1.架构起数学与生活的“观察”之桥生活中的数学问题具有形象性和启发性,它能唤醒学生已有的知识经验,增强学习动机和学习信心,不仅有助于引导学生进入数学情境,也有利于学生思维的发展。如我在教学“两点之间,线段最短”这一节时,我问学生:公园里四四方方的草坪为什么总是被踩去四个角?其实这个理由很简单,因为人们走路总爱走捷径,在不知不觉中运用了“两点之间,线段最短”这一知识点。 1. Architecture Mathematica and life’s “bridge of observation” The mathematical problems in life are vivid and inspiring. They can arouse students’ existing knowledge and experience, enhance their motivation and learn confidence, which not only helps to guide students Into the mathematical situation, but also conducive to the development of student thinking. When I was teaching “the shortest line segment between two points”, I asked the students: Why is the box office lawn in the park always being traversed to the four corners? In fact, the reason is very simple because people Walking always love to take shortcuts, unwittingly used “between two points, the shortest line ” this knowledge point.
