Research On Calculus Teaching In Senior High School Based On Geogebra

With the coming of 5g era,the development of Internet is more and more vigorous and rapid,and effective use of its resources in our education and teaching will make our teaching process even more powerful.Therefore,the teaching concept of "visual teaching" is born with the trend.The purpose of visual teaching is to express students' thinking directly by means of "figure" and "operation",so that students' thinking can be visualized.Therefore,when it is applied to the classroom teaching of middle school mathematics,the abstract knowledge in mathematics can be turned into concrete knowledge,which will play a finishing point for the classroom teaching of middle school mathematics.It is self-evident that the first mock exam is a mathematical content in the middle school.The appearance of calculus laid an important foundation for the development of modern mathematics,and also provided a material premise for future generations to use mathematical models to do research in various fields.Therefore,calculus has been introduced into the teaching of mathematics classes in middle schools and universities.In the middle school stage of calculus teaching,mastering the better calculus basic theory and thinking method,this stage of mathematics learning and even after the university mathematics learning has a better guiding role.But limited by the abstraction of calculus,for most beginners in high school,understanding has become a problem,let alone their interest.Based on the learning concept of constructivism,Ausubel's learning motivation theory and dobinsky's APOS concept teaching theory,this study uses the dynamic mathematical mapping software geogebra to design the teaching of "rate of change and derivative","monotony and derivative of function" of calculus module in senior high school mathematics,as well as an exercise of "locus of tangent intersection of function" The purpose of teaching is to help students deepen the idea of the combination of number and shape.After the completion of the teaching design,two parallel classes of senior two were selected to carry out teaching practice.Through the data analysis of the unit test scores of the two classes,as well as the analysis of the questionnaire issued to the experimental class and the interview with the teachers,it was concluded that: compared with the traditional teaching mode of calculus,the effect of geogebra assisted calculus teaching was better and more significant In order to reduce the abstraction of the module and increase the class appeal of the module.
