函数是刻划事物运动规律的一种基本的数学模型,也是贯穿整个数学课程的脉络之一.一次函数是初中阶段函数学习的一个重要载体,各地每年中考试题中都会有关于一次函数及其应用的考查.笔者选取了几道有代表性的一次函数试题,对它们进行比较分析,发现一次函数试题的命制过程中有许多值得商榷的问题:一、试题的编制在逻辑上存在问题;二、存在与生活实际不符的情形.由 Function is a basic mathematics model which scored the law of motion of things, which is also one of the contexts that runs through the whole mathematics course.A primary function is an important carrier of function learning in junior middle school. Every year in the middle school exam questions, The author chooses a few representative primary function test questions, carries on the comparative analysis to them and finds that there are many questions that are worth discussing in the life process of a function test question: First, , There is a real life situation does not match
