新课程标准要求“经历从具体情境中感知数学,并抽象出符号语言”,引导同学们建构数学模型,培养学习兴趣,然而一些问题情境对初学者来说,分析、理解比较困难,现就一元一次方程中列方程解应用题为例,用列表法帮助分析列方程,供同学们参考。一、行程问题例1电动机车和磁悬浮列车从 The new curriculum standards require “experience the perception of mathematics from specific contexts and abstract the symbolic language” to guide the students in constructing mathematical models and foster interest in learning. However, some problem situations are difficult for beginners to analyze and understand. The equations in the equations in the first equation are used as an example. The list method is used to help analyze the equations for the students to refer to. First, trip problem Example 1 from the motor car and maglev train
