教学工作是一项复杂、细致又具有高度科学性和艺术性的工作,必须加强教学研究。不断进行改革,才能不断提高教学质量。下面只就理论力学中运动学教学谈谈自己的体会。一、引导预习,培养自学能力“授人以鱼,只供一饭之需;教人以渔,则终身受用无穷。”随着科学技术的迅猛发展,培养学生自学能力就更显重要。所以在教学中,怎样引导学生预习,已列入备课中的一个重要部份。如在讲刚体平面运动的基点法之后,根据基点法求平面图形上点的速度必须都要由两个速度矢合成,显然很不方便,如果能取速度等于零的点作为基点,那问题就简单多了。于是提出一个问题:在某瞬时图形上是否有一点的速度等于零?以 Teaching work is a complex, meticulous and highly scientific and artistic work that must be strengthened. Continuous reforms can continuously improve the quality of teaching. In the following, I will talk about my own understanding of kinematics teaching in theoretical mechanics. First, guide preparations, training self-study ability “to teach people to fish, only for the needs of a meal; teach people to fish, then life is boundless.” With the rapid development of science and technology, the ability to develop students’ self-learning is even more important. Therefore, in the teaching, how to guide students to prepare for preview has been included in an important part of lesson preparation. For example, after calculating the basis point method of the rigid body plane motion, the speed of the point on the plane figure according to the base point method must be composed of two velocity vectors. Obviously it is inconvenient. If we can take the point where the velocity is equal to zero as the base point, the problem is much simpler. Now. So the question was asked: Is there a point in the instantaneous graph that has a speed equal to zero?
