Research On Function Teaching In Senior High School Based On Geogebra Cultivating Mathematics Core Literacy

With the development of science and technology,information technology provides more technical support for mathematics teaching.The deep integration of information technology and teaching is an effective way and method to change the traditional teaching method and cultivate students’ core qualities.China’s《Mathematics Curriculum Standards for Normal High Schools(2017 edition,revised in 2020)》 points out that it pays attention to the deep integration of information technology and mathematics curriculum,improves the effectiveness of teaching,and encourages students to use information technology to learn,explore and solve problems.In the past research,most of the research is about the application of information technology in mathematics teaching,but there is a gap in the teaching research of cultivating students’ mathematics core literacy under information technology.As one of the main lines of high school mathematics teaching content,function plays an important role.Its basic ideas and methods run through the whole basic teaching,which can cultivate students’ core qualities in mathematics.It is a common mathematical tool for students to further study and work so that function is the focus of the college entrance examination over the years.However,there are many problems in the function teaching,which not only affect the students’ mastery of the function knowledge,but also hinder the formation of the basic ideas and methods of function and the cultivation of mathematics core literacy.Combined with the era background and realistic background,this study mainly explores the teaching of high school function based on Geo Gebra software to cultivate the core literacy of mathematics,and is devoted to finding the effective combination of mathematics core literacy,function teaching and information technology,optimizing mathematics classroom with the support of information technology,and promoting the development of students’ mathematics core literacy.In this study,the method of literature,experimental research,questionnaire and interview were used.The first part expounds the background of the question,the content and significance of the study.The second part uses the literature method to understand the research status of mathematical core literacy and Geo Gebra software by sorting out relevant literature and materials,and discovers the research gap of cultivating mathematical core literacy based on Geo Gebra software.The third part is the construction of theory,first of all,the author learns Geo Gebra software through the network learning platform,and summarizes its functions and software advantages in function teaching,providing technical support for the research.Secondly,combined with the new textbook and the new curriculum standard to understand the function content of high school and the requirements of cultivating mathematics core literacy to provide content support for the development of research;Finally,Piaget’s theory of cognitive development,mathematical multi-distance representation theory and scaffolding teaching theory are found to provide theoretical support for the research.The fourth part is the combination of theoretical analysis and practical teaching experience,from the perspective of using Geo Gebra software to solve the problems in function teaching,so as to better cultivate the core literacy of mathematics involved in function teaching based on Geo Gebra software.The fifth part aims at the above reasons and provides corresponding teaching cases based on the functions and advantages of Geo Gebra software,providing some references for the practice of front-line teachers.In the last part,two classes in grade one were selected to carry out a comparative experimental study,which confirmed the effectiveness of the functional teaching research based on Geo Gebra software to cultivate mathematical core literacy through the comparison of results.Through the analysis of the questionnaire survey and interview with teachers,the effect and concrete implementation suggestions of cultivating mathematical core literacy based on the software are obtained.
