Study Of Three-dimensional Technology In The Teaching Of 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..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 paper first analyzes the characteristic of solid geometry and derives a conclusion form the teachers' interview and students' questionnaire: three dimension technique as an important part of information technology, it has particular advantages in solid geometry, if under the guidance of appropriate teaching design. Second the paper analyzes the characteristic of three dimensional teaching tools and finds that: the lack of platform's well applicability limits its application in actual teaching. So penman use three dimensional development tools, combine the characteristic of solid geometry, under the guidance of software engineering theory, try to develop a three dimension platform which fits for solid geometry teaching and learning. At last, the paper evaluates the platform's application, summarizes its merits and shortages and discusses what to do in the future about three dimension technique in solid geometry.In a word, the paper makes a detailed research about three dimension technique's requirement analysis, platform development, practice application and its long term potential in solid geometry, makes the integrate of three dimension technique and solid geometry into reality.
