数学在物理学中的应用1. Dimensional analysis

Using math in physics -- 1. Dimensional analysis

Edward F. Redish

摘要:

在物理学中用数学创造意义需要将物理概念知识与数学符号学相结合。在物理学入门课上,学生们经常会遇到这个问题,但这是学习如何用数学思考的重要组成部分。弄清楚什么样的测量组合起来创造一个象征性的数量,是帮助他们学会欣赏这种差异的有价值的第一步。在本文中,我讨论了与学习量纲分析相关的一些问题,并展示了一些我们可以修改教学以提供帮助的方法。本文是关于如何帮助学生发展学习在科学中使用数学所需的科学思维技能的系列文章之一。

英文摘要:

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.
