兼顾理论与实践的机械振动基础课程教学模式探索

针对目前机械振动基础课程教学中存在的学生学习积极性不高、理论与实践脱节等问题,文章详细对比分析了常用教学方法的特点,并探讨提出ETHCP教学模式,在每节课程中将实验演示、理论推导、历史简述、案例分析和课堂练习有机结合,并通过具体教学案例论述了ETHCP实施过程。教学实践表明,ETHCP可以有效提高学生学习兴趣,并且多数学生对工程中的振动问题可以提出有效的解决思路。

It is often reported that the during the course of Fundamentals of Mechanical Vibration,the learning initiative of the students are relatively low because of the disconnection between theory and practice.Aiming at this issue,we reviewed the existing teaching methods and proposed the ETHCP(Experiment-Theory-History-Case-Practice)model of teaching.The basic idea is to incorporate experimental demonstration,theoretical derivation,history introduction,case analyzing,and in-class practice in the teaching of each knowledge point.The specific procedure of ETHCP approach is presented by an example concerning the Rayleigh's approach of modelling the vibration systems.Our teaching practice in Beihang University shows that ETHCP can effectively trigger the curiosity of the students and therefore improve the degree of concentration.We also observed that the students are more confident to use the basic knowledge of vibration to interpret and solve the engineering problems when they are taught by the ETHCP approach.
