A Comparative Study Of Junior High School Mathematics Textbooks Function Contents

Content:Since the start of the new round of curriculum reform,the region began the trial of each new version of the textbook,which areas of Shandong Province,Qingdao Publishing House(hereinafter referred to Qingdao version)junior high school mathematics textbooks,this version of the texebook use shorterand a smaller range, where the gaps in order to understand the preparation of Qingdao texebooks and other editions of texebooks,Qingdao Publishing House of the junior high school mathematics textbooks nationwide use of the widest range of people’s Education Publishing House(herinafter referred to PEP) textbook comparative study and research scoping part of the function, which is due to the content of the function occupies a very important position in the junior high school mathematics curriculum, but also the focus and difficulty of the junior high school mathematics teaching and learning, I hope to be able to this study was to explor Qingdao edition textbooks innovation and merit, and by comparing a gap PEP textbooks provide some help for the future continued reform of textbooks and teachers teaching.A comparative study of the contents of the function, from the macro and micro in both directions for more than two versions of the junior high school mathematics textbooks. On the macro level,this paper compare two versions of textbooks from five areas,it is respectively the course content and the grade of the teaching materials and the setting of examples and exercises and the infiltration of mathematics cultural and the integration of information technology,on the micro level,this paper compare two versions of textbooks from two areas,it is respectively the introduction of the function concept and the image processing of function,with the following conclusions:Macroscopically,(1) PEP textbook the function content arrangement more reasonable, clear framework, before and after the order of arrangement is appropriate, relative, Qingdao Version fragmented arrangement, all of the important knowledge to explain the arrangement in the ninth grade, a little top-heavy,is not conducive to effective learning, needs to be improved in this regard;(2) the selection and presentation of the function content knowledge, PEP with more emphasis on the law of development of students’ cognitive knowledge point, select detailed and reasonable presentation alsomeet the students’ cognitive law, Qingdao version somewhat lacking, attention should be improved;(3) in the case exercises set, Qingdao version number of cases of exercises set more than PEP, in the examples of problem situations settings and the difficulty of the exercisesfactors, the two versions of some difference, the main subject of the students’ personal lives are the PEP examples involving more than Qingdao version, the PEP exercises in the calculation and explore the extent higher than Qingdao version, Qingdao edition of Exercise on the knowledge contentin PEP;(4) in the mathematical and cultural infiltration, PEP is more emphasis on math and cultural infiltration, through the introduction of the history of mathematics and introductory function setting allows the students to understand the function from multiple perspectives, and Qingdao version is missingintroduction of the history of mathematics knowledge should increase in multi-angle material to penetrate the mathematical culture, develop students’ mathematical perception;(5) IT integration, the PEP select material Qingdao version, with more emphasis on teaching materials and informationthe integration of technology, Qingdao how easy it some effort.In microcosmic,(1) on the introduction of the concept of function, the example cited by the PEP function concept formation material selected richer, the example analysis clearer direction, the function concept formation process more clear and compact, and formation of the concept of function the Qingdao version twoemphasis on the correspondence between the variables, ninth grade the next volume of the second concept is given only to students is not conducive to the formation of the overall construction of the concept of function;(2) in the function image processing, Qingdao version more consideration to the junior high school studentsthe cognitive development of the law, before learning function image, by setting a preliminary understanding of the function so that students first image of the function with the intuitive feelings, specific learning, more in line with students’ cognitive law.With the corresponding results,last chapter of this paper provide some thinking and recommendations,for written function content of the mathematics textbooks for the junior high school:(1)the order and interval of the content arrangement should be reasonable;(2)the drawn of problem situations should be more diversify,focusing on situations close to the student real life and strengthen links with other disciplines;(3)hierarchical set homework,lay stress on the suit of exercise and teaching important points;(4)aside spaces for students to raised problems;(5)multi-angle penetration mathematical culture;(6)strengthen the connection with IT.Mathematics textbooks of the two versions of the PEP and Qingdao version of the Comparative Study of the function of the content of the two versions of textbook materials and local materials belong are able to play some inspiration and reference, hope to junior high school mathematics teacherthe design and teaching of the content of the function to provide a reference, but because of the limited research time, there is no way understanding of Shandong Province Qingdao textbooks teaching characteristics, there is no way to give more in line with the proposals for reform of the local characteristics,this study is regret at. There are still many deficiencies need to be further improved, this study only willing to play some inspiration and reference to our middle school mathematics curriculum reform and development and textbooks...
