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.

Claims

1. A method for indicating a defective part in an educational material in a system for providing an educational service using a network,

wherein said system comprises,

a receiving step for receiving a question from a student'"'"'s terminal,

a updating step for updating a defect point of a corresponding portion of an education material, in a defective information storing means which stores the defect points correlation with the portions of the educational materials, based on the question received in said receiving step,

a judging step for judging whether said defect point has reached a predetermined threshold value by the update in said updating step, and

a transmitting step for transmitting said portion of the educational material to a terminal of a system manager, based on the result of the judgement in said judging step.

2. A method for indicating a defective part in an educational material according to claim 1, wherein said updating step updates a defectiveness point of a corresponding portion of an education material, in a defective information storing means which stores the defect points correlated with the portions of the educational materials, based on the question received in said receiving step, with reference to a weight storing means which stores a weight assigned to a keyword appearing in each portion of the educational material.

3. A method for indicating a defective part in an educational material according to claim 2, wherein a weight is set for a new keyword, a supplemental keyword and a reference keyword, in this order, from the largest weight, in said weight storing means.

4. A program product for indicating a defective part in an educational material, wherein it operates steps, using a computer, comprising:

a receiving step for receiving a question from a student'"'"'s terminal,

a updating step for updating a defect point of a corresponding portion of an education material, in a defective information storing means which stores the defect points correlated with the portions of the educational materials, based on the question received in said receiving step,

a judging step for judging whether said defect point has reached a predetermined threshold value by the update in said updating step, and

a transmitting step for transmitting said portion of the educational material to a terminal of a system manager, based on the result of the judgement in said judging step.

5. A computer-readable recording medium which records therein a program for indicating a defective part in an educational material, by which a computer operates steps comprising:

a receiving step for receiving a question from a student'"'"'s terminal,

a updating step for updating a defect point of a corresponding portion of an education material, in a defective information storing means which stores the defect points correlated with the portions of the educational materials, based on the question received in said receiving step,

a judging step for judging whether said defect point reaches a predetermined threshold value by the update in said updating step, and

a transmitting step for transmitting said portion of the educational material to a terminal of a system manager, based on the result of the judgement in said judging step.

6. An apparatus for notifying a defective part in an educational material comprising:

a receiving means for receiving a question from a student'"'"'s terminal,

a updating means for updating a defect point of a corresponding portion of an education material, in a defective information storing means which stores the defect points correlated with the portions of the educational materials, based on the question received in said receiving means,

a judging means for judging whether said defect point reaches a predetermined threshold value by the update in said updating means, and

a transmitting means for transmitting said portion of the educational material to a terminal of a system manager, based on the result of the judgement in said judging means.
