The main issue of this paper is to discuss the conceptual tools and the figural meaning provided by the dynamic geometry software as well as the interaction between constructing mathematical meaning and tools.Information technology fits into teaching is one of the trends for mathematics education study. It is also a focal point of the practical development of Mathematics education. Both information technology and the Mathematics software generated from it, such as DGS. DAS, and DSS, are emphasizing the functions of Dynamic Multimedia Interactive Representations. Using Information Technology properly to design teaching contents, learning tools and forms of representations are the three key elements for research and practice of this field. This paper will take Dynamic Geometry Software as an example to express the functions and the meanings of the three elements, and also the interactive relationships between the above two and the construction of Mathematical concepts.
