Researching Support Materials for Geometry Education Software

几何被许多数学教育者视为向学生介绍高阶数学思维的自然背景。第一阶段小企业创新研究（SBIR）的研究结果为一种新的教育软件工具——the Geometer’s Sketchpad——建立了技术基础，该工具的目的是提供一个具有动态结构的视觉环境，允许学生以迄今为止不可能的方式研究几何形状和关系。第二阶段的研究目标主要集中在：(1)原型教材的开发与测试；(2)原型软件的开发与测试；(3)使用The Geometer’s Sketchpad对不同学生群体的态度和成就进行评估；(5)使更广泛的学生可以使用几何画板。该项目将为应用程序提供软件，包括软件的增强版本、用于其他硬件平台的版本、外语版本，以及面向中学、小学和大学受众的书籍和草图/脚本集。

Geometry has been viewed by many mathematics educators as a natural context in which to introduce students to higher-order mathematical thinking. Results of the Phase I Small Business Innovation Research (SBIR) study establish the technical basis for a new educational software tool, The Geometer's Sketchpad, that has as its purpose the provision of a visual environment with dynamic constructions, allowing students to investigate geometric shapes and relationships in ways that have heretofore not been possible. The research objectives of the Phase II research focus on (1) development and testing of prototype classroom materials; (2) development and testing of prototype software; (3) assessment of attitudes and achievement among various student populations using The Geometer's Sketchpad; and (5) making The Geometer's Sketchpad accessible to the broadest range of students. The project will provide software for applications that include enhanced versions of the software, versions for other hardware platforms, foreign language versions, and books and collections of sketches/scripts for secondary, elementary, and university audiences.
