Abstract
In an education system using a network, a method for automatically detecting a defective part in an education material and for indicating the defective part is provided. A defective information storing means for storing a defect point correlation with a portion of an education material is provided. When the system receives a question from a student's terminal PC, a defect point of a corresponding portion of an educational material, in the defective information storing means, is updated, based on the received question. By this update, whenever a question is sent from a student's terminal, a defect point stored correlation to a portion of an educational material is accumulated. It is judged whether the defect point reaches a predetermined threshold value, and the corresponding portion of the educational material is transmitted to a terminal of a system administrator, based on the result of the judgement. Accordingly, a defective part of each educational-material unit and the nature of the defectiveness can be easily detected by the system administrator.
