Abstract | An effective way to teach the concept of image is to give students a model of human vision which incorporates a simple mechanism of depth perception. In this study two almost identical versions of a curriculum in geometrical optics were created. One used a mechanistic, interpretive eye model, and in the other the eye was modeled as a passive, black-box receiver of light. These curricula were used with two treatment groups (N=28) of students from an ethnically diverse public school, which were balanced for gender, mathematics class completed, and self-reported grades in mathematics and science. It was concluded that the study demonstrated the gains to be made by teaching students a perception-based model of image formation rather than a more traditional geometrical definition of image formation. In particular, students who were taught a mechanistic model of visual perception exhibited a better understanding of the notoriously difficult relationship between an observer and a virtual image. They were also better able to identify the location of an image in a range of real-world optical situations, and were less likely to think of it as located on the surface of a mirror or lens. (JRH) |
