历史上，美国 Key Curriculum Press 公司最早提出了《几何画板》的概念模型并开发了一个具体的应用软件。该软件系统在CAI领域产生了巨大影响。《几何画板》虽然在表现平面几何教学方面有出色表现，但在空间(三维)几何表现方面则不尽人意，因为该软件是基于微软的GDI二维图形库来开发设计的。而空间几何关系的展现又是中小学数学教学中的重点和难点，最需要使用计算机辅助教学手段帮助学生直观地加以理解。笔者开发的《三维几何画板》以弥补《几何画板》在空间表现方面的不足，文中介绍了该软件体系结构中MVC设计模式的一种变体“文档-视图设计模式”的应用方法。说明了在某些情况下，为什么使用MVC模式的文档-视图变体可能会更加合适。并且详细阐述了文档-视图设计模式的实现方法及其各部分与模型-视图-控制器模式之间的对应关系。

In history,the Key Curriculum Press in USA is the first to propose a conceptual model of the Geometer's Sketchpad and devel-op a specific application software,which has had a tremendous impact in the field of CAI. Geometer's Sketchpad is excellent in the plane geometry teaching,but it is unsatisfactory in space (3D) geometry performance,because the design is based on Microsoft GDI 2D graph-ics library. Spatial geometric relationship is the emphasis and difficulty in mathematics teaching at middle and primary school,and it most needs to use computer-aided teaching methods to help students understand intuitively. Develop 3D Geometric Sketchpad to make up for the lack of space performance of the Geometer's Sketchpad,it has introduced the applications of a variant of MVC Design Pattern-the Doc/View Design Pattern. It has pointed out why in some cases the Doc/View Design Pattern is more suitable than the MVC Design Pat-tern. It has illustrated the implementing methods of the Doc/View Design Pattern in detail and had also pointed out the correspondences between the various parts and MVC pattern.
