A Comparative Study On Plane Vector And Its Application Between New And Old Textbooks A Senior Middle School

The foundation of education lies in moral casting soul." foster character and civic virtue" is the basic task of education,and teachers of new era of responsibility and mission,deepen the reform of education and the classroom is the main position,want to build people-oriented,during the qualitative good classroom ecology,to improve teachers' ability to use the teaching material,of the educational value of reading and found that the teaching material,in main land to carry out the classroom ecosystem.Under the background of mathematics core literacy,it is urgent to solve the problems of how to interpret the new high school mathematics textbooks and how to use them scientifically and normatively.This paper takes "A comparative study of the plane vector and its application in the new and old textbooks of Senior high School Mathematics Teaching A" as the research topic,and takes "plane vector and its application" as the research object,through content analysis method,quantitative analysis method,comparative research method and other research methods.The main problems of this paper are as follows:(1)What are the changes of "chapter structure" of plane vector and its application in the two editions of textbooks?(2)What are the changes in the "textbook content" of plane vector and its application in the two editions?(3)What are the changes in "course difficulty" of plane vector and its application in the two editions of textbooks?This paper explains the difference of "plane vector and its application" between the new and old curriculum standard of high school mathematics from the aspects of curriculum structure,content requirements and teaching suggestions.On this basis,the author uses statistical analysis,comparative analysis,content analysis and other methods to make a comparative analysis of the new and old textbooks from the dimensions of chapter structure,textbook content,course difficulty and so on,and draws the following conclusions:(1)In terms of chapter structure,the new textbook adds "section introduction".The chapter head is concise and clearly presents the knowledge learning context of this chapter.The number of narration is greatly increased,which pays more attention to the inspiration and guidance of students' thinking and better reflects the integrity of vector learning.(2)the teaching material content,new teaching material for the plane vector operations section with the method of the centralized layout,changing the order of sine and cosine theorem,to modify the other knowledge arrangement,pay more attention to the structure of the knowledge system and logic relationship,pay more attention to penetration of mathematical culture,pay more attention to the topic number of fitment and cases of the quality of the problem.(3)In terms of course difficulty,the plane vector and its application of the new textbook are higher than the old textbook in terms of course breadth,course depth and comprehensive difficulty of example exercises.The class arrangement of the new textbook is less than the old textbook,and the course difficulty is generally higher than the old textbook.Based on the above conclusions,the author puts forward the following teaching strategies and suggestions for the content of "Plane vector and its Application" :(1)Give full play to the optimization role of chapter structure of the new textbook,inspire students to think,help students systematically sort out and summarize the knowledge of the whole chapter,and promote students to develop good math learning habits.(2)The changes of the content arrangement of the new teaching material are integrated into the teaching design,and the students' grasp of the overall content of plane vector is strengthened by the way of warm introduction,so as to reflect the teaching concept of unit.(3)Fully excavate the essence of knowledge,optimize teaching design and class hour arrangement.
