Student-sensitive teaching at the tertiary level: a case study

Transparency display devices to display bound books of transparencies include a translucent screen mounted in a frame which is at a substantial angle to the horizontal plane when the translucent screen is arranged for viewing. A light source is provided behind the translucent screen and a transparency book support is arranged to oscillate to and from proximity with a margin of the screen to facilitate the removal of transparencies from viewing position to storage position. Two modifications of this support are shown, which respectively oscillate and reciprocate. Two support cabinets include one capable of being folded into a relatively flat package for transportation, and one permanent cabinet having storage for the transparencies in the form of tracks to receive the ring binder portion of the book while allowing the transparencies to hang in a protected place.
