Mathematical Sciences (21) The PascGalois Project is developing materials that use computing technology to enhance the teaching of abstract algebra which has traditionally been one of the most difficult and least visual subjects in the undergraduate mathematics curriculum. These materials provide an interesting class of objects and computer generated representations that allow students to "see" numerous algebraic concepts. This project has its origin in a simple exercise with Pascal's triangle. The interest in this construction lies in the fact that Pascal's triangle mod n is the group multiplication for the cyclic group Z . This construction is being generalized using other finite groups. Like Pascal's triangle mod n, PascGalois triangles can have self-similar properties. Many of these properties can be described using subgroups, quotients, and automorphisms of the group G. The project is developing software to create these images and higher dimensional generalizations (e.g. automata, similar to Conway's Game of Life) on demand so that students can investigate these patterns and their relationships to group structure. The primary objectives of the project are: to develop laboratory exercises that provide a visual component for the junior/senior level Abstract Algebra courses; to develop students' visual and intuitive understanding of difficult concepts; to model effective use of technology for prospective mathematics teachers and thus better prepare them to implement the National Council of Teachers of Mathematics standards; to stimulate interest in abstract algebra and encourage graduate study in mathematics, and to increase participation in undergraduate research in mathematics by providing a source of interesting and accessible research projects.

数学科学 (21) PascGalois 项目正在开发使用计算技术来加强抽象代数教学的材料，抽象代数历来是本科数学课程中最困难和最不直观的科目之一。这些材料提供了一类有趣的对象和计算机生成的表示，使学生能够“看到”许多代数概念。这个项目起源于帕斯卡三角形的简单练习。这种构造的有趣之处在于帕斯卡的三角形 mod n 是循环群 Z 的群乘法。这种构造正在使用其他有限群进行推广。与 Pascal 的三角形 mod n 一样，PascGalois 三角形也可以具有自相似的性质。其中许多属性可以使用 G 群的子群、商和自同构来描述。该项目正在开发软件来根据需要创建这些图像和更高维的概括（例如自动机，类似于康威的生命游戏），以便学生可以进行调查这些模式及其与群体结构的关系。 该项目的主要目标是： 开发实验室练习，为初级/高级抽象代数课程提供视觉组件；培养学生对困难概念的视觉和直观理解；为未来的数学教师建立有效使用技术的模型，从而更好地让他们做好执行国家数学教师委员会标准的准备；激发对抽象代数的兴趣并鼓励研究生学习数学，并通过提供有趣且易于理解的研究项目来增加本科生对数学研究的参与。
