基于GeoGebra軟件的矩陣乘法的可視化教學(xué)研究
摘 要:在線性代數(shù)的教學(xué)中,矩陣乘法是一個(gè)非常重要的算法,矩陣乘法的一個(gè)應(yīng)用就是旋轉(zhuǎn)變換,本文借助GeoGebra可視化功能,動態(tài)展示了旋轉(zhuǎn)變換的效果,使矩陣乘法的本質(zhì)得到展示,加深學(xué)員對矩陣乘法的理解,同時(shí)也增加了課堂的活躍性與趣味性,有助于提高教學(xué)效果。

Abstract: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.
Keywords:GeoGebra;Multiplication;Visualization
