Intermediate States and Powerful Ideas: Learning about Image Formation.
Goldberg, Fred; Bendall, Sharon
This paper describes a curriculum unit developed in the domain of geometrical optics which has been incorporated into an activity-based physics course for prospective elementary teachers. The instructional goal was to help students develop a set of powerful ideas that could be applied both verbally and diagrammatically to account for optical phenomena encountered in daily experience. Students engage in extensive talking, writing, and thinking about the phenomena. Two separate sections summarize research on student understanding of geometrical optics and briefly describe the view of the learner that guided the curriculum development. Following this, a section describes the set of powerful ideas that comprises the conceptual model for geometrical optics developed during the unit and how an interactive multimedia program is used. Finally, an evaluation of the effectiveness of the unit is discussed. Contains 28 references. (MKR)
