理论力学中容易混淆的概念的教学

本文根据自己多年的教学经验,提出在工科的理论力学教学中应十分重视概念的教学,特别是在一些容易混淆的概念上,应加大教学的力度.本文以力系简化、力系平衡、牵连速度、力矩等为例,说明在这些概念的教学中,应如何剖析其差异,探究其联系,最终设法使学生加深对概念的理解.使他们牢固掌握所学的概念和分析问题的方法,避免出现不该出现的错误.

The Teaching of Concept Witch Easy Mix up in Theoretical Mechanics

This paper points out we should pay attention to the teaching of concept on the basis teaching ex- perience,and points out we should pay special attention to these concept which easy mix up we should reinforced power.With the reduction of fore system,implicate velocity,moment as example we explain teaching of concept.For these concept we emphasize their contact and distinguish.Through these efforts the students understand these concept better,they avoid unnecessary mistake.
