用“小步子”教学法学习数列极限概念

Study on Limit of Sequence conceptin With "A Little Pace" Teaching Method

极限概念是《高等数学》最基本的概念之一,理解、掌握极限概念对于学习微积分至关重要。用“小步子”教学方法,首先给出数列极限的描述性定义,然后逐步加以分析、改进,最终得出精确的数学定义,有利于学生对概念实质的理解和掌握。

The concept about limit of sequence is higher mathematics of the most fundamental conceptions . Understanding , mastering the concept about limit is utter important to learn calculus . With the help of teaching method 'a little pace' , descriptive definition of limit is given firstly , and then analyse , improve it and obtain an exact mathematics definition . This is useful for students to understand and master nature of the conception.
