Abstract
Abstract An instructional apparatus is disclosed comprising a holding frame having a grid of shallow and deep depressions or holes, the bottoms of which are defined by electrical contacts; a printed instructional format that contains circular response areas or zones that are precisely located over some of the shallow and deep depressions when the format is properly positioned on top of the holding frame; an electroconductive stylus with a cone shaped tip; a punching sheet that is sandwiched between the printed format and the holding frame and that obscures the depth of the underlying shallow and deep depressions from the student; and the necessary electrical components and connections to register and indicate when the tip of the stylus completes an electrical circuit by contacting the electroconductive contact material in the bottom of each shallow and deep depression. Electrical circuits are thereby closed at two different depths, one depth indicating correctness of response and the other depth indicating incorrectness of response. With this invention, multiple types of feedback are attained by activating different electrical components, plus the cone shaped tip of the stylus produces small and large holes in the punching sheet at the selected response areas depending on its depth of penetration.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
An instructional apparatus comprising: an instructional sheet having zones thereon indicating at least two types of answer choices, correct and incorrect, a holding mechanism provided with an upper surface for receiving said sheet, said mechanism having structure presenting said surface and defining relatively shallow and deep holes therethrough representing said types of answer choices, and further having means engageable with said sheet for holding the same on said surface in overlying relationship thereto with said zones in alignment with corresponding holes, said structure having electrical contact means in the bottoms of said shallow and deep holes, a stylus for selecting zones representing a student's answer choices, and provided with an electroconductive end portion engageable with the contact means in the hole corresponding to each zone selected upon insertion of said end portion thereinto, and circuit means connected to said end portion and said contact means for communicating the types of responses of a student to electrical information handling apparatus for processing and feedback.
Claim 2
Dependent Claim
163 words
An instructional apparatus comprising: an instructional sheet having zones thereon indicating at least two types of answer choices, correct and incorrect, a holding mechanism provided with an upper surface for receiving said sheet, said mechanism having structure presenting said surface and defining relatively shallow and deep holes therethrough representing said types of answer choices, and further having means engageable with said sheet for holding the same on said surface in overlying relationship thereto with said zones in alignment with corresponding holes, said structure having electrical contact means in the bottoms of said shallow and deep holes, a stylus for selecting zones representing a student's answer choices, and provided with an electroconductive end portion engageable with the contact means in the hole corresponding to each zone selected upon insertion of said end portion thereinto, and circuit means connected to said end portion and said contact means for communicating the types of responses of a student to electrical information handling apparatus for processing and feedback.
Claim 3
Dependent Claim
45 words
The instructional apparatus as claimed in claim 1, wherein said contact means comprises contact elements defining the bottoms of corresponding holes, and wherein said stylus has a tip, presenting said conductive end portion, engageable with the element in the hole corresponding to the selected zone.
Claim 4
Dependent Claim
58 words
The instructional apparatus as claimed in claim 2, wherein said tip is tapered and said zones have sheet material therein through which said tip is punched in making a selection, whereby the size of each hole punched in said sheet material depends on the depth of the corresponding hole in said structure into which the stylus is inserted.
Claim 5
Dependent Claim
62 words
The instructional apparatus as claimed in claim 1, wherein said structure includes a base member presenting said upper surface and having depressions therein defining said shallow holes, said member further having means depending therefrom defining cavitites communicating with said surface to present said deep holes, and wherein said contact means comprises an individual contact element in each of said depressions and cavities.
Claim 6
Dependent Claim
38 words
The instructional apparatus as claimed in claim 4, wherein said member and cavity-defining means are electrically nonconductive, and wherein each of said contact elements comprises an electrically conductive insert in the bottom of the corresponding depression or cavity.
Claim 7
Dependent Claim
86 words
The instructional apparatus as claimed in claim 1, wherein said upper surface has a pattern of apertures therein, said structure comprising an upper, electrically conductive sheet member spaced beneath said surface and presenting the bottoms of said shallow holes, and a lower member spaced beneath said upper member and presenting the bottoms of said deep holes, said upper member having openings therethrough at the locations of said deep holes, and wherein said electrical contact means includes said upper member and conductive means on said lower member.
Claim 8
Dependent Claim
29 words
The instructional apparatus as claimed in claim 6, wherein said structure further comprises a first sheet of nonconductive material above said upper sheet member and presenting said apertured surface.
Claim 9
Dependent Claim
37 words
The instructional apparatus as claimed in claim 6, wherein said conductive means on said lower member includes individual contact elements thereon aligned with corresponding openings in said upper member for engagement by said stylus upon insertion therethrough.
