9561674 Jackiw This Small Business Innovation Research Phase I project establishes the groundwork for the development of interactive and exploratory geometry-learning software realized on inexpensive, pen-based, and handheld computers. The research draws on Key Curriculum Press's existing dynamic geometry software--The Geometer's Sketchpad--and on the accessibility afforded by handheld technology (currently in the form of "graphing calculators"). The proposed research will develop classroom scenarios of pen-based devices used in classrooms, taking into account possibilities for interaction with desktop-based computers. These scenarios will be used to develop algorithms for pen-based geometry input, prototypes of a pen-based Sketchpad product, and specifications for a minimal hardware platform for launching this new technology in a mathematics education context. The Geometer's Sketchpad enjoys a position as a well regarded and commercially successful educational software system. The proposed project, led by Sketchpad's original author and ongoing project director, will pave the way for migrating this software to a new and promising hardware platform on the horizon of educational technology. The project has outstanding potential for commercial success in school markets because it represents an environment which is educationally sound (in that it draws on the existing Sketchpad), widely accessible (in that it is both portable and inexpensive), and ideally suited for exploring mathematics (because it is pen-based).

9561674 Jackiw这个小企业创新研究第一阶段项目为开发交互式和探索性几何学习软件奠定了基础，该软件是在廉价的、基于笔的手持计算机上实现的。这项研究利用了Key Curriculum Press现有的动态几何软件——The Geometer’s Sketchpad——以及手持技术提供的可访问性（目前以“图形计算器”的形式）。拟议的研究将开发在教室中使用的基于笔的设备的课堂场景，考虑到与桌面计算机交互的可能性。这些场景将用于开发基于笔的几何输入算法，基于笔的Sketchpad产品的原型，以及在数学教育环境中启动这项新技术的最小硬件平台的规范。几何学家的Sketchpad享有的地位，作为一个良好的和商业上成功的教育软件系统。该项目由Sketchpad的原作者和正在进行的项目主管领导，将为将该软件迁移到一个新的、有前途的教育技术硬件平台铺平道路。该项目在学校市场上具有显著的商业成功潜力，因为它代表了一个教育上合理的环境（因为它利用现有的Sketchpad），广泛的可访问性（因为它既便携又便宜），并且非常适合探索数学（因为它是基于笔的）。
