模型思想的建立是学生体会和理解数学与外部世界联系的基本途径。培养模型思想的基本活动就是建立模型。教师要重视在教学中培养学生的模型思想,培养学生的数学应用意识。学生的思维经历从直观到抽象的过程,有助于发展学生的模型思想;有机抓住情境创设,引导学生从情境中抽象出数学问题,以建模为核心,培养学生运用知识解决问题的能力。 The establishment of model thinking is the basic way for students to understand and understand the connection between mathematics and the outside world. The basic activity in cultivating the model idea is to set up the model. Teachers should pay attention to cultivating students ’model thinking in teaching and cultivating students’ awareness of mathematical application. Students experience from intuitive to abstract process, help to develop the student’s model idea; organic seize the situation to create, to guide students to abstraction from the situation of mathematical problems, modeling as the core, to develop students ability to use knowledge to solve problems .
