微分近似下的光学习题教学探讨

与物理学中的其他内容相比,光学教学中经常会出现近似条件及近似计算的情况,同时光学问题的研究特点也与其他问题不同,学生往往在学习过程中忽视应用数学结论的使用条件.实际上,正确地理解物理基本概念及其数学本质,是分析和理解有关光学现象的关键所在.因此,光学教学中不仅要强化基本概念和基本规律,还要结合现代化的教学手段,充分掌握数学结论在光学教学中的应用.

Investigation of optical exercises teaching based on differential approximation

Compared with other contents in physics,approximate condition and calculation are used more often in optics teaching. At the same time,the characteristics of the optical problem are different from other problems. So students tend to neglect the conditions of mathematical results in the learning process. In fact,the correct understanding of natural concept of physics and mathematics is the key to learning of optical phenomena.Therefore, optics teaching should not only strengthen basic concept and law, but also put emphasize on combining the computer software and optics.
