The Application Study Of Geometer’s Sketchpad Solve The Dynamic Geometry Teaching In Junior High School

Today’s society is a highly developed information society,information technology has penetrated all aspects of production and life,education is no exception.in recent years,the middle school mathematics education form is becoming more and more information is the best evidence.Computer Aided Instruction(CAI)Has become the main mode of mathematics teaching,and the teaching reform based on it has also appeared in a large number of secondary schools.The content of the reform has been extended from the reform of curriculum content to the reform of teaching methods and learning methods.The Geometer’s Sketchpad is a software platform suitable for geometry teaching,including plane geometry,analytic geometry,and projection geometry,etc.It provides an environment for students and teachers to explore the inner relationship between algebra and geometry graphics,offering rich and convenient functionality on creativity so that users can write their own teaching courseware at will.It can be said that geometry sketchpad is one of the most outstanding mathematics teaching software.Since the localization of this software in 1996,it has been popular among mathematics teachers.A lot of studies on teaching reform,both at home and abroad,are based on this software.For a long time,the moving point problem frequently appears in the final Yunnan high school entrance examination in mathematics.It can be said that the moving point problem is the highest peak of Yunnan junior high school mathematics.The difficulty in Yunnan junior high school teaching is:How to let students intuitively "see" the moving point,realizing the impact of the point movement on the geometric figure produced by the point.The software function of geometric sketchpad provides a new way to solve this difficulty.The author summarized the teaching mode of geometric sketchpad in mathematics class by conducting practical research on his own classes,found the misconceptions of geometric sketchpad when used in mathematic teaching.Meanwhile,this paper compiled a special study plan which can be applied to the mathematical teaching on moving point problems in Yunnan junior middle schools,in the process of practical research.
