Disclosed is a system and method for recommending books based on a vocabulary of a user and coordinating books and user vocabulary growth trajectory in such a way that makes it possible for the user to read books of their choice before reaching the vocabulary size sufficient to read, with adequate comprehension, practically any book in general while maintaining a sustainable speed of vocabulary growth. Further disclosed is a vocabulary-based flashcard generator assistant system that allows users to quickly create high-quality flashcards with personalized and optimal content.

The present invention relates to a dynamic three-dimensional teaching aid that allows for alphabet teaching or storytelling for infants or children in diversified manners by dynamic movement of a teaching member with teaching content when the teaching member is moved, thereby stimulating indefinite curiosity and imagination of infants and children, meeting their learning ability, arousing interest not to be bored and to appear novel despite repeated use, and letting them actively participate in and focus on learning and that has a simplified structure, is easy to manipulate, and is accurately controllable for its movement. More specifically, the dynamic three-dimensional teaching aid is configured so that a first magnet 23 is moved under a teaching board 1 by a control rod 2, and a moving block 3 coupled with a teaching member 4 is placed, which includes an attractive force element to be attracted by the first magnet 23 and a second magnet 32, on a side of the attractive force element, to exert a repulsive force to the first magnet 23 to be rotated depending on changes in the moving direction.

A personal electronic device is adapted to construct data tables from user input received over time relating to translations of translatable items from a first language to a second language. Entries in a data table for a user are dynamic and may indicate likelihoods of the user correctly translating translatable items as a function of time. Each translatable item may have a different time-dependent likelihood of a correct translation. Operation of the personal electronic device for a user may be based in part on the acquired, time-dependent likelihoods for that user, so that information may be presented to the user in a more efficient manner.

A fabric includes an inner layer, a metallized membrane disposed on the inner layer, and an outer layer disposed on the metallized membrane. The metallized membrane includes a base layer containing a polymer and a metal layer deposited on a first surface of the base layer. The inner layer is coupled to the metallized membrane via first point contacts, and the outer layer is coupled to the metallized membrane via second point contacts.

The present disclosure provides methods, tools, kits and electronic systems for transcribing non-Chinese language sounds into sound-associated Chinese language characters. The methods, tools, kits and systems use language devices (dictionaries and blocks) based on sound-associated Chinese characters obtained by parsing standard Chinese characters sounds into consonant sounds and vowel sounds which have correspondence to certain standard phonetic graphemes. Sequences of the sound-associated Chinese characters provide existing Chinese phonemes which represent specific sound sequences and syllables in the non-Chinese language.

The invention relates to methods for memorizing words in a foreign language. A method provides for the rendition of a foreign song and the synchronous presentation of textual subtitles on a display. The subtitles are produced on the display in the form blocks (1) arranged one below the other, each of which contains a fragment of the lyrics to the song and consists of three separate lines: the line (2) of the text of the song in a foreign language, the line (3) of the text of the translation into the native language and the line (4) of the pronunciation of the words to the foreign song in the characters of the native language alphabet, which corresponds to the middle line of the block (1). The block (1) is divided into columns (5), in each of which one word or phrase of the line (2) of text of the song in the foreign language.
