Study On The Application Of Computer 3D Technology In Solid Geometry

Information Technology has brought profound influence to learning and teaching. How to integrate information technology and course to make learning effect optimization is one of the emphases of educational technology research. Solid geometry is important in middle school. It has significant function to cultivate students'spatial imagination ability and abstract thinking ability. Because of the influence of plane geometry's negative transfer and teaching tool's limits in expression, it is one of the difficult courses that students think.With the development of the net technology and the computer technology, the computer has developed from the two-dimensional plane space to the three-dimensional solid space. People have paid more attentions to three-dimensional graphics and images processing technologies. Three-dimension technique always keeps great life since its birth, now it has been widely used in the fields of animation, image transfer, industrial design and game amusement. As a proven technology, it also attracts the attention of education.The research first make the feasibility analysis. Using computer three-dimensional technology in three-dimensional solid geometry teaching is teaching needs, because of the characteristics of computer three-dimensional technology and the solid geometry teaching needs and characteristics, and analyze their theoretical feasibility. Three-dimension technology as an important part of information technology, it has particular advantages in solid geometry if under the guidance of appropriate teaching design.Second,the basic theoretical support. To find the theoretical support for the application of computer three-dimensional technology in Solid Geometry, such as Dell's"tower of experience"theory, AuSubel's meaningful reception learning theory. Theoretically show the feasibility of application. Third,analysis the three-dimensional geometry teaching software design. Analysis of teaching characteristics and the principles of three-dimensional geometry teaching software, select the appropriate three-dimensional production software, according to the general process of system design, and combined with the characteristics of computer three-dimensional technology and solid geometry, designs the three-dimensional geometry teaching software. Last,develop the three-dimensional geometry teaching software. According to the system design methods and with examples, showing the complete soft development process, complete the development of the three-dimensional geometry teaching software,and make a simple software application testing, preliminarily verifies the feasibility and effectiveness of the three-dimensional geometry teaching software.There are two innovative points of this research,first is put forward the computer three-dimensional technology in solid geometry teaching ideas, combined with 3DS MAX and Cult3D develop a simple three-dimensional geometry teaching software, providing a method reference for the application of computer three-dimensional geometry in solid geometry.The other side,the design of the three-dimensional geometry teaching software, taking into account the theory of design and software design, to a certain extent, improve the difficult issues of present solid geometry model, and provides a new choice of presented for the solid geometry model.
