ABSTRACT:
Instructional apparatus of two parts to be used in conjunction with previously patented instructional apparatus, U.S. Pat. Nos. 3,902,255, 3,964,176, and 4,065,858, which have a grid of depressions of two or more different depths. The first part of this invention is a sheet of material that contains a series of pre-punched holes that correspond to some of the shallow and deep depressions when this sheet of material is precisely positioned on the upper surface of the grid of underlying depressions. The first part of this invention provides a "blank" sheet that has a minimum of printing on its upper surface, this "blank" sheet has a pattern of pre-punched holes that correspond to correct or incorrect responses. The second part of this invention is a printed sheet that has printed large dots or other indicating means, that when accurately alligned and positioned under the first part reveal which of the holes in the first part correspond to correct responses, and which holes correspond to incorrect responses. This allows an instructor to rapidly and conveniently prepare their own instructional formats that provide the student with immediate feedback in the manner described in the above noted patents. The instructor may type, print, draw, or use other graphic means to illustrate the question, and give a choice of answers.
