METHOD OF RENEWING DEGREE OF DIFFICULTY BY STUDY-GROUP IN E-LEARNING SYSTEM OF PROVIDING QUESTION BY DEGREE OF DIFFICULTY AND E-LEARNING SYSTEM OF PROVIDING QUESTION BY DEGREE OF DIFFICULTY WITH RENEWING DEGREE OF DIFFICULTY BY STUDY-GROUP IN REAL-TIME

摘要

A degree of difficulty item offer learning system having the studying group item degree of difficulty renewal method by group degree of difficulty update function improving the reliability about the degree of difficulty of the item for the setting questions in the learning system providing the degree of difficulty item are provided to calculate and update a learning level and produce the degree of difficulty of the item for the setting questions about the studying groups of the different plurality. A difficult degree classified item provision learning system produces an accumulation correct answer rate of a learning group and an accumulation answerer number(S620). The degree of difficulty item offer learning system produces the statistic difficult degree of the ith studying group about the item for the setting questions based on the accumulation correct answer modulus of the calculated ith studying group(S630). The degree of difficulty item offer learning system produces the first of the ith studying group and the second weighted value based on the accumulation number of respondent of the calculated ith studying group(S640). The degree of difficulty item offer learning system renews the fixed number which approaches the value adding the person who contributes questions for an examination degree of difficulty in which the first weighted value is given(S650).
