摘要
《线性代数》教学改革一直备受关注.本文从三个方面对教学内容改革进行研究.首先,分析了各章节之间的联系,从工程实践本质上明确本课程的教学主线;其次,重新编排了教学内容,突出了教学主线意识,成功解决了矩阵求逆的初等变换法的位置滞后问题;最后,对向量组的线性相关性教学内容的改革进行了探索.该工作确保了理论教学体系,合理减少了理论描述,降解了教学难点,有效地压缩了教学时数,较好地适应了现代教学环境.
Teaching reform of linear algebra is being greatly concerned all these years.A teaching content reform is discussed from three aspects in this paper.Firstly,relationship among all parts is analyzed,and essential techinical main teaching line clears up.Secondly,teaching content is rearranged,which leads the sense of main teaching line stand out,and the problem of elementary transformation method of matrix inversion introduced delay is moved successfully.Finally,a research on the teaching content reform of vector group linear correlation is made,by which,system of theory is held on,theory description is diminished,and the difficulty in teaching is pulled down.So teaching time is compressed efficiently,which adapts our modern teaching situation greatly.
