Abstract
An instructional device is disclosed herein having a booklet containing a series of sheets displaying questions, selectable answers and clues taking the form of pictorial, graphic and alpha/numeric characters. The selectable answers are displays of specific graphic forms and these graphic forms are repeated in seemingly random arrangement on an answer area of the sheet which includes an index mark. A separate decoder is provided having a case with open windows adapted to visually display underlying graphic forms from the answer area for visual comparison with selected graphic forms entered by the user into the decoder via movable members carrying graphic forms wherein the selected graphic forms on the movable members appear adjacent to windows with the correct answer association.
