An unusual concept in the teaching of elementary geometric optics has been developed, based on a comprehensive system of carefully prepared, closely integrated visual teaching aids. The basis of the system is a building up in overlays of the individual figure which retains the precision usually associated only with conventional single-layer illustration.
Before presenting the figure to the students, the instructor breaks the figure down into meaningful fragments and then constructs the figure in class by introducing its concepts in a sequence of overlays. The materials are uniform in their style, execution, and orientation, to allow interchangeability without confusion.
