“物理建模”实验教学模式的教学实践——以“迈克尔孙干涉仪测量激光波长”实验为例

Teaching Practice on“Physics Modeling”Experimental Teaching Model——Taking the Experiment of“Michelson Interferometer Measuring Laser Wavelength”as an Example

在物理实验教学中发现,低年级本科生普遍缺乏物理建模思维,难以通过科学知识的建构历程获得对知识的深刻而全面的理解.为解决此问题,国防科技大学的大学物理实验课程以“物理建模”思想和“精益思想”创新教学模式,开展“物理建模”实验教学模式的教学设计,强化物理建模思维的培养.通过该教学模式在大学物理实验课程中的教学实践,以“迈克尔孙干涉仪测量激光波长”实验为例详细介绍“物理建模”实验教学模式的教学设计,为物理实验的教学改革提供借鉴.

In physics experimental teaching,it is found that junior undergraduates generally lack physical modeling thinking,they are difficult to obtain a profound and comprehensive understanding of knowledge through the construction process of scientific knowledge.In order to solve this problem,the physics experiment course of National University of Defense Technology innovates the teaching mode with the“physics modeling thinking”and“lean thinking”,and carries out the teaching design of“physical modeling”experimental teaching mode.Finally,it strengthens the training of students'physical modeling thinking.Based on the teaching practice of this teaching model,this paper takes the experiment of“Michelson interferometer measuring laser wavelength”as an example to introduce the teaching design of the experimental teaching model of“physics modeling”in detail,so as to provide reference for the teaching reform of physics experiment.
