PROBLEM TO BE SOLVED: To provide an operation terminal device for displaying and operating contents. SOLUTION: A computer device 21 reads constitution data out of a teaching material platemaking content database 52 stored with class data for classes, a training moving picture database 53, a training still picture database 54, and a problem collection text content database 55 and displays the read constitution data on the screen of the terminal device 22 for operation. When a user selects a specific part of the constitution data displayed on the screen, the computer device 21 generates a sub-window on the screen of the terminal device 22 for operation, displays constitution data linked to the specified part in the sub-window, and outputs the constitution data to a large-sized display device 23 and an audio output device 24 through an output part. When the user releases the selection of the specific part, the output to the large-sized display device 23 and audio output device 24 is stopped. COPYRIGHT: (C)2005,JPO&NCIPI
