论文摘要
在物理学中使用数学意义，需要将物理概念知识与数学符号结合在一起。介绍性物理课程的学生经常为此而苦苦挣扎，但这是学习如何通过数学思考的重要组成部分。教学维度分析（DA）。弄清楚哪些测量结果结合在一起以创建象征数量，这是帮助他们学会欣赏这种差异的重要第一步。在本文中，我讨论了与学习维度分析相关的一些问题，并展示了一些我们可以修改指导以提供帮助的方法。本文是有关如何帮助学生发展学习数学在科学中所需的科学思维技能的系列之一。
Making meaning with math in physics requires blending physical conceptual knowledge with mathematical symbology. Students in introductory physics classes often struggle with this, but it is an essential component of learning how to think with math. Teaching dimensional analysis (DA). figuring out what measurements were combined to create a symbolic quantity, is a valuable first step in helping them learn to appreciate this difference. In this paper I discuss some of the issues associated with learning dimensional analysis and show some ways we can modify our instruction to help. This paper is one of a series on how to help students develop the scientific thinking skills required for learning to use math in science.
