数学是集严密性、逻辑性、精确性、创造性和想象力于一身的科学,教师在黑板上作图、证明、解题的过程本身就是一个不可缺少的教学示范过程。如何将信息技术与初中数学课程的有机整合,这是一个值得探索的课题。我在近几年的数学教学中,运用《几何画板》辅助数学教学,取得比较明显的效果。一、《几何画板》与初中数学教学整合的可行性1.《几何画板》的最大优点是在动态的变化过程中保持几何关系不变。中点就是中点,平行就保持平行,这给学生理解知识带来了很大的便利。2.《几何画板》集绘制图形、函数图像、动画、测量计算、文字输入、编辑为一体,为几何模型的构建提供了一
Mathematics is a science that combines rigor, logic, accuracy, creativity, and imagination. The process of teachers drawing, demonstrating, and solving problems on a blackboard is an indispensable teaching demonstration process. How to organically integrate information technology and junior high school mathematics curriculum is a subject worth exploring. In mathematics teaching in recent years, I have used the “Geometric Sketchpad” to assist in mathematics teaching and achieved more obvious results. I. Feasibility of the integration of Geometry Sketchpad and mathematics teaching in junior high school 1. The greatest advantage of Geometry Sketchpad is to keep the geometric relationship unchanged during dynamic changes. The middle point is the middle point, and the parallels are kept parallel. This brings great convenience to students in understanding knowledge. 2. “Geometric Sketchpad” is a set of graphics, function images, animation, measurement and calculation, text input, and editing.
