初中阶段是数学学习的黄金时期,我们初中数学教师应从起始年级(初一)开始,在教学中有意识、有计划地运用数学模型,帮助学生去思考、去探索数学知识,让学生能够摆脱思想束缚,释放出学习的智慧和解决问题的动力,从而提高数学学习的有效性.把实际问题转化为一个数学问题,通常称为数学模型.数学家布克(R.C.Buck)曾说:“模型化是数学中的一个基本概念,它处于所有数学应用之心脏,也处在某些最抽象
Junior high school is the golden age of mathematics learning, junior high school mathematics teachers should start from the beginning of grade (first), in the teaching of conscious and systematic use of mathematical models to help students to think, to explore mathematical knowledge, to enable students to get rid of ideas Bound to release the wisdom of learning and motivation to solve the problem, thereby enhancing the effectiveness of mathematical learning. The practical problems into a mathematical problem, commonly known as mathematical models .Buker (RCBuck) once said: ”model Chemistry is a basic concept in mathematics, it is in the heart of all mathematical applications, but also in some of the most abstract
