SBIR Phase I: Pen-Based Geometer's Sketchpad

小行星9561674 这个小企业创新研究第一阶段项目建立了互动和探索性的几何学习软件的开发基础上实现的廉价，笔式和手持计算机。 这项研究利用了Key Curriculum Press现有的动态几何软件--几何画板--以及手持技术（目前以“图形计算器”的形式）提供的可访问性。 拟议的研究将开发教室中使用的笔式设备的教室场景，同时考虑到与桌面计算机交互的可能性。 这些方案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，以及在数学教育背景下推出这种新技术的最小硬件平台的规格。 几何画板享有的地位，作为一个良好的考虑和商业上成功的教育软件系统。 由Sketchpad的原作者和正在进行的项目总监领导的拟议项目将为将该软件迁移到教育技术领域新的有前途的硬件平台铺平道路。 该项目在学校市场上有着巨大的商业成功潜力，因为它代表了一个教育环境（因为它借鉴了现有的画板），广泛使用（因为它既便携又便宜），非常适合探索数学（因为它是笔式的）。

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).
