Teaching Research On The Lower Grade Mathematics Of Linglong Drawing Board

With the advancement of science and technology and the continuous improvement of academic requirements,various teaching aids are widely used.In the field of mathematics teaching,in order to better achieve multi-dimensional representation,breakthrough teaching and difficulty,dynamic mathematics teaching software shows its own unique charm.As one of the dynamic mathematics teaching softwares,Linglong drawing board can quickly draw and dynamically display various geometric and functional graphs,and make great use in high-level and junior high-level plane geometry,solid geometry and functions.Throughout the learning content of the elementary school mathematics textbooks,in the middle and upper grades of elementary school,such as the polygon area,the cut of the figure,the surface area of the cylinder,the volume of the cylindrical cone,the statistical graph,etc.,can be presented using the exquisite drawing board.Then in the lower grades,that is,the first and second grades,does the exquisite drawing board have its available points,and how to use it? Based on the above considerations,this thesis will help the Linglong drawing board to assist the mathematics teaching in the lower grades of elementary school,especially the theoretical and practical research on how to use the lower grade mathematics in the classroom.Theoretical research mainly summarizes the development history and current situation of Linglong drawing board software.Based on the mathematical multi-representation learning concept,it discusses the four principles of designing exquisite drawing board integrators:information packaging principle,spatial proximity principle,time proximity principle and consistency principle.Based on these four principles,we have designed a number of exquisite drawing board parts suitable for the mathematics classroom in the lower grades of elementary school: understanding of the number of thousands,recognition of hundreds of tables,observation of angles,observation of objects,recognition of clocks,counters,etc.In practical research,we focus on teaching experiments and discuss the application of integrable cases in mathematics classrooms.Studies have shown thatin the lower grades of decimal mathematics,the exquisite drawing board is also used for the production and teaching of the integrators.The use of exquisite drawing board for auxiliary teaching can highlight the difficulty and difficulty,stimulate students' enthusiasm for learning,enhance the vividness of teaching design,help to improve students' intuitive imagination,and promote the improvement of students' learning ability.
