A Comparative Study On The New And Old Textbooks Of Senior Middle School Mathematics Teaching By People

“Mathematics curriculum standards for ordinary high schools(2017edition)”officially put forward six major mathematics core literacy,mathematics teaching material is the concrete materialization of mathematics curriculum standards,is an important grasp and resources to implement mathematics curriculum standards,the compilation of teaching materials has a direct impact on the students' “Learning opportunity”and the attainment of their core literacy,so it becomes an important task of the High School Mathematics Curriculum reform to compile teaching materials with the characteristics of cultivating students' core literacy of mathematics subject.At present,the 2019 version of the senior high school math people's education a version of the textbook has gradually been used throughout the country,so what are the features of the new textbooks? Can Teachers really understand the intention of the textbook in the process of using it? These are all worthy of our study.Function is the most basic concept of modern mathematics,its concept has always been at the core of mathematics,“Ordinary high school mathematics curriculum standards(2017 edition)”will function content set as one of the four main lines,among them,the orientation,selection and arrangement of the function content have also changed greatly in the course of textbook revision,which has strong research value.Therefore,this research chooses the 2007 edition and 2019 edition of Senior High School Mathematics teaching a version of the functional content of the textbook as a comparative study object.Using the method of literature study,Content analysis and comparative study,we first compare the changes of the corresponding curriculum standards of the new and old textbooks,and on this basis,we compare the part contents of the function of the new and old textbooks with the macro and micro dimensions,the characteristics of the new textbook are as follows: It embodies the “Learning material view”based on students' development,emphasizes the whole teaching view,adopts the main-line course structure,improves the style structure,and studies the knowledge arrangement Focus on the function and the actual link in life.On this basis,the first-line teachers interview to further understand the use of new teaching materials,and from the perspective of teachers to understand how to better use of teaching materials.Based on the results of the comparison between the old and the new textbooks and the teachers' interviews,the teaching suggestions are put forward: Paying attention to the connection of the functional knowledge between the junior and senior middle schools;It is good at leading students to sum up the basic thinking of studying function,connecting the related contents with the viewpoint of function,cultivating the students' holistic view of mathematics,attaching importance to the value of background and application,developing the students' mathematical modeling attainments;Pay attention to study the concrete function with the aid of information technology tool.
