摘要
比较了人教版、北京版和北师大版初中数学教材中"反比例函数"第一节内容与例习题编排的异同,认为教师在教学中应借助具体实例的分析加强学生对函数的理解,应注重函数的多种表示,加强对变量、运动、变化的体现与分析。
According to the people's education press, Beijing publishing house and the Beijing Normal University Publishing House of the math teaching in the "inverse proportion function" the first section comparison as a carrier, illustrate how with specific function of learning to promote students to understand the concept of function.
