Study On The Application Of Geometric Sketchpad In Mathematics Teaching In Senior Middle School

In the macro sense,mathematics is a science that studies the concepts of quantity,structure,change,space and information,it plays an important role in the development of science and technology and the progress of human society,so it is necessary to study and study mathematics.The study of mathematics in high school is of great significance to the improvement of individual mathematics ability and mathematics accomplishment.But,the higher level of abstraction,more rigorous and abstract than junior high in formulation of mathematics language,different ways of thinking and other characteristics create some difficulties for students to study.With the rapid development of information technology,it brought great opportunities to the high school mathematics teaching.Geometric Sketchpad is an excellent electronic drawing tool.It is easy to operate and it can draw accurate and dynamic figures with ruler and rule to show them to students,so that students can understand knowledge more vividly.This paper aims at the difficulty of high school mathematics teaching,use Geometric Sketchpad to Assist Teaching,and take the function as an example to study the case teaching,in order to further improve the high school mathematics teaching effect and learning quality.First of all,this paper reviews and summarizes the relevant research results on the application of geometric drawing board and the teaching of geometric drawing board assistant at home and abroad,at the same time,this paper analyzes the research status of "function teaching" in the last five years,combined with the current situation of high school mathematics teaching,the main content and research ideas of this paper are put forward,at the same time,it expounds the constructivism learning theory,audio-visual teaching theory and humanistic learning theory,which provides the theoretical basis for this study,and also provides the scientific basis for the follow-up case design of the author.Secondly,in order to further understand and master the current high school mathematics teaching and geometric Sketchpad assisted teaching application status this paper selects four high schools in Baoji and Hanzhong,a questionnaire survey was conducted for senior high school math teachers and interviews were conducted for students.Based on the data statistics of the questionnaire and the analysis of the interview results,it further reveals the current situation and problems of the application of mathematics teaching and geometry Sketchpad assisted teaching insenior high school.On this basis,combined with the local practice,this paper puts forward the suggestions and Strategies of geometry Sketchpad assisted teaching.Finally,this paper takes the function in the mathematics textbook of Senior High School of Beijing Normal University in 2014 as an example,comprehensively combing the teaching content of function part and constructing thought map of function teaching,for the monotonicity of functions and other seven content,give full play to the advantages of geometric sketchpad,combining relevant learning theories,carefully designed teaching cases,to improve the effect and quality of function teaching,it also provides important reference for high school function teaching.
