数学模型是对部分现实世界,为了一种特定目的而作的一个抽象、简化的结构.这个结构是用字母、数字及其他数学符号建立起来的,用于描述客观事物的特征及其内在联系.数学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,在初中数学教育阶段,引导学生进行建模训练对学生的心智发展尤为重要.本文通过剖析一个课堂教学案例来说明如何运用模型思想开展教学.一、教学案例(一)引入新知 A mathematical model is an abstract and simplified structure for a part of the real world, for a specific purpose, which is constructed from letters, numbers and other mathematical symbols to describe the characteristics of the objective things and their internal relations. The establishment of mathematical model is the basic way for students to understand and understand the connection between mathematics and the outside world.It is particularly important for students to develop mental training in the junior high school mathematics education stage.This paper illustrates how to use a classroom teaching case Model ideas to carry out teaching. First, the teaching case (a) the introduction of new knowledge
