《初中数学课程标准》指出:“在呈现作为知识与技能的数学结果的同时,重视学生已有的经验,使学生体验从实际背景中抽象出数学问题、构建数学模型、寻求结果、解决问题的过程.”根据《课标》编写的苏科版数学教材设计了一些“数学建模”活动,我们要充分开展和利用这些活动,并以此来调动学生学习数学的积极性,激发他们学习数学的热情.当然,关于“两点之间,线段最短”的建模应用,很多老师、专家学者都写了大量的文章来论述.笔者不揣固陋,也想谈谈
“Junior high school mathematics curriculum standards,” pointed out: “in the presentation of mathematics as a result of knowledge and skills at the same time, emphasis on the existing experience of students so that students experience abstraction from the actual background of mathematical problems, building mathematical models, finding results and solving problems . ”Based on the textbook“ Su Curriculum ”written by the“ Standard ”designed some“ mathematical modeling ”activities, we should fully carry out and use of these activities, and in order to mobilize the enthusiasm of students to learn mathematics to stimulate Of course, many teachers and experts and scholars have written a lot of articles about the modeling application of “the shortest line between two points”, and I would like to talk about it
