Limit,derivative,and integral were the three important core concept of single variable calcu-lus,which is essentially a mathematics thought method of state from static to dynamic.Mathematical concepts were generated from practical problem,which had a rich background process,but the results were always ab-stract mathematical logic formula.In this paper,three concepts teaching and how to improve students'applica-tion consciousness and ability were discussed.%极限、导数、积分是一元微积分中三个重要核心概念,本质上是一种从静态到动态的数学逼近思想方法。数学概念产生于实际问题,有丰富过程背景,但结果往往为抽象的数学逻辑结构式。探讨了三个概念教学及如何提高学生的应用意识和应用能力。
