论文摘要
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，我们经常开始对具有高度简化或玩具模型的复杂系统进行分析。在介绍性的物理课程中，我们倾向于不发表评论或动机而使用它们。一些学生推断物理学与他们对现实世界的理解无关，而不愿意将物理学概念与数学符号的认知融合在一起，这对于使物理学意识至关重要。在本文中，我讨论了通常隐藏的障碍，这些障碍使我们的学生很难接受和理解玩具模型的价值，并提出了可以提供帮助的教学方法。
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.
