运动学是理论力学的三大教学内容之一,是后续课程如机械原理的重要基础,如何在有限的教学时间内教好该内容值得任课教师思考.本文从运动学与大学物理相关知识点的联系与区别出发,指出运动学部分的教学应分清主次,合理安排教学学时.同时,重点针对点的合成运动,对"动点"、"动系"的概念及其选择方法进行了探讨,指出了教学中应补充完善的内容,强调了思维方式的改变和对学生创新能力、解决实际问题能力的培养.

Focusing on the two types of problems related to transmission mechanism in contact movement during the analy-sis of the composite motion of a point, the paper pointed out the limitation of the analysis method to the second common prob-lems mentioned above based on the analysis of their characteristics and solving method. Therefore, the paper designed an un-conventional type of transmission mechanism problems in contact movement and analyzed its solving method. The paper put forwarded the idea that the prevailing analysis methods are not suitable for the analysis of unconventional problems. If it is our intention to solve this type of problems more effectively, innovations should be made on the analysis method and idea, breaking through the conventional recognition to the selection method of moving point and moving reference system. In ter-ms of the analysis method to unconventional problems, the paper emphasized the flexibility to the selection of the moving reference system, which is of significance to the enrichment of the solving methods to the composite motion and improvement on the students' abilities to analyze and solve problems.
