Abstract pg,1 This apparatus is a simple manually operated selfinstructional and self-testing apparatus which has a plurality of holes or depressions of different sizes, shapes, and/or different depths in a solid flat surface; an answer sheet or question and answer sheet; and a stylus with a shaped tip. All question and answer sheets, or answer sheets contain indicator zones that correspond to the multiple choice, true false, or matching questions. In the usual operation of the apparatus answer sheets or question and answer sheets containing indicator zones are positioned on the upper surface of the flat solid structure that contains many specially constructed holes or depressions. When the question and answer sheets are correctly positioned all indicator zones are directly above a hole or depression. The holes or depressions are of several cross sectional sizes, shapes, and/or depths. The student pushes a stylus through the indicator zones he feels correspond to correct answers. The stylus used by the student to perforate the indicator zones of the question and answer sheet is of a special configuration. The stylus is so constructed that when it first penetrates the indicator zone it produces one shape of hole, and if the student is able to push it deeper, or manipulate it further, this first shape is transformed into a second shape, or into a second and then a third shape. The different hole sizes, shapes, and/or depths in the underlying solid surface are the determining factors that limit the depth to which the stylus can penetrate the indicator zone, or be further manipulated in the indicator zone. Thus the size, shape, or depth of the underlying hole or depression will determine what will be the final shape of the hole pattern produced at an indicator zone by manipulation of the stylus. The different shapes of holes produced in the indicator zones indicate the correctness, partial correctness, or incorrectness of the student''s responses.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
179 words
Educational apparatus comprising: an instructional sheet having zones thereon for indicating answers selected in response to questions; a plate member provided with a flat surface for receiving said sheet and having a number of holes therein of at least two different cross-sectional geometric shapes for indicating whether answers selected on said sheet are correct; means on said member for holding said sheet in overlying relationship with said surface in a predetermined position where said zones are aligned with certain of the holes in said surface in accordance with the answers represented by said zones; and a stylus having a blade-like tip for punching through selected zones into the holes therebeneath, all of said holes being configured to fully receive said tip upon insertion thereunto, said different shapes of holes permitting different degrees of rotation of said tip within each hole after full insertion of the tip thereinto, depending upon the hole corresponding to each selected zone, whereby the final shapes of the openings punched into said sheet after rotation of said stylus indicate the correctness of the selected answers.
