The Application Of Graphic Calculator In High School Mathematics Function Teaching

In order to implement the requirements of the 18 th and 19 th National Congress of the Communist Party of China on morality and talent cultivation,and further deepen the curriculum reform of basic education,the Ministry of Education issued the2017 edition of mathematics curriculum standards for ordinary senior high schools.According to the new curriculum standard,attention should be paid to the integration of information technology and mathematics curriculum.The basic principle of integration is to help students understand the essence of mathematics.With the rapid development of science and technology and the development of mathematics itself,education has put forward higher requirements for mathematics.Mathematics has gone from behind the scenes to the stage,directly creating value for the society.In this context,it is necessary to enter the high school mathematics classroom,and the graphic calculator is very consistent with this theme.With the help of graphic calculator to improve the teaching effect has become the consensus of most mathematics teachers,how to better apply the graphic calculator to mathematics teaching has become a hot topic of discussion among teachers.Function is an important part of high school mathematics curriculum,its basic idea runs through the whole high school mathematics course,and even affects the whole mathematics learning career.However,due to the abstract nature of functions,students are more difficult to learn,but also teachers agree that teaching is important and difficult.Therefore,improving the teaching effect of function is the difficulty that teachers want to overcome.This paper discusses the high school mathematics function teaching based on the graphic calculator.Through the relevant practical research,it proves the positive role of the graphic calculator in improving the effectiveness of the function teaching,analyzes the current situation of the graphic calculator involved in the mathematics classroom,and puts forward improvement strategies for the existing problems,so as to accumulate experience for the promotion of the graphic calculator in high school function teaching in the future Learning,teaching and research and classroom practice teaching provide some reference and guidance value.This paper focuses on the following parts:The first part is the introduction part,first describes the research background,significance and purpose of this paper;the related concepts of graphic calculator;through literature collation and analysis,understand the research status quo of high school mathematics function teaching based on graphic calculator at home and abroad,point out the shortcomings of existing research,and point out the research methods of this paper.The second part is the theoretical overview,which defines the concept of graphic calculator,function and teaching effectiveness;expounds the important position of function in the whole senior high school mathematics;the role of graphic calculator in high school mathematics function teaching and the function course content suitable for teaching with graphic calculator;the influence on current "Teaching and learning";the principle of integrating with mathematics curriculum;the principle of function teaching;Finally,this paper expounds the theoretical basis of this paper,constructivism learning theory and discovery teaching theory.The third part is the practical research.This paper will take the first grade students of a key middle school in Taiyuan city of Shanxi Province as the research object.Through the comparison in two classes of the same type,the positive role of the graphic calculator in the function teaching effect is confirmed.Secondly,through the form of questionnaires and interviews with students and teachers,according to the analysis of the survey data and the summary of the interview results,we can understand the use of the graphic calculator and the comparison of the learning effect before and after the use of the function,and find out the application status and problems of the graphic calculator in high school function teaching.The fourth part is the improvement strategy,aiming at the problems found in the practical application of graphic calculator in high school function teaching,puts forward the corresponding improvement strategy.Due to the limitation of equipment,with the popularization of science and technology,graphic calculators will be more affordable;teachers should update teaching concepts and teaching models,improveteaching methods,increase the emphasis on graphic calculators,strengthen the ability to skillfully operate new technologies,and follow the principles of using graphic calculators;schools and other relevant departments should organize more training related to graphic calculators and carry out more graphic calculators Computer related experimental skills competition,improvement of evaluation methods,etc.In view of the present situation,this paper puts forward some ideas on the application of graphic calculator in mathematics teaching,and provides some feasible suggestions and operations for optimizing function teaching.The fifth part is teaching practice.It gives two cases of function teaching with the help of graphic calculator,and describes the teaching mode of function teaching under graphic calculator.In order to provide some reference opinions for the future front-line teachers to teach these two classes.The sixth part is the conclusion of the study,which expounds the status and role of this research work in the field of mathematics teaching,the experience accumulation in the research process,the problems to be solved and the lack of research in this paper.
