在物理学中使用数学-- 4.玩具模型
Using math in physics -- 4. Toy models
摘要：
学习创建、使用和评估模型是成为科学家的核心要素。在物理学中，我们经常从高度简化的模型或玩具模型开始分析一个复杂系统。在物理入门课上，我们倾向于不加评论或动机地使用它们。一些学生推断物理学与他们对现实世界的理解无关，并且不鼓励将物理概念与数学符号的认知融合对于理解物理学至关重要。在本文中，我讨论了经常隐藏的障碍，使我们的学生难以接受和理解的玩具模型的价值，并建议教学方法，可以帮助。
英文摘要：
Learning to create, use, and evaluate models is a central element of becoming a scientist. In physics, we often begin an analysis of a complex system with highly simplified or toy models. In introductory physics classes, we tend to use them without comment or motivation. Some students infer that physics is irrelevant to their understanding of the real world and are discouraged from making the cognitive blend of physics concepts with math symbology essential for making sense of physics. In this paper, I discuss the often hidden barriers that make it difficult for our students to accept and understand the value of toy models, and suggest instructional approaches that can help.
