本文介绍了一个调查学生的理解几何光学，并说明了使用的研究作为基础的课程开发。有证据表明，大学生谁学习过物理学的入门级和超越往往不能应用几何光学的基本概念，占屏幕上产生的图案时，光圈或障碍物被放置在光源和屏幕之间。识别和分析学生的困难指导了教程的初步设计，以补充在一个典型的微积分或代数为基础的课程教学。同时，还为学前教师制定了一个以实验室为基础、以探究为导向的课程。持续评估是课程编制过程的一个组成部分。从这一反复循环演变而来的教学材料已证明对目标人群有效。
This article describes an investigation of student understanding of geometrical optics and illustrates the use of research as a basis for the development of curriculum. Evidence is presented that university students who have studied physics at the introductory level and beyond often cannot apply basic concepts from geometrical optics to account for the pattern produced on a screen when an aperture or obstacle is placed between a light source and the screen. Identification and analysis of student difficulties guided the initial design of a tutorial to supplement instruction in a typical calculus-based or algebra-based course. Development of a laboratory-based, inquiry-oriented curriculum for precollege teachers took place concurrently. Ongoing assessment was an integral part of the curriculum development process. The instructional materials that evolved from this iterative cycle have proved to be effective with the target populations.
