国外学生对机械波理解的研究

Stady On Understanding of Mechanics Waves about Foreign Scholars

通过对国外物理教育工作者关于学生对机械波理解的研究的介绍,概述在这些研究中所观察到的学生的困难,包括学生在波的传播(包括绳波和声波)、波的数学表述、波的叠加上的具体困难,了解学生对机械波基本概念的掌握情况,对我国的物理教学有一定的借鉴作用。

The present paper presents the research on students' understanding of mechanical Waves by foreign scholars. Their research shows that students have difficulty understanding the propagation of waves (string waves and sound waves) ,the mathematical description of waves and superposition , and that it is important to help students understand the basic concepts of mechanicl waves. Their research is helpful to our physics teaching.
