信息技术的发展改变了数学世界。数学与信息技术的相互促进与紧密结合,不仅形成了作为高新技术的核心成分和工具库的数学技术,也深刻地改变了数学的教和学的方式。在利用信息技术创设的数学学习环境中,操作、观察、试验、猜想、发现等过程变得具体而清晰,数学思维的目的性增强, The development of information technology has changed the world of mathematics. The mutual promotion and close integration of mathematics and information technology has not only formed mathematical techniques as a core component and tool library for high-tech, but also profoundly changed the way mathematics teaches and learns. In the mathematics learning environment created using information technology, the processes of operation, observation, experimentation, conjecture, discovery, etc. become concrete and clear, and the purpose of mathematical thinking is enhanced.
