由“落磁”实验引起的建模思考

Modeling Thinking Arising from the“Falling Magnet”Experiment

物理建模是“科学思维”的核心要素,也是评价一个学生核心素养高低的重要指标.从“落磁”实验出发,结合学生在选考中所犯的错误,针对准确建模和区别相似模型,提出在教学中的有效策略.

Modeling in physics is the core element of“scientific thinking”,and it is an important index to evaluate the level of a student′s core literacy.Starting from the experiment of“falling magnet”and combining with the mistakes made by students in the examination,this essay put forward effective strategies in teaching aiming at accurate modeling and distinguishing similar models.
