The Comparative Of Circle And Similar Graphics In Junior Middle School Mathematics Textbooks Between China And Japan

Teaching material is not only an important tool for teachers to launch teaching activities,but also a excellent teacher and helpful friend for students.Researching materials can be used to talk with the writers of the teaching materials,feel the intention of the writer and determine the correct teaching objectives.Study chooses ZEP mathematics textbook and Japanese mathematics textbooks of digital research as the object of research,by Literature,content analysis and comparative study,circular and similar graphics as a case study.Unfolding research from the specific comparison,specific objective comparison includes the macro and micro comparison studies and difficulty of exercises study.The following conclusions are drawn:From the geometry of the whole,the two countries have the same attention on Mathematics Teaching in graphics and geometry,and Chinese textbook is divided more detailed content in geometry,and the level of knowledge is more extensive;in the order of arrangement,the Chinese textbook is more logical than the Japanese textbook,and it introduces the detailed knowledge of geometry content,while Japan the textbook is slightly scattered.In terms of knowledge background,Chinese textbooks are more diverse and emphasize the process of students' study.However,the theoretical thinking level of Chinese textbooks is lower than Japanese textbooks,which requires students to analyze and judge more active.it has higher requirements for students' abstract ability.Japanese textbooks lay stress on the students' ability to apply knowledge.On the comprehensive difficulty of the exercises,The total number of Chinese exercises and type of exercises far more than the Japanese textbooks,their background is very rich,and the topic of operating memory level significantly more than the Japanese textbooks.On the basis of the conclusions of research,the following suggestions are put forward to the compilation of Chinese textbooks:(1)The writing of the textbook should be based on the students,and a rich background should be selected to enhance the readability of the textbook.(2)The compilation of teaching materials should be advocated to allow students to understand and experience,build a bridge between old and new knowledge and increase the proportion of cognitive problems.(3)Enriching the type and background of the exercises can stimulate the students' learning motivation.
