<P>PROBLEM TO BE SOLVED: To provide a system that allows a user to learn a foreign language in a more natural way in everyday life. <P>SOLUTION: The system uses teaching materials in which character strings (words, etc.) existing in contents in a well-known language (mother tongue) are replaced by character strings (words, etc.) in an unfamiliar language (foreign language) to be learned. That is, part of the words or the like in the contents in the mother tongue is replaced by the foreign language to enable the user to learn words or the like in the contexts of the foreign language as if to learn words of a new mother tongue. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
