A Comparative Study On Circle Section Of Junior Middle School Mathematics Textbooks Published By Peoples Education Press And Beijing Normal University Press

After 1993,guided by the "Curriculum Standards(2011)",the textbook editions of the nine-year compulsory education stage in my country showed a diversified trend.Each version of the textbook has its own advantages and disadvantages,but also has its own uniqueness.Among them,the textbooks published by People's Education Press and Beijing Normal University Press are the most representative.Therefore,teachers can learn from the good points of each version of the textbooks to improve the effectiveness of teaching mathematics.This article mainly uses literature research,comparative analysis and statistical analysis methods,and mainly examines the following similarities and differences in the compilation of the teaching content of the circle chapter in the Beijing Normal University version and the People's Education version of the junior high school mathematics textbook,and draws conclusions.:1.In the layout of teaching materials,both have a complete structural system framework in the layout system,and the specific knowledge points are detailed;the People's Education Edition focuses on the internal connection between the knowledge points,and the Beijing Normal University version sets more students to explore Links;2.In terms of material configuration,the Beijing Normal University version is more inclined to decorative illustrations,while the PEP version is equipped with more life-like illustrations,and will be accompanied by text explanations;3.In the content of the exercises,The People's Education version has fewer exercises,based on allowing students to understand and master basic knowledge;the Beijing Normal University version has more exercises,and has a relatively large number of exploration and innovation exercises.4.In terms of difficulty,the Beijing Normal University version,people The content breadth of the textbook for teaching edition is 37 and 40,the content depth is 35 and 32 respectively,the comprehensive difficulty of exercises is 148.2 and 132.8,and the comprehensive difficulty value of the textbook is 7.55 and 6.96 respectively.The teaching material of Beijing Normal University is about 1.1 times more difficult than the teaching material of People's Education.After comparative analysis,this article draws the following suggestions: 1.Textbook editors should pay attention to the internal connection between the knowledge points about circles,and the development of the content should conform to the students' cognitive laws.2.When setting the types of textbook exercises,both versions of the textbooks can appropriately increase the proportion of objective questions such as multiple-choice questions and fill-in-the-blank questions;increase practical inquiry questions as appropriate.The setting of exercises should be hierarchical,and the difficulty gradually increases.3.Give teachers more teaching space,so as to adjust the time for students to study independently according to the students' specific academic conditions,so as to ensure that students have enough room for thinking.4.Teachers can appropriately adjust the teaching content and sequence according to the content of the textbook and the actual learning situation of the students,and add some life-related,interesting,and open-exploring exercises related to the circle.
