Abstract:
A method is provided for creating a foundational instructional design model for shareable content object (SCO) by pre-defining a semantically structured reusable learning type (RLT), and joining individual or repeated RLT's with sequence or choice indicators to form an instructional design model. The instructional design model is itself a semantically structured document that can be used and reused to create SCOs.

Abstract:
Applications of photoerasable colorant composition include photoerasable price markings for pricing goods, documents such as gaming tickets for securely communicating concealed information, photoerasable paint for temporary markings on terrain and structures such as signs, roadways, trees, and buildings, marking instruments such as pens, and wick or felt markers, ultraviolet light exposure indicators, and dry printing. The photoerasable or mutable colorant composition comprises a mutable colorant and an ultraviolet radiation transorber which, upon irradiation with ultraviolet radiation, interacts with the colorant to irreversibly mutate the colorant and thereby render the colorant substantially colorless. The mutable colorant composition may also include a molecular includant.

Abstract:
A learning device comprises a receptacle for holding an information bearing card. The information bearing cards include a problem and a coded answer. The receptacle of the learning device includes a decoding display window with a movable writing screen which may be moved to cover or uncover the decoding display window. The user can insert the information bearing cards into the receptacle, write down a response on the writing screen with the display window covered, and compare their response with the correct answer by moving the movable writing screen to reveal the decoded answer through the decoding display window.
Abstract:
A calendar display includes a flat support defining a plurality of scored lines of structural weakness. A plurality of stacked sheets bearing weekly and monthly time indicia are removably connected to a front surface of the support adjacent to a first, upper edge of the support. An adhesive strip is located adjacent to the first, upper edge on a back surface of the support. Manipulation of the support by bending the support in predetermined directions about the scored lines of structural weakness and contacting the adhesive strip with the back surface of the support adjacent to a second, lower edge of the support permits the support to be configured as a self-supporting stand for displaying the sheets on a horizontal surface. The support also can be severed along a predetermined one of the scored lines of structural weakness to provide a display of the sheets which can be attached to a vertical surface by means of the adhesive strip or by a magnet connected to the back surface of the support adjacent to the first, upper edge of the support.
Abstract:
A book package of sheets including printed materials thereon comprised of printed writing of a connectible series of written expressions and a series of drawing illustrations compatible with the written expressions to allow the sheets to be chronologically and compatibly arranged in illustrated chronological form, a portion of the printed materials being printed in latent form which can be made visible with a marker included in the book package.
Abstract:
An educational device with which a user employs selected positioning of two masks over an array of normally unintelligible information to decipher an intelligible message therefrom, the positioning of the masks being determined by correctly associating useful information on a base member carrying the unintelligible information with markers and indicia carried on the masks and base member.
Abstract:
Teaching apparatus enabling a reviewer to review items of information to be learned by the reviewer in accordance with a prescribed routine of repetitive review of a plurality of information-bearing slips so that the review of unlearned items is more frequent than the review of learned items, the apparatus including a plurality of classification cards defining grades and classes within the grades, a tablet in the form of a board having delineated areas for separating the slips into groups which will be reviewed more frequently or less frequently, depending upon whether or not the item carried by a slip is known at the time of a particular review, and a holder for the slips, the holder being capable of holding a group of slips in a stack of variable height and enabling sequential review and removal of each slip from the stack of slips for placement on the tablet.
