LEARNING SUPPORT SYSTEM HAVING CONTINUOUS EVALUATION FUNCTION OF LEARNER AND TEACHING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a learning support system capable of realizing highly efficient learning support compatible to an actual state by evaluating the possibility of presence of a teaching material obsolete or including errors and the possibility of a difference in difficulty of storing and fixing due to question difficulties or characteristics or learner's characteristics.;SOLUTION: This learning support system is characterized in that question information 310 includes question sentences, solution information, and achievement target values, learning history information 400 includes question information identifier 311, a learner identifier 210, and achievement information 420, and an analysis unit 104 includes means 712 for continuously estimating and recording the academic level probability distribution 711 of a learner and the difficulty level probability distribution 721 of questions by a machine learning algorithm on the basis of the learning history information, and means 715 for calculating and recording an oblivion function indicating how much the learner has lost stored learned question information in a time axis after learning by utilizing the academic level probability distribution of the learner, the difficulty level probability distribution of questions, and the learning history information.;SELECTED DRAWING: Figure 7;COPYRIGHT: (C)2017,JPO&INPIT
