基于GeoGebra软件的矩阵乘法的可视化教学研究

在线性代数的教学中,矩阵乘法是一个非常重要的算法,矩阵乘法的一个应用就是旋转变换,本文借助GeoGebra可视化功能,动态展示了旋转变换的效果,使矩阵乘法的本质得到展示,加深学员对矩阵乘法的理解,同时也增加了课堂的活跃性与趣味性,有助于提高教学效果。

In the teaching of linear algebra,matrix multiplication is a very important algorithm.One application of matrix multiplication is selection transformation.In this paper,with the help of GeoGebra's visualization function,the effect of rotation transformation is dynamically displayed,so that the essence of matrix multiplication can be displayed,which can deepen the students'understanding of matrix multiplication,increase the activity and interest of the classroom,and help improve the teaching effect.
