在数学教学中引导学生主动探究 ,培养他们的自主学习能力和创新能力 ,一个重要的方法 ,就是把现代信息技术作为数学学习的辅助工具 ,让学生从中动手操作 ,从直观、想象到发现、猜想 ,然后给出验证及理论证明 ,亲身探究知识的发生发展过程 .几何画板软件利用其强大的图形、图像 In mathematics teaching to guide students to actively explore and develop their independent learning ability and creative ability, an important method is to use modern information technology as an auxiliary tool for mathematics learning, allowing students to use hands-on operations, from intuition, imagination to discovery, conjecture , and then give verification and theoretical proofs to personally explore the process of knowledge development.
