Development and Design of Senior High School Solid Geometry Courseware Based on GeoGebra:A Case Study of Frustum cone

In the teaching practice of senior high school solid geometry, it is typical of a teacher to show some pictures and draw some pictures to give a static presentation of the content of learning. GeoGebra, as an outstanding mathematics teaching software, boasts its many advantages in developing interactive mathematics coursewares in the following aspects: con- venient mathematical operation; sufficient modes available for interaction; powerful self-defining orders and abundant function- al zones. Take the recognition of the frustum cone for example, through a global analysis of the content in the whole chapter, six parts of content that is in need of dynamic presentation are decided on and based on the real teaching needs, the correspond- ing functions are designed for the courseware. Finally, by use of the GeoGebra an interactive courseware is developed. The GeoGebra-based courseware development of Senior high school maths teaching via dynamic switch of graphs and computer-ai- ded teaching through self-defining instructions is conducive to students’ understanding of abstract knowledge, which can help substantiate the abstract, thus to arouse students’ learning interest and inquisitive mind.
