8课时讲完几何光学

TEACH GEOMETRICAL OPTICS IN 8 LESSONS

为了彻底改变传统的几何光学教学方法,笔者借助计算机辅助教学手段对多媒体课件、课堂讲授、课外作业、网上辅导等教学环节进行精心设计,在8课时之内让学生掌握成像系统的初步设计方法,既能计算物像关系,又能初步判断成像质量.学生的学习手段与方法有较大改变,学习工具从以纸笔为主变为以电脑为主,课外作业从以公式推导为主变为以电脑操作设计为主,学生的学习效率、知识应用能力大大提高.

In this paper, the teaching reform of geometrical optics is introduced. By employing the computer assistant instruction to elaborately create and design multimedia courseware, classroom teaching, homework and on-line study, an innovative 8 lessons teaching of geomet rical optics is proposed to revamp the traditional way. Within 8 lessons, students are able to master the preliminary design procedure of imaging systems. They can not only calculate the mathematical relationship between objects and images, but also judge the quality of imaging. The learning technique of students is greatly changed. Pens are replaced by computers as learning tools while formula derivation is replaced by computer programming as homework. The learning efficiency and knowledge application skill are both improved.
