摘　　要：微课的本质是通过对一个知识点的教学过程进行充分的设计,以“短而全、简而精”的形式呈现给学习者.基于线性代数抽象、难懂的特点,以《向量组的最大线性无关组与秩》的微课设计为例,通过理论与具体设计思路的阐述,分析探讨“如何对线性代数进行微课设计”,以浅显易懂的形式呈现给学习者,进而实现高效教学.The essence of the micro-course is to present to the learner a teaching process of knowledge by a"short but complete,simple but exquisite"method.Since the abstraction and incomprehensibility of linear algebra,in this paper we will design a micro-course entitled the largest linearly independent group of vector groups and its rank,as an example to illustrate the theory and specific design ideas,which will show that how to design the micro-course for linear algebra.By presenting Easy-to-understand teaching method to learners,we can realize the efficient teaching process.

关 键 词：线性代数 微课设计 向量组的最大无关组 向量组的秩
