Research On Teaching Practice Of Dynamic Geometry Problems In Junior High School Based On GeoGebra

With the rapid development of modern information technology,traditional teaching methods have not complied with the development of the times.In the process of dynamic geometry teaching,teachers need to integrate modern information technology and course content,improve teaching quality and effect by improving teaching methods and optimizing teaching process.At the same time,teachers should also pay attention to cultivating students’ ability to use dynamic mathematics technology for autonomous learning,Further improve students’ interest in learning and ability to solve problems.In view of this,combined with the visualization and experimental inquiry characteristics of geogebra,the problems to be solved in this paper are:(1)how to use geogebra to assist dynamic geometry teaching in junior middle school,how to improve students’ ability of visual imagination,raising and discovering problems;(2)What is the teaching effect of integrating dynamic geometry problems by geogebra;(3)How can junior middle school mathematics teachers make better use of geogebra to teach dynamic geometry.Based on the above thinking,this paper mainly adopts the research methods of literature research,case study,experimental research,test paper,questionnaire and so on.First of all,through consulting and sorting out the relevant literature,we can understand the current situation of the application of information technology in education and teaching,and sort out the relevant theoretical basis;Secondly,according to the practical teaching experience and geogebra’s own functional characteristics,geogebra is used to design typical cases from three angles,including explanation teaching design,inquiry teaching design and demonstration teaching design;Finally,two parallel classes in Grade 8 of XX middle school in Tianshui city are selected for experimental research.Class 11 of Grade 8 is the experimental class,and class 16 of Grade 8 is the control class.Then the experimental class and the control class are given practical teaching.The experimental class adopts geogebra fusion dynamic geometry problem teaching,and the control class adopts traditional teaching methods.After the experiment,the post-test scores of the students in the experimental class and the control class are counted,and the independent sample t-test is carried out,At the same time,questionnaires were distributed to the students in the experimental class to statistically analyze the impact of geogebra assisted dynamic geometry teaching on students from four dimensions,including students’ learning status,acceptance of geogebra software,learning effect and ability training.Through practical teaching,this study verifies that the use of geogebra assisted dynamic geometry teaching in junior middle school can change teachers’ teaching methods,enrich classroom teaching contents,optimize classroom teaching process,and mobilize students’ learning enthusiasm,so as to improve students’ mathematical performance,cultivate students’ ability to find and raise problems,and develop students’ geometric intuition and innovative consciousness.
