【摘要】 演示实验是增强振动与声基础理论授课效果的有效辅助教学方法。演示实验把振动与声的规律和现象直观地对学生进行展现,增强学生对理论知识的理解,同时吸引学生注意力,活跃课堂气氛。遵循针对性、直观性、可靠性、安全性和启发性的原则进行演示实验设计,采用合理的实施方法在理论授课过程中进行实验演示,达到增强振动与声基础理论课程授课效果的目的。更多还原

【Abstract】 Demonstration experiment is an effective assistant teachingmethod to improve the teaching effect of Foundation of Sound andVibration.Demonstration experiments show the laws and phenomenaof vibration and acoustics intuitively,and enhance students’ under-standing of theoretical knowledge.At the same time,it attracts stu-dents’ attention and can activate classroom atmosphere.Following the principles of pertinence,intuition,reliability,safety and enligh-tenment,the design of demonstration experiment should be carried out.In order to improve the teaching effect of Foundation of Sound and Vibration,the demonstration experiment is carried out in thecourse of theoretical teaching by reasonable implementation method.更多还原
