Case Study Of Junior Middle School Mathematics Teaching Based On Geometric Sketchpad

In the 21 st century,the knowledge economy is the leading information technology is developing rapidly,more and more attention at home and abroad education information.In particular,in terms of mathematics disciplines,which are known for cultivating logical thinking,its teaching not only requires teachers to have profound mathematical knowledge,but also need to master certain modern information technology.Traditional blackboard teaching has been difficult to meet the needs of information age development.The new curriculum reform advocates the integration of modern educational technology into the mathematics classroom,but how to use the information teaching software in the mathematics classroom has always been the problem that the mathematics teacher needs to solve.In the commonly used mathematical software,geometric drawing board with dynamic presentation,mapping precision,measurement,calculation,mathematical experiments and other functions,can better optimize the junior high school mathematics classroom teaching.In this study,the literature research method,questionnaire survey and comprehensive analysis,analysis and research of junior high school mathematics teaching status quo.Firstly,the background of the research and the present situation of the Geometer's Sketchpad Assisted Mathematics Teaching at home and abroad are summarized.Secondly,this paper expounds the basis of the research,including the function and value of the Geometer's Sketchpad,the relevant literature review and the theoretical basis of the study.In addition,the junior middle school mathematics three plate based on the application of case knowledge,the Geometer's Sketchpad in function,geometry and probability statistics are analyzed and discussed,and the quadratic function and the Pythagorean theorem for teaching case,the application of the Geometer's Sketchpad is designed.The purpose of this study is to inject new vitality into junior middle school mathematics teaching reform,and to provide theoretical and practical reference for the application of geometric drawing board in junior middle school mathematics classroom teaching so as to make geometric drawing board a powerful tool to assist junior middle school mathematics teaching.
