact; function image as a function concept the contents of one of great importance to the understanding and application of image analysis as a function of the practical problems to solve real-life problems. 3, the characteristics of the North Division edition of the textbook. North Division version of the materials on the handling of the contents of the function more attention to students' cognitive development law, pay more attention to the way students learn, pay more attention to the way teachers teach more attention to the cultural value of mathematics. Further strengthen the function ideological penetration, to strengthen the function and related disciplines as well as real life contact, mathematics teaching should continue to pursue the goal to strengthen the role of computer technology in the learning function.
