Expand to. The CPU 101 extracts words included in the teaching material content developed in the RAM 103 (405). For example, if the selected teaching material content is an arithmetic teaching material, words such as “circumference”, “area”, and “circumference ratio” are extracted. At this time, the entire range of the teaching material content regarding word extraction is not necessarily targeted, but the range displayed on the digital textbook terminal (parent) 402 may be targeted. The digital textbook terminal (parent) 402 registers in the flash memory 104 a word list 301 in which a unique number (hereinafter referred to as a word ID) is assigned to each extracted word. Further, the word list 301 is transmitted to the digital textbook terminal (child) 404 using the network control unit as search availability information. Thereafter, the teaching material content selected by the teacher 401 is displayed on the touch panel LCD 108 of the digital textbook terminal (parent) (406). On the other hand, when the student 403 selects the teaching material content on the touch panel LCD 108 of the digital textbook terminal (child) 404 in the same manner as the teacher 401, the teaching material content is displayed on the touch panel LCD 108 (408), so the student 403 browses the teaching material content.
