Abstract
Abstract A learning device is provided with an information processing unit, a keyboard for inputting characters, an information storage medium for storing a variety of data, a CRT display for displaying characters and/or figures, and a mouse for designating a specific location on the CRT display. The information storage medium stores a plurality of learning materials of which respective learning items has a tree structure. The information storage medium also stores the tree structure of the learning items, the name of each learning item, the names of learning items positioned at next upper and next lower levels in the tree structure, and the name of a learning material corresponding to each learning item. A learner can instruct the CRT display to display a portion or all the tree structure using either the keyboard or the mouse. Also, the learner can alter the display range according to his intention. When one of the learning items displayed on the CRT display is designated by the mouse, the name of the corresponding learning material is initially read and a learning material having the read name is then called.
