Abstract

Abstract A device for teaching includes a work sheet having a number of sets of response regions. Each response region is comprised of at least one answer area and at least one confirmation area. Invisibly printed answers are generally provided within the confirmation areas. By omitting the answers from selected confirmation areas, it is possible to determine whether a student is making his response in the answer area before seeking a confirmation of the correctness of this answer by making the answer in the confirmation area visible.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 196 words
A device for teaching comprising, in combination: a sheet having a plurality of sets of response regions in serial order, each set including one answer area and one associated confirmation area, at least one of said answer areas comprising an instructive answer area including an invisible ink instructive pattern, the confirmation area associated with the instructive answer area having no visible or invisible ink printed information, at least one other of said answer areas comprising an instructive answer area not having an invisible ink instruction pattern, the confirmation area associated with said other answer area including an invisible ink information pattern; writing means for activation of said invisible ink and for recording a student response in said areas, whereby the student is to use the writing means to mark his response to each one of a number of serial questions in the associated answer area of the serial set of response regions, and subsequently is to verify his response only in the confirmation areas indicated; and a legend identifying each answer area instructive pattern and setting forth instructions for answer and response verification by reference to only the confirmation area having an invisible ink information pattern.
Claim 2
Independent Claim 196 words
A device for teaching comprising, in combination: a sheet having a plurality of sets of response regions in serial order, each set including one answer area and one associated confirmation area, at least one of said answer areas comprising an instructive answer area including an invisible ink instructive pattern, the confirmation area associated with the instructive answer area having no visible or invisible ink printed information, at least one other of said answer areas comprising an instructive answer area not having an invisible ink instruction pattern, the confirmation area associated with said other answer area including an invisible ink information pattern; writing means for activation of said invisible ink and for recording a student response in said areas, whereby the student is to use the writing means to mark his response to each one of a number of serial questions in the associated answer area of the serial set of response regions, and subsequently is to verify his response only in the confirmation areas indicated; and a legend identifying each answer area instructive pattern and setting forth instructions for answer and response verification by reference to only the confirmation area having an invisible ink information pattern.
Claim 3
Dependent Claim 22 words
The device of claim 1 including a plurality of answer areas for each set, each answer area of each set being identical.
Claim 4
Independent Claim 231 words
A method of teaching which generally provides immediate answer confirmation to the student and also encourages honest test procedures by the student, said method being one wherein correct answers are provided in invisible ink except in random instances, said method using means for activating the invisible ink, said means simultaneously providing a visible ink mark, said method comprising, in combination, the steps of: a. providing an answer sheet having a plurality of sets of visibly indicated response regions in serial order, each set including one answer area and one associated confirmation area; b. providing an invisible ink instructive pattern in at least one of the answer areas, the associated confirmation area not including invisible ink printing; c. providing at least one other answer area not having an invisible ink instructive pattern, the confirmation area associated with said other answer area including an invisible ink information pattern; d. providing a question for each set; e. providing a legend of answer areas which identifies the answer area instructive pattern and sets forth instructions for answer area response verification by reference to only the confirmation area having an invisible ink information pattern; and f. sequentially applying the means for activating to each answer area and subsequently to the associated confirmation area whenever no instructive pattern is made visible in the answer area whereby confirmation areas developed in improper sequence are immediately and permanently recorded.
