ABSTRACT:
A modular device for use in educational institutions comprising a housing having opposed, spaced, parallel walls or panels. The first panel which faces the student, has a rectangular cutout area within which is mounted a generally disc-shaped member, rotatable about an axial pin which is secured at both ends to said rectangular cutout area. The disc-shaped member bears two or more response tabs on its viewing surface which are registerable with a viewing area cut out in the other panel which faces the instructor. The first panel also includes a horizontal slot, and a lever is mounted in said slot, which lever is connected to a shutter means to open and close the viewing area in the second panel. A tally counter may be optionally installed on the first panel to count the number of questions to which responses have been provided.
