| Under the background of the new curriculum reform,due to the differences in the positioning,guiding ideology and writing style of textbooks,there are great differences in the writing form of textbooks.Although all versions of textbooks are written in accordance with the requirements of the curriculum standard,But different textbooks are different in many aspects,such as the arrangement of content order,the integration of mathematical culture,the configuration of exercises,the presentation of concepts,and the setting of exploration activities.More and more teachers will conduct integrated teaching by comparing and analyzing different teaching materials.Firstly,this paper makes a statistical study of the contents of the three fields of "number and Algebra","Graphics and geometry" and "probability and statistics" in the textbooks of Chinese Mathematics Education Edition(2012 edition)and Beijing Normal University Edition(2012 edition)in the four aspects of chapter arrangement order,concept presentation,mathematical history and the setting of exploration activities.Through the comparative study of the contents of the two editions of the textbook,the following conclusions are drawn: In terms of the arrangement order of chapter contents,the textbook of the Humanities edition tends to thoroughly study the knowledge of a certain section in a period of time,so it presents a strong integrity in the arrangement of content,while the textbook of Beijing Normal University presents a spiral structure.A section of knowledge will be divided into two or more parts distributed in three different grades,the amount of class time than the human edition;In terms of the infiltration of mathematical history,the Humanities Edition incorporates different types of mathematical history in the three fields with a moderate amount of integration,while the North Normal Edition incorporates a small amount of integration,but most of them appear in the form of short stories,with a strong sense of integration.In terms of the presentation of concepts,the number of inquisitive concepts in the human Education edition is small,while the Beijing Normal University edition has more inquisitive concepts in the field of probability and statistics,which is beneficial for teachers to carry out exploration activities and let students know a certain concept in mutual communication.From the setting of inquiry activities,the inquiry activities of the Edition are generally mathematical,rigorous and serious.These activities require students to have keen observation ability and good hands-on ability.However,there are many inquiry activities in Beijing Normal University edition,and teachers can also perceive the teaching orientation from these inquiry activities.However,a considerable part of the inquiry activities in the textbooks do not have specific forms and contents of inquiry,but are driven by some questions that are difficult for students to understand.Secondly,from the perspective of improving classroom efficiency,this paper makes a horizontal comparative analysis of the two editions of the textbook,the overall analysis of the characteristics of the two editions of the textbook.The content of the human education edition is more suitable for students with general foundation.The content of the textbook of Beijing Normal University is more suitable for students with flexible thinking and extreme love for mathematics.In actual teaching,teachers should integrate more mathematical culture to broaden students’ mathematical vision.Finally,combined with the conclusion of the above comparative research,some feasible suggestions are put forward for teachers to analyze the teaching materials :(1)unit analysis,grasp the logic,clarify the thinking;(2)The teaching method of partial deliberation,index induction and deduction,using these two methods to design the teaching program of the nature and judgment of the square in the human education edition and the exploration of the Pythagorean Theorem in Beijing Normal University edition. |
