Visual Geometry

这个名为视觉几何的项目正在制作新的协调的多媒体几何材料：用于高质量视觉图像的三维图形的计算机动画录像带，用于构建和研究三维图形的相关练习册，以及用于交互学习相关二维几何概念的微型计算机程序。几何画板将是一个通用的二维绘图程序，设计用于构造和操作几何图形。它对标准几何体材质和此项目产生的单位都很有用。这些教材被设计成适合标准的高中课程，并且将足够灵活，可以供整个班级、小团体学生使用，甚至可以供个人学习。这些材料的制作方式是为了吸引那些希望提高视觉几何技能的人，即使他们不是在上几何课程。整个计划正在接受彻底和广泛的测试。此外，教育署亦会制作录影带，让教师熟悉教材的用途。有广泛传播的计划；项目工作人员还将利用日益增长的家庭学习视频市场。在一个试点项目中，提出者建立了一个微型计算机系统，以制作专业质量的三维几何概念视频动画。除了该项目制作的材料外，工作人员还将能够向希望与动画录像带和视盘媒体合作的其他人提供软件和信息。//

This project, Visual Geometry, is producing new, coordinated, multi-media geometry materials: computer-animated videotapes of three-dimensional figures for high quality visual images, associated workbooks for constructing and investigating three- dimensional figures, and a microcomputer program for interactive study of related two-dimensional geometry concepts. The Geometer's Sketchpad will be a general purpose, two-dimensional drawing program designed for constructing and manipulating geometric figures. It will be useful with both standard geometry materials and with the units produced by this project. The materials are being designed to fit into the standard high school curriculum, and will be flexible enough to be used by an entire class, small groups of students, or even for individual study. The materials are being done in a way to be appealing to people who wish to improve their visual geometry skills, even if they are not taking a geometry course. The entire program is being thoroughly and broadly tested. Additional videotapes to familiarize teachers wit the uses of the materials will also be made. There are plans for broad dissemination; the project staff will also take advantage of the growing market in home-study video. In a pilot project, the proposers have set up a microcomputer system to produce professional quality video animation of three- dimensional geometry concepts. In addition to the materials produced by the project, the staff will be able to provide software and information to others who wish to work with the media of animated videotapes and videodiscs.//
