几何画板在中学数学教学中的应用

Application of Geometer Sketchpad for Mathematical Teaching in Middle School

多媒体技术的应用为数学教学的更新创造了条件，也给学校教育带来了一场深刻的变革。数学作为一门独立的自然科学，有它自身的特点、体系和规律，而几何画板作为电子尺规，是研究几何图形的关系、动态地观察几何图形运动状态、探索数学信息的有力工具。从几何画板辅助中学数学教学的现状、目标及其意义入手，结合几何画板辅助中学数学教学的实例，就几何画板在中学数学教学中的应用及其在教学活动中的重要作用做了系统地阐述和说明。

The application of multimedia technology not only provides good condition for mathematic teaching, but also brings a profound change to school education. As an independent natural science, mathematics has its own characteristics, system and regulars. Whereas, as the e-Ruler, the geometer＇s sketchpad is a powerful tool to study geometry relationships, observes geometry movement and explores mathematical information. With the examples of geometer sketchpad used in secondary school mathematic teaching, and dwelling upon its status, objectives and significance, the author well specifies how to apply the geometer＇s sketchpad into mathematics teaching and thoroughly illustrates its importance in teaching activities.
