The Comparative Study On Teaching Material Design Of Function Concept In Senior High School

Along with the implementation of the "many textbooks on one guideline" policy in our country,the mathematics textbook which as the basic carrier that bearing teaching content and curriculum goals ended with the situation of "textbook published by people's education press" which unify the whole country,and the good situation of coexistence of various textbooks of different versions of teaching materials,different versions of the same teaching module research also become the current hot topics in the study of mathematics curriculum reform.Research literature can be found that many researchers on a comparison of high school mathematical function section,the angle of the study including the introduction of the concept,writing style,sample problem sets of configuration,situational setting,difficulty and so on,and got some comparison results.These results always focus on the advantages and disadvantages between the teaching material and then puts forward some suggestions according to the teaching material quality.However,few researchers research on the comparison the all teaching materials which under the new curriculum standard from vertical and horizontal and few researchers made improvement to the teaching material which exist some imperfections and wrote a new tutorial.In this paper first use the method of literature,comparison and statistical analysis to compare the knowledge selection and layout,the introduction of the concept of function,presentation and the selection of materials which help the students accept the concept of function among the different versions of textbooks of Function and its part.On this put forward the teaching suggestions such as put the mapped into the reading materials,desalination business concept and rewriting the textbooks with the relational theory of function.The innovation of this paper is to compile the new textbook case based on the relational theory of function.The new tutorial can be overcome the disadvantage of theory of correspondence which exist in itself and could help the students understand the function better.The new tutorial is very pay attention to the combination ofsymbolic and graphic that will be helpful for students study the follow-up knowledge.Hope the result of this paper could provide valuable reference information for the high school mathematics curriculum reform in our country.We hope our teaching material construction will be better and better and we will make greater contribution for training talents.
