A Comparative Study Of The Compulsory Part Of The Functions Of The New And Old Textbooks Of The People's Education A Version

Functions and their thoughts run through the mathematics content of the entire high school stage,and also have a wide range of applications in real life,its importance is self-evident.This article is based on the "General High School Mathematics Curriculum Standards(Experiment)" under the guidance of the People's Education A version of the general high school curriculum standard experimental textbook "Mathematics" and the "General High School Mathematics Curriculum Standards(2017 Edition)" under the guidance of the People's Education A version of the general high school textbook The compulsory part of functions in "Mathematics" is the research object,using literature analysis,comparison,investigation and statistical analysis andother research methods to specifically study the following three questions:Question 1: What are the changes in the "Textbook 2019 Edition" compared to the "Textbook 2007 Edition"?Question 2: What are the characteristics of the "2019 Edition Textbook"?Question 3: Are teachers and students satisfied with the "2019 Edition Textbook"? What should be paid attention to in the teaching of "Textbook 2019Edition"?The main results and conclusions of the research are:(1)Comparison of the two editions of teaching materials The content of the function is based on the comparison of the writing concept,writing goals,and content requirements of the "2017 Curriculum Standard" and the "2003 Curriculum Standard" from the five dimensions of organizational structure,material selection,presentation style,course difficulty,and integration with information technology.The compulsory content of the textbook function of the edition is compared,and the comparison of presentation style is carried out from four aspects: layout design,chapter introduction,column design,and chapter summary.By comparing the two editions of textbooks,the following main conclusions are drawn:(1)The arrangement sequence of the "2019 Edition Textbook" is more in line with students' cognitive laws,step by step,and more highlights the inherent logic of mathematical knowledge.The "2019 Edition Textbook" compiles mathematical modeling into a separate section to allow teachers to focus on students' mathematics Cultivation and development of modeling literacy;(2)The materials of "Textbook of 2019 Edition" are more abundant than thoseof "Textbook of 2007 Edition",closely following the development of society;(3)The pictures of the "2019 Edition Textbook" have become colorful,and the number of tables and images are more than those of the "2007 Edition Textbook".The language expression of the chapter preface and chapter summaryis more friendly and guiding,and an "induction" column has been added.;(4)Compared with the 2007 version of the textbook,the content of the "2019Edition Textbook" has increased,but the class hours have been reduced and the difficulty has increased;(5)"The Textbook of the 2019 Edition" uses more information technology than the "Textbook of the 2007 Edition",and the use of software is more in line with the development trend of science and technology.(2)Survey of satisfaction with the use of "Textbook 2019 Edition"(1)Most teachers are very concerned about the order and logic of the content arrangement in the textbooks,so more teachers like the arrangement order of the new textbooks;(2)Most teachers and students prefer the setting form of each column in the new textbook,which is more conducive to students' self-study;(3)In order to meet the requirements of the college entrance examination,most teachers report that the teaching tasks are heavy;(4)It is difficult to implement the part of the new textbooks that integrate with information technology.On the one hand,the class hours are tight,on the other hand,the school's facilities and equipment are incomplete,and some teachers are not proficient in the use of information technology.(3)Features of "Textbook 2019 Edition"(1)Sequence;(2)Cohesion;(3)Affinity;(4)Life;(5)Problem;(6)Quality.(4)Suggestions1)Suggestions for teacher teaching:(1)Problem-guided teaching;(2)Pay attention to pre-class preview;(3)Pay attention to induction and summary;(4)Use variant training;(5)Emphasize reflection and transfer;(6)Proficiency in teaching software.2)Suggestions for textbook compilation:(1)The content of the textbook should be scientific;(2)The content arrangement should be "consistent in teaching and testing".
