A Comparative Study On The Contents Of The Sequence Of High School Mathematics Textbook

The Jiangsu Education Press has been widely used in Jiangsu and other areas for more than ten years.During this period,its practical value and research value have been fully reflected.However,with the reform of Jiangsu College Entrance Examination,many places have begun to gradually promote the use of PEP 2019 A textbook,which is a challenge for teachers who are used to using the textbook for many years.Therefore,it is necessary to compare the two press of textbooks.In this thesis,we take the sequence content of senior high school mathematics textbooks published by Jiangsu Education Press and People's education 2019 A Press as the research object.By using the methods of literature analysis,comparative research and content analysis,we analyze the two modules of content and examples(exercises)from frame structure,knowledge content,presentation mode and difficulty of examples(exercises)with the research model of comprehensive difficulty of exercises.And we can have the following conclusions from the comparison and analysis of the sequence contents of the two press.The difference of the frame structure of the two press textbooks is that the PEP emphasizes the relationship between the general formula of the sequence and the first N-term sum formula.The guidance of the PEP is more pertinent than JEP,and other aspects are similar.The chapter introduction of JEP is closer to real life,and the way to present knowledge points is more direct.The number of columns is relatively few,and it pays attention to the use of information technology to solve the problem of sequence.The chapter summary mainly include the overview and knowledge listing of this chapter.The number of exercises is richer than PEP.Meanwhile,the exercises' requirements of operation are higher,and its comprehensive difficulty is slightly lower.The chapter introduction of PEP focuses on revealing the structure of knowledge and infiltrating mathematics core competences.The presentation of knowledge points tend to be gradual.This presentation highlight the generation and evolution of knowledge,which is in line with the laws of students'cognitive development.There are a large number of columns in PEP.PEP focuses on leading the classroom with questions by thinking and exploration columns and question mark annotations,and it also pays attention to infiltrating mathematics history and mathematics culture through reading columns.The chapter summary focuses on students'reflection,among which structure diagram pays more attention to the connection between knowledge.Examples (Exercises)have high level in operation and reasoning factors.Meanwhile,its situation of the topic is abundant,and the comprehensive difficulty is slightly high.In view of the above conclusions,this thesis puts forward some suggestions for the use of People's Education 2019 A Press:(1)Grasp the actual background of the concept;(2)Make good use of the question in the textbook,and cultivate students' question consciousness;(3)Make good use of characteristic column,and infiltrate mathematics core competences;(4)Use examples and exercises reasonably.Teachers should arrange the exercises in different levels to meet the needs of personalized development.
