Research On The Use Of Plane Analytical Geometry Parts Of The Mathematics Textbooks Used In Senior High Schools Under The Requirement Of New Mathematics Curriculum Standard

In 2018,eight provinces or municipalities such as Hunan and Chongqing started the comprehensive reform of the college entrance examination,which began to be implemented from the first grade students who entered the senior high school in the autumn of 2018.However,the new high school mathematics textbooks adapted to the new mathematics curriculum standard and the new college entrance examination have not yet been published.The first grade students who entered the senior high school in the autumn of 2018 of these provinces or municipalities still need to use existing old mathematics textbooks.For example,many schools in Hunan and Chongqing use the mathematics textbooks(A edition of PEP).Plane analytical geometry is an important part of high school mathematics,and the value of educating students is very high.It is of great significance to teach this part well.Does it meet the new requirements of the new mathematics curriculum standard to teach plane analytical geometry using the mathematics textbooks(A edition of PEP)? How to use to adapt to the requirements of the new mathematics curriculum standards? These issues need to be resolved.The purpose of this article is to answer these questions.In this paper,I used the literature method,content analysis method,comparative research method and investigation method to carry out research,clarified the new requirements of the new mathematics curriculum standard for the plane analytic geometry teaching,and analyzed the content of the plane analytic geometry parts of the mathematics textbooks(A edition of PEP).Analysis,interviews and questionnaires were conducted on the status of its use.The main body of the article is divided into four parts.In the first part,I analyzed the new requirements of the new mathematics curriculum standard for the teaching of planar analytical geometry from the five aspects of goal,content,structure,teaching and evaluation.In the second part,the plane analytic geometry parts of the mathematics textbooks(A edition of PEP)were analyzed from four aspects: the main knowledge points,the mathematical thoughts,the integration of teaching content and information technology,and the points used to improve the core literacy of students in mathematics in textbooks.In the third part,in order to clarify the current situation of the use of the analytic geometry parts of the mathematics textbooks(A edition of PEP),the textbooks adoption and teaching sequence were analyzed,and interviews and questionnaires were conducted on the specific use of the textbooks of teachers and students.The fourth part,based on the content and application status of plane analytic geometry parts in the mathematics textbooks(A edition of PEP),in order to meet the new requirements of the new mathematics curriculum standard for plane analytic geometry teaching,I gived the teachers —who teach plane analytic geometry using the mathematics textbooks(A edition of PEP),and facing the comprehensive reform of college entrance examination —some suggestions from seven aspects: selection of textbooks for conic curve and equation,teaching order,selection of knowledge points in textbooks,the use of mathematics academic quality standard,understanding of mathematical ideas,integration with information technology,and methods to improve students' core literacy in mathematics subject.The results and conclusions of the research are as follows: the new mathematics curriculum standard puted forward new requirements for the teaching of plane analytic geometry;under the background of the new mathematics curriculum standard and the new college entrance examination,the compulsory course 2 and the optional course 1-1 of PEP can be used to carry out plane analytic geometry teaching,but there are some shortcomings in these two textbooks,which need to be remedied by teachers in teaching.At the same time,mathematics teachers in senior high schools should also improve their information technology level.They should pay more attention to the role of textbooks in teaching and make good use of them.
