Research On The Application Of Geometric Sketchpad Into Mathematics Teaching In Junior Middle School ——Taking Hunan Education Edition As An Example

The upsurge of the new curriculum reform is gradually surging up,and the change of teaching methods is gradually popular.The application of information technology in the classroom has technical support for the change of teaching methods.At the same time,the state attaches great importance to the integration of information technology and curriculum teaching.Geometric Sketchpad is powerful and easy to use,which provides a good opportunity for information technology to assist mathematics.Based on this,the author studies the application of Geometric Sketchpad in junior middle school mathematics of Hunan Education Edition.Using the methods of literature analysis,classroom observation,interview and physical analysis,this paper analyzes the part of junior middle school mathematics textbooks suitable for using geometric sketchpad teaching in Hunan Education Edition.Based on the training of Suzhou g teacher on the use of Geometric Sketchpad in school a,three sample teachers were selected for public class display and experiments.Through interviews with the teachers in public class,peer teachers and randomly selected students,Classroom observation and physical analysis of classroom homework,get the effect of geometry Sketchpad assisted junior middle school mathematics teaching.The research conclusions are as follows: in "number and Algebra",Geometric Sketchpad can draw function images,explore the properties of functions and function synthesis problems,explore the relationship between theorems,geometric properties and geometric quantities,and dynamically demonstrate the simple transformation of geometric graphics in "graphics and geometry".There are four "synthesis and practice" parts in the mathematics textbook of Hunan Education Edition,which require the use of geometric sketchpad for teaching to improve students’ comprehensive strength.Teaching effect:（1）mobilize students’ enthusiasm in class,improve the classroom atmosphere,and students talk enthusiastically in class.（2）The image and dynamic break through the important and difficult points of teaching,and students’ mastery of knowledge is more solid.（3）Cultivate the spirit of students’ joint exploration and research.（4）It improves the efficiency of teaching and can teach more knowledge in class.
