Research On Teaching Of Graphics And Geometry In Primary School With Linglong Sketchpad

The wave of the current Internet and mathematics education hit,mathematics education technology has become the tool of improving students' mathematical cognitive.As a modern mathematics education technology,Linglong Sketchpad is a platform of mathematics education in realizing mathematics knowledge and thinkingvisualization.The" curriculum standards(2011 Edition)" of our country pointed out that the information technology should be treated as an auxiliary tool,which the teachers engaged in teaching and research,the students engaged in mathematics learning ctivity and evaluation of students' Mathematics Learning.Graphics and geometry is the main line through primary school mathematics knowledge,and is also the foundation of learning mathematics graphics and geometry in junior high school and senior high school.The concept and character of graphics and geometry in primary school are theimportant points and difficult points of students' learning,on the one hand,students dauntedbecause of the abstraction of geometry concepts and the generalityof nature;on the other hand,the primary school students' thinking level is still in the stage of the transition from concrete image thinking to abstract thinking,and can't understand the concepts and properties of geometry well.As a practical and flexible dynamic mathematical teaching software,with the functions of mathematical visualization and mathematical dynamic,Linglongsketchpad aims at dynamicvisualization of mathematical objects and it perhaps can highlight the teaching important points and solve the teaching difficult points,improve teaching effectiveness.This study will be carried out from theoretical research and practical research.In the theoretical research,through the experience summary and theoretical analysis and other methods,Firstly,summarize the features and functions of Linglong Sketchpad software,then on the basis of theMulti-representationconcept discuss the principles of designingLinglong Sketchpad integrable ware:principles of package information,space nearby principle,time nearby principle and the consistency principle.Finally,according to the principles,design several cases of integrable ware from three sides of basic teaching analysis,production process the basic principle and application.In practical research,given priority to the teaching experiment,questionnaire and case interview are complementary.Testingthe influenceof applyingLinglong Sketchpad assisting primary graphics and geometry teachingon students' epistemologicalbeliefs,emotional attitude and mathematical learning ability.The results show that:(1)The experimental class students'math grades have improved significantly.(2)The experimental class students' epistemic beliefs and emotional attitude have improved significantly.(3)The experimentalclass students' mathematical ability has not been significantly improved.
