A Study On The Characteristics Of Spiral Compilation Of Mathematics Textbook Contents

Mathematics textbook is the main carrier of mathematics knowledge system and the resource to promote the development and progress of mathematics.It is of great value to the research of mathematics teaching material.In the process of learning graphics movement,teaching materials play a very important role.The requirements of curriculum standards are materialized in teaching materials,and affect students' learning results through teachers' teaching and students' learning.Therefore,the study of the movement content arrangement of graphics plays an important role.This paper adopts the methods of literature,comparative research,content analysis,qualitative research and quantitative analysis,and makes a spiral arrangement of the movement content of the mathematics teaching materials in the compulsory education stage of the Soviet education edition,the people's education edition and the Beijing normal University edition.The research is carried out from four aspects: spiral interval,content breadth,content depth and difficulty of exercises.Through comparative analysis,the following conclusions and recommendations are obtained:The main conclusions are as follows: the number of spirals and the average time interval between the three versions of textbooks are different,and the time interval of the same school period is shorter than that of different school periods.In terms of content breadth,all three versions of the textbook cover axisymmetric,translation,rotation and applications in other fields of Graph and Geometry,but the number of knowledge points covered in each segment is different.The main reason for this difference is that the combination of knowledge points in each class is different.In terms of content depth,the introduction of the concepts of translation,rotation and axisymmetric graphics,description and application in the writing characteristics of teaching materials in three sections,translation properties 1,rotating The discovery of property 2 and axisymmetric property 3 proves and applies the characteristics of textbook writing in the second and third classes,which are basically written in the order of visual level-analysis level-informal deduction level.With the rise of the school section,the requirements for students' thinking level are also improving,and the contents of the teaching materials are arranged spirally.Exercises all pay attention to the importance of practice to the acquisition of knowledge and the cultivation of ability,but in the difficulty of exercises,the three versions are different in different segments and are basically arranged spirally.Suggestions are put forward for the compilation of each version of teaching materials: 1.In the teaching activities,teachers should make rational use of the appreciation and design of patterns to better arouse students' interest in learning and improve classroom efficiency.2.In the people's Education Edition,it is suggested that the units and class hours of the class should be increased,the distance between the old and the new knowledge should be narrowed,and the relationship between knowledge and knowledge should be communicated step by step.3,Beijing normal University edition,should add some interesting pattern appreciation plate,make the textbook more full of lively breath in life.4,put forward suggestions for teaching.
