Research On The Application Of Geometry Sketchpad In Visualization Teaching

"Compulsory Education Mathematics Curriculum Standard(2011 Edition)" began to attach importance to the rational use of information technology in mathematics teaching,improve the traditional teaching and learning mode,and improve teaching efficiency.Among them,"triangle" is an important content of junior high school mathematics,and it is also the basis for students to learn geometry.Therefore,it is very necessary to understand how to use information technology to solve the triangle problem in junior high school.Among many information teaching tools,Geometer's Sketchpad is easy to operate,and its functions of accurate drawing,dynamic display and experimental exploration are very suitable for transforming abstract geometric problems into concrete problems,which can be directly displayed to students through visual senses.Therefore,combined with the relevant literature of the integration of the visualization teaching of Geometer's Sketchpad and junior high school mathematics teaching cases,as well as the requirements of the new curriculum reform,and based on the cognitivism,audio-visual teaching theory and intuitive learning theory,the author carries out a comparative experiment on the teaching of the "triangle" chapter in two classes of grade one in a middle school in Zhangzhou,using the Geometer's Sketchpad visualization teaching model respectively According to the test results,this paper analyzes the influence of the visualization teaching of Geometer's Sketchpad on students' triangle learning,and conducts stratified sampling interviews with students to understand their attitudes towards the two teaching modes,so as to put forward corresponding suggestions for the problems existing in junior high school students' mathematics geometry learning,so as to improve their mathematics learning It's the same level.The results of the experiment include: 1First,through SPSS analysis of the test results of the control experiment,it is found that the total score of the experimental class is 72.27 ± 25.39,which is higher than 59.96 ±31.94 of the control class,and the average difference between the two classes is 12.31.It is concluded that the visual teaching of Geometer's Sketchpad is more effective than traditional teaching methods in triangle problems.Secondly,the application of visualization teaching mode of Geometer's Sketchpad in junior high school geometry teaching has a positive impact.Through the design and implementation of visualization teaching of Geometer's Sketchpad in the integration case of triangle in junior middle school,the unique visualization function of Geometer's Sketchpad provides many convenient conditions for teachers in the teaching process,which makes it easier for students to understand abstract geometric problems,and has more motivation and enthusiasm in the learning process.Third,most of the students support the use of Geometer's Sketchpad for visualization teaching.Most students are willing to continue to accept the visualization teaching mode of Geometer's Sketchpad,but a few students still can't accept it.They think that Geometer's Sketchpad is not helpful to their learning,and sometimes it makes the classroom content more complex.
