Comparative Study On The "Graphics And Geometry" Textbooks Of Junior Middle School Mathematics Published By Jiangsu Education Press And People's Education Pres

Geometry has a long and colorful history and has become a major component of mathematics learning for students in China.The Compulsory Education Mathematics Curriculum Standards(2022 Edition)has structured and integrated the content of "Graphs and Geometry",and the textbooks of the Jiangsu Education Press and People’s Education Press editions will be revised on this basis.Based on the promotion and development of the standards and the importance of the section of"graphs and geometry",this paper takes the content of the third grade of compulsory education in the area of "graphs and geometry" as the carrier,and uses the methods of literature,content analysis and comparative research to conduct a study of the textbooks of both the JEP and the PEP,we use literature,content analysis,and comparative research methods to analyze the textbooks of the JEP and PEP editions in three dimensions:macro,micro,and consistency of knowledge,and obtain the following conclusions:From the macroscopic dimension,both textbooks emphasize the construction of the curriculum in the field of"graphing and geometry",but the number of chapters in the PEP version is greater,and the JEP version is more colorful.The two textbooks have a strong connection with each other and are arranged in the order of "Chapter-Section-SummaryReview Questions".The order of "Chapter-Section-Summary-Review Questions"is arranged.The sections of both sets of textbooks are reasonable,but the PEP version is richer and more distinctive.The two sets of textbooks contain basically the same knowledge content,which are arranged in the order of lines,planes,angles,triangles,parallelograms,and circles,focusing on the generation,development,and connection between knowledge.In terms of micro dimensions,the two sets of textbooks have a larger proportion of context-free examples and a smaller number of other contextual examples.The textbook of the JEP version contains a higher proportion of one knowledge point and three knowledge point examples,and the textbook of the PEP version contains a higher proportion of two knowledge point examples.The two versions of the textbook involved more exercises in the eighth and ninth grades and fewer exercises in the seventh grade,with a large proportion of calculation and short answer questions.Chapter exercises are more difficult in the JEP version of the textbook and less difficult in the PEP version,but the shortcoming of both versions of the textbook is that there is not enough background for the exercises.The illustration content in the JEP version of the textbook is larger,and both versions of the textbook are mainly mathematical illustrations,supplemented by life and fun illustrations,with less history of mathematics illustrations,and the illustrations are mostly concentrated in the eighth grade.From the perspective of consistency of knowledge,the PEP version is more natural in articulation and fits students’ existing experience,while the JEP version focuses more on the construction of the knowledge system in articulation,and the writing ideas of elementary school and junior high school are more unified and more difficult,which is challenging for students to learn.Finally,by analyzing the characteristics of different versions of textbooks,the thesis proposes suggestions for the design and preparation of the section of "Graphs and Geometry":to make a good connection between primary and junior high school textbooks;to strengthen the integration of the history of mathematics and the content of textbooks;to give students opportunities for reflection;to strengthen the integration of information technology and mathematical knowledge in the textbooks;to optimize the structure of sample problems and to enrich problem situations.Enriching problem situations.
