A Pilot Project for an Introductory Level Geometry Course

正在编写一门一年级/二年级的几何课程的文本和材料。本课程将强调画法几何(覆盖三维物体，了解透视)，瓷砖和多面体(对称性，条状图案，壁纸组，空间填充形状)，曲率，欧拉特征，几何和创意艺术，通过引导发现的方法探索几何。它的设计将满足未来中小学教师的需求。该项目建立在埃克森基金会帮助下开始的工作基础上。它包括与康奈尔大学建立联系的多所大学的教师参与。该项目的目标是制作、实地测试和商业出版19个单元的文本和课程材料。

Text and materials for a freshman/sophomore-level geometry course are being developed. The course will stress descriptive geometry (draping three-dimensional objects, understanding perspective), tiling and polyhedra (symmetry, strip patterns, wallpaper groups, space filling shapes), curvature, Euler characteristic, geometry and the creative arts, exploring geometry through the method of guided discovery. It will be designed to meet the needs of prospective elementary and secondary school teachers.The project builds on work begun with the help of the Exxon Foundation. It includes participation by instructors at a variety of colleges with whom Cornell has established ties. The project goal is to produce, field test and commercially publish nineteen units of text, and course materials.
