A Comparative Study On The Multiplication And Division Of Integrals And Factorization In Junior High School Mathematics Textbooks

With the comprehensive advancement of the new mathematics curriculum reform,textbooks as a carrier of the curriculum have an important role for the teaching of teachers and students 'learning.Since the new curriculum reform,in order to meet the educational needs of various regions,China encourages relevant departments to follow the new curriculum Standard guidelines are used to compile appropriate textbooks.Under the principle of "one outline,multiple books",multiple sets of textbooks have appeared throughout the country.Each version of the textbook has its own flash point.Of course,there are also shortcomings.They all differ in different ways.The form reflects the basic concept of the new curriculum standard.The development of textbooks should promote the advantages and eliminate the shortcomings.Therefore,it is necessary to compare the versions of the textbooks to find out their strengths and weaknesses,and provide some basis for the compilation of textbooks.The important content plays a role of inheritance,multiplication and division of integers and factorization is also a stepping stone for learning integers.This article selects the integral multiplication and division and factorization parts of the junior middle school mathematics textbooks of the widely used "Beijing Normal University Press" and "People's Education Press",how are the two sets of textbooks written about it? What are the advantages and disadvantages of each? This has to be an important issue that we should be concerned about.Because of this,this article attempts to conduct an in-depth and detailed comparative study of the two versions of mathematics textbooks.On the basis of absorbing the research results of others,this article conducts research and comparison on the integral multiplication and division and factorization of the two versions of the mathematics textbooks from the macro and micro levels.The macro level mainly compares the overall structure,content and arrangement order.The micro level mainly analyzes from the front of the chapter,mathematics activities,column settings,the number of example questions and the problem solving process,the number of types of exercises and the background,etc.,and finds out how the two versions of the textbook are different through comparison.Advantages and disadvantages,the research results show that the two versions of the textbook have the following advantages and disadvantages:The advantages of the Beijing Normal University version of the textbook: the textbook focuses on the student's subjectivity;the setting of example exercises is rich and vivid,and the level is clear;it is helpful for the improvement of the teaching ability of the teacher;the learning goals in the figure before the chapter explain the main content of this unit.The advantages of People's Education press textbook : the textbooks are systematically organized,and the classification and induction of knowledge points are clear;it is helpful for students to self-learn;the emphasis is on the connection of knowledge.The textbooks published by Beijing Normal University publishing house are inadequate: the examples are not detailed enough;the exercises are set in accordance with the order of the contents of the textbooks,which is not conducive to the systematic use of knowledge by students.Insufficient textbooks published by People's Education publishing house: the density of knowledge points is high;the number and types of example questions are small and not comprehensive;the difficulty of exercises is large,and the gradient of difficulty is not obvious.Provide suggestions for textbook compilation and teacher teaching according to the research results:Provide the following suggestions for textbook compilation:(1)the connection of balanced knowledge in the compilation of textbooks;(2)the combination of teacher leadership and student body;(3)the penetration of mathematics culture and the addition of more reading materials;(4)clarity Learning objectives and major and difficult points;(5)Improve the setting of example questions and pay attention to the application of knowledge;(6)Pay attention to the diversity of exercises and train students to develop comprehensively.Provide the following suggestions for teachers 'teaching:(1)Teachers should conduct textbook research and fully understand the textbooks;(2)Teachers should understand the textbooks of various versions and improve instructional design;(3)Teachers should understand students,use teaching materials creatively,and choose appropriate Teaching methods,targeted teaching;(4)Life long learning,and strive to improve itself.
