In a computer-assisted learning apparatus for mastering learning contents through simulated experience, a display screen is divided into multiple small screen sections. An explanation text display field, in which explanation text related to predetermined training contents is to be displayed, is assigned to one of the small screen sections, and related-information display fields, in which detailed information and/or illustrated information associated with the contents described in the explanation text display field is to be displayed, are assigned to the remaining small screen sections. A trainee learns based on the explanation text and its related information.
