论文摘要
学习在科学中使用数学是一项非平凡的任务。它涉及许多不同的技能（通常不在数学课中教授），这些技能有助于将物理知识与数学符号结合在一起。其中之一是量化的想法：可以将物理量分配为特定数字。第二是开发规模的直觉。帮助学生发展这些技能的一种方法是教授估计：考虑物理状况并将合理近似数字提交的能力
Learning to use math in science is a non-trivial task. It involves many different skills (not usually taught in a math class) that help blend physical knowledge with mathematical symbology. One of these is the idea of quantification: that physical quantities can be assigned specific numbers. A second is to develop an intuition for scale. One way to help students develop these skills is to teach estimation: the ability to consider a physical situation and put reasonable approximate numbers to it
