A Comparative Study Of Plane Analytic Geometry Of High School Mathematics Textbooks

In a new round of teaching reform,each edition of the textbook is ready for a new round of revision with the promulgations of the ministry of education's opinions on the basic task of the implementation of the curriculum reform and the "Core literacy of Chinese students"(draft for comments).As one of the core contents of mathematics teaching in high school,plane analytic geometry has important research value.In order to better grasp the contents of plane analytic geometry in the textbook,this study is to compare the contents of plane analytic geometry in the textbook by the five editions of textbooks published by People education publishing house(PEP),Beijing normal university press(BNUP),Hunan education publishing house(HEP)and Jiangsu education publishing house(JSP).This study compares the two main dimensions of the system content and knowledge presentation of the teaching materials,and discusses the mathematical core qualities of the teaching materials,and obtains the following conclusions:1.The similarity of textbooks in the "plane analytic geometry" section.(1)The overall arrangement of the contents of the teaching materials is consistent,and the amount of class hours is basically the same.(2)The equation of the circle,the rectangular coordinate system of space,the establishment of the conic curve equation and the commonality of the geometric properties.(3)In the way of knowledge presentation,each version of the textbook attaches importance to the diversification of knowledge presentation,so as to arouse students' interest in learning.2.The differences of the textbook materials in the "plane analytic geometry" section.(1)There are different ways of thinking.(2)The different teaching materials have different emphasis on specific knowledge,and there are large differences in the linear equation.(3)The different teaching materials show different degree of knowledge and different emphasis on plane analytic geometry.(4)The differences in the specific knowledge points of the textbook reflect the different requirements of the teaching materials on the core quality of mathematics.(5)The teaching materials are designed differently,and the level of knowledge presentation is different,and the attraction to students is different.The PEPA version is better,and the other versions have their own advantages and disadvantages.(6)The different column Settings show that different versions of textbooks have different emphasis on the cultivation of students' abilities.The number of BNUP is the most,the HEP version is the most characteristic.(7)The math problems can detect the learning effect of students' stages and enrich their knowledge.The math problems of the JSP version are best set,and the rest are good and bad.By comparing and analyzing the conclusion,we get the features of the geometry content of the five editions of the textbook,and some Suggestions are put forward.
