Research On "Double Line Teaching Method" Of Function Concept In Senior High School

The research on functional concept teaching in senior high school has a long history and many scholars have studied it from different perspectives.In recent years,more and more attention has been paid to the study of middle school mathematics teaching from the perspective of modern higher mathematics.At the same time,the study of integrating mathematics culture into middle school mathematics teaching has also been widely paid attention to.The study and practice of middle school mathematics teaching have gained new vitality and achieved good results.The new curriculum standard points out that teachers should guide students to grasp the essence of mathematics content,understand the structure and system of mathematics curriculum,and pay attention to the penetration of mathematics culture.Based on this,in view of the characteristics of high school function concept teaching,the author synthesizes the "high point of view" mathematics teaching concept and the teaching strategy of integrating mathematics culture,and puts forward the research topic of high school function concept "double-line teaching".High school function concept "double teaching" pay more attention to students' psychological characteristics,reduce the difficulty,the characteristics of slow slope,stimulate interest,starting from the teaching requirements of the teachers and students learning needs,to the classroom teaching and practical problems as the carrier,help teachers and students to solve the problem of function during the process of concept teaching,effectively alleviate the previous function concept teaching obscure the dilemma,More understandable and interesting.This paper first analyzes the literature to understand and sort out the research situation of function concept teaching in recent years.Secondly,the present situation of school teaching was investigated,the implementation environment of "double-line teaching" was explored,and the feasible and necessary conclusion was drawn.Then through the detailed analysis of the curriculum standards and the comparative study of the teaching materials,the teaching content and teaching level of the depth of understanding.On the basis of the completion of the preparatory work,the teaching design of the section of function concept is carried out by using the concept of "double-line teaching".Finally,the teaching effect is verified through teaching practice.The "double-line teaching" is tested through two indicators of students' interest in math learning and math test scores,and effective conclusions are drawn.At last,the research also points out the shortcomings in practice and implementation suggestions.
