| It is the most important content for curriculum reform of basic education to exploit and utilize the curriculum resource.The teaching material is the material carrier of the course, it has an important reference and guidance for the formation of student’s knowledge structure and teacher’s teaching process.This paper chooses textbooks published by People Education Press,by Beijing Normal University and by Jiangsu Education Press as research carrier and carries out research work from the two aspects of the overall analysis and the concrete analysis of the teaching material.This paper makes an in-depth study on the methods of literature analysis,statistical analysis and content analysis, such as the introduction of the teaching materials, the design of the columns, the exercises of the questions, the introduction and presentation of the function concepts, the image properties of the functions and the infiltration of the mathematical methods.The study is divided into three parts. The first part is the introduction and the research summary, mainly introduces the research background, the research significance, the research method as well as from the foreign and the domestic two aspects summarizes the current research present situation; The second part is from the overall aspect and the specific aspect make an analysis and evaluation for the three Version of the textbook , which is the main part of this article; the third part is the conclusions of the comparative study, and make recommendations.The conclusions drawn from the comparative analysis are as follows:On the whole, (I) the preparation of the system is very similar to,pre-chapter and the introduction all set before each chapter,set up a rich section,the body content export from the activity section,present the basics,and then through examples and the exercises to practice and feedback; and then a number of sections constitute a chapter, at the end of the chapter have summary; (2) column design is very rich, such as the Beijing Normal University division with "do", "think", "try"; People Education division with "thinking", "inquiry", "induction", "reading and thinking", "the use of information technology" and other columns; Jiangsu Education division with"thinking", "communication", "analysis", "induction", "reading", "discussion" and other columns. (3) On the arrangement of linear function,three versions of the textbooks show a big difference.The editions published by People Education Press and by Jiangsu Eduction Press have been arranged in one chapter, introduced into the function image, and then to the function and equation, inequality and function of the application.However,the edition published by Beijing Normal University Press have been arranged related knowledge from Grade 7 to Grade 8,focusing on the early penetration of the concept, and penetrate knowledge throughout the junior high school algebra teaching, becoming a main line through the algebra. (4) In the exercises,the editions published by People Education Press and by Beijing Normal University Press have been arranged rich background knowledge, at the same time the type of problem is rich. While the problem number of edition published by Jiangsu Education Press is moderate, but the type is too single,the main type is short answer , lack of operation,discussion, open exercises which can train students’ active participation and enthusiasm.In the specific content, (1) When introduce the concept of function, the three versions all choose the subject of learning topics which are familiar to students, the introduction of knowledge in the teaching process, the problem which raised and resolved all in a certain situation, paying attention to the source of mathematics and applications. (2) In the image and nature of the function,the three versions all take the student as the center, focusing on changes in student learning. The way to explain the knowledge points is operation, independent exploration instead of straightforward results or conclusions. (3) In the penetrating. of mathematical thinking,the three versions are particularly emphasized the importance of learning mathematical thinking, having infiltrated mathematical thinking such as induction,analogy,combination of number and graph, classification and induction, equations and other mathematical ideas, in which "combination of number and graph" is the most important thought.Finally, after conclusion, this paper has carried on the reflection to the writing material of junior middle school mathematics function content and made some suggestions.The researchpossibly provides reference not only to the preparation and amendment of junior middle school mathematics textbook, but also to teachers who carry on instructional designs.But there are still some shortcomings which need further improvement. |
