Design And Implementation Of Plane Geometry Education Resource Database Based On Dynamic Geometry

With the rapid development of computer and network technique in recent years,network education,as a new education model,has became an important part of modern education technique .Network-education resource system,as a main application of computer and network in educational field,is attracting more and more concerns .An well -designed resource system can efficiently organize all kinds of education material and apply it to everyone which takes part in education .Nowadays Education resource databases mainly focus on courseware, retrieval through Catalog directory or keyword by means of common retrieval interfaces. It is not appropriate to retrieval through keyword for geometrical resource databases based on geometric forms.This system based on dynamic geometry extracts characteristic information and drawing instruction sequences to the geometric forms and stores them instead of geometric forms,saving storage space. characteristic information combined with model recognition technology realize searching geometry proposition by geometry relationship.Chapter I simply introduces Education resource database research background,its status quo and the work of the paper.Chapter II introduces dynamic geometry, related concepts and data structures, and particularly describes their roles in this system.Chapter III author introduces the technology and principle related to the realization of retrieval, detailedly explains three functions related to retrieval and offers retrieval examples.In the Chapter VI,the last part of this paper,describes the significance of this paper and discusses several potential ways that can improve the system.
