自从计算机被引入数学教学以来。已经开发了几个软件，旨在改进学习过程。几何是一个知识领域，特别是涉及越来越多地使用软件在教学中。这是因为外部表示法（通常称为图形）所起的重要作用，以及专门为几何设计的软件使处理这些表示法的新方法成为可能。计算机不仅提供了比纸笔环境更快、更精确的绘图工具。而且还用于移动或修改图形，因此通常使用户能够容易地可视化几何推进。本章讨论的问题涉及这些软件引入教学和学习过程的变化。这些变化将主要讨论以下方面：i）计算机介导的几何图形的新地位; ii）学生在计算机上执行任务时的行为。
Since computers have been introduced to the teaching of mathematics. several pieces of software have been developed that are aimed at improving the learning process. Geometry is a domain of knowledge which is particularly involved with the growing use of software in teaching. because of the important role played by external representations (usually called figures) and the new ways of handling these representations made possible by software specifically designed for geometry.Computers offer facilities not only for drawing in a faster and more precise way than in a paper and pencil environment. but also for moving or modifying figures, thus often enabling the user to visualize geometrical propellies easily. The questions that are addressed in this chapter deal with the changes introduced into teaching and learning processes by such software. These changes will be mainly discussed below in terms of i) the new status of geometrical figures as mediated by the computer and ii) the behaviour of students when performing tasks on the computer.
