| 摘要: |
| 多数“线性代数”教材都是从排列的概念和性质引入行列式，按照这一顺序组织教学，教员需大量时间讨论排列的相关知识，学员容易忽视行列式计算的重要性.针对行列式教学中的常见问题，从展开角度讨论了行列式有关性质的证明，并分析了教学实施的具体效果. |

| Abstract: |
| Most linear algebra textbooks introduce determinant from the definition and the properties of permutation.It take lots of time for teachers to explain the knowledge of permutation and it is easy for students to ignore the importance of determinant computation.Aiming at such problems in determinant teaching，some properties are proved from the expanding along determinant row (column) and some teaching effects are given in this paper. |
| Key words: linear algebra determinant expanding properties |
