Abstract
Abstract A self-educational device adapted to provide a programmed plan of instruction for teaching bidding in the game of contract bridge, said device being adapted to hold a plurality of cards representing a set to be studied. The device includes means for allowing incremental, selective and progressive exposure and study of data on said cards so as to firstly, incrementally provide a student with text material, secondly, present the student with the problems in an increasing order of complexity, thirdly, selectively present rationale to solutions so as to require restudy in the case of a wrong answer, fourthly, provide immediate self correction without distraction, fifthly, instill a logical approach to problem solution thereby teaching the student to think, sixthly, allow filing of the cards so as to make ready for immediate restudy, and seventhly, automatically provide a grading so that an instructor is able to readily determine which students are most in need of help.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
222 words
The combination comprising a casing, a plurality of cards in said casing, each of said cards being sufficiently rigid so as to self sustain in a plane, said casing having a first and second apertures therein, each of said cards including first areas aligned with said first aperture and second areas aligned with said second aperture, each of said cards having indicia providing an interrogatory in said first area, each of said cards having indicia providing the answer to said interrogatory in said second area, each of said cards having indicia representing the rationale for said answer in said third area thereof, one of said apertures normally exposing the first area of the top card of said plurality of cards, the other of said apertures including a coVer member normally covering said second area on said top card, means for (1) displacably mounting said cover so as to expose said answer while concealing said rationale, and (2) for exposing both said answer and said rationale, and means for allowing individual and successive removal of the top card of said plurality of cards and reinsertion thereof as a bottom card to said plurality of cards to maintain said plurality of cards in a predetermined order so as to incrementally present a student with interrogatories of increasing complexity as he proceeds to subject mastery.
Claim 2
Dependent Claim
222 words
The combination comprising a casing, a plurality of cards in said casing, each of said cards being sufficiently rigid so as to self sustain in a plane, said casing having a first and second apertures therein, each of said cards including first areas aligned with said first aperture and second areas aligned with said second aperture, each of said cards having indicia providing an interrogatory in said first area, each of said cards having indicia providing the answer to said interrogatory in said second area, each of said cards having indicia representing the rationale for said answer in said third area thereof, one of said apertures normally exposing the first area of the top card of said plurality of cards, the other of said apertures including a coVer member normally covering said second area on said top card, means for (1) displacably mounting said cover so as to expose said answer while concealing said rationale, and (2) for exposing both said answer and said rationale, and means for allowing individual and successive removal of the top card of said plurality of cards and reinsertion thereof as a bottom card to said plurality of cards to maintain said plurality of cards in a predetermined order so as to incrementally present a student with interrogatories of increasing complexity as he proceeds to subject mastery.
Claim 3
Dependent Claim
62 words
The combination as defined by claim 1, each of the cards including a third area aligned with and normally exposed through said other of said apertures, selected ones of said cards having text material in said third area to provide background in answering the interrogatory presented on subsequent cards whereby text material is incrementally presented with intermediate testing on the text increments.
Claim 4
Dependent Claim
49 words
The combination as defined by claim 1, said pair of apertures being located in the top well of said casing, said apertures being adjacent so as to provide immediate self correction, said top wall being recessed thereby providing a slot for individually grasping the top card for removal purposes.
Claim 5
Dependent Claim
48 words
The combination as defined by claim 1, each of said cards including indicia indicating the order of said cards in said predetermined order, said casing including an aperture for exposing said last-mentioned indicia whereby an instructor is made immediately aware of a student''s progress relative to other students.
Claim 6
Dependent Claim
73 words
The combination as defined by claim 1, said plurality of cards being arranged in a stack with interrogatories relating to a general problem area, each of said cards including indicia indicating a particular problem area of the more general problem area, said plurality of cards being arranged in an order so that the particular problems are presented in a logical order thereby teaching the student how to think in solving the general problem.
Claim 7
Dependent Claim
50 words
The combination as defined by claim 1, each of said cards including a recess, said casing including locating means cooperating with said recess for assuring alignment of said interrogatories and said answers with said aperture and for minimizing shift of said plurality of cards as the top card is removed.
Claim 8
Dependent Claim
39 words
The combination as defined by claim 1, means including a reentry slot for allowing reinsertion of a removed card to the bottom of said plurality of cards, said cards being sufficiently rigid so as not to flex on reinsertion.
Claim 9
Dependent Claim
23 words
The combination as defined by claim 7, means for maintaining said plurality of cards in a raised position relative to said reentry slot.
Claim 10
Dependent Claim
22 words
The combination as defined by claim 8, ramp means for guiding a reinserted card to the bottom of said plurality of cards.
Claim 11
Dependent Claim
119 words
The combination comprising a casing, a card in said casing, said card having indicia providing an interrogatory in a first area thereof, said card having indicia providing an answer to said interrogatory in a second area thereof, said card having indicia representing the rationale for said answer in a third area thereof, said casing including means for exposing said interrogatory, said casing including further means for (1) selectively exposing said answer while concealing said rationale so as to allow a student to restudy a problem answered incorrectly, and (2) for exposing both said answer and said rationale, said further means includes aperture means in said casing aligned with said second and third areas, cover means for said aperture means.
