Autocorrecting device comprising a support; at least two constant-diameter objects that can be rotated, at least one of the objects being referred to as determinant, the other at least one object being referred to as determined, each of the objects being provided with at least one stimulus associated with an angular position of the object; a drive means for driving the objects in rotation and having an object-driving torque M; a rotational blocking means for angularly blocking a determinant object in position; a selection means for selecting an angular position of a first object with respect to a second object, the selection means applying a resistive torque Cr between the first and second objects the two objects having a coupled position in which the resistive torque is higher than the driving torque M and an uncoupled position in which the resistive torque is lower than the driving torque M.

A rotatable language demonstration device is an apparatus that is used to teach languages easily and efficiently in a dynamic and engaging manner to accommodate different learning styles of the students. The apparatus may include at least one demonstration mechanism, a plurality of display tiles, and an elongated frame. The at least one demonstration mechanism provides multiple surfaces for the user to write on without having to erase and rewrite the already written content. The plurality of display tiles enables the quick editing of the written content on the at least one demonstration mechanism. The elongated frame supports the at least one demonstration mechanism in an upright orientation so that the writable surfaces of the at least one demonstration mechanism are easily reachable by the user. The at least one demonstration mechanism includes a plurality of turnable wheels that enables the easy rearrangement of the writable surfaces.

A language learning assembly includes a body having at least one first recess and at least one second recess arranged parallel to the at least one first recess. A plurality of blocks are color-coded by syntax category or “parts of speech” and have a plurality of words displayed on each block. The blocks are sized to fit side-by-side within one of the at least one first recess and the at least one second recess to form grammatically correct sentences. Each block can have a different word on at least two faces thereof. Some of the blocks can be configured to display words in a fixed fashion. Some of the blocks can have electronic displays configured to display words electronically.

A multi-layer toy having at least one outer layer adjacent a planar layer or a ball where both the outer layer and the adjacent planar layer or ball each contain related information such that, in play, the information on the outer layer is made to align with the related information on the adjacent planar layer or ball. The information can comprise depictions of objects, things, characters, animals, or words, for a matching game, or the information can comprise numbers for a counting or mental math game. The toy is preferably sized to be hand-held.

The invention relates to a device for the representation of tactile characters, in particular in Braille, comprising tactile elements which are combined in groups, wherein a tactile character consists in each case of a matrix of tactile points, which can be arranged in two adjacently arranged columns of points and at least two lines of points, wherein the four possible combinations of two tactile points of tactile points arranged adjacently in a line of points are in each case arranged on a common tactile element.

A device for testing cognitive development of a user; the device includes a housing and a test-member. Further, in a preferred embodiment, the device includes a cover-portion and a plurality of test-blocks. The device is useful for testing the cognitive development of the user by providing a revolving-test member including a plurality of test-displays each having a different development topic for testing.

A method for adaptively teaching content to a user comprises providing a plurality of teaching topics. The method includes sequentially associating a lead problem and a plurality of secondary problems with each of the plurality of teaching topics. Each of the lead problems and the plurality of secondary problems is an open-ended puzzle having a range of solutions and a difficulty rank. The range of solutions for each of the lead problems and the plurality of secondary problems has an optimal solution and a plurality of secondary solutions. A teaching topic is selected and a corresponding lead problem is presented to a user. User provides answer data via a physical input device having enmeshed gears. The user is provided another secondary problem in the selected teaching topic if the answer data matches one of the secondary solutions. The user is provided another lead problem if the answer data matches the optimal solution.
