APPARATUS FOR DIAGNOSING LEANER USING RELIABILITY OF COGNITIVE DIAGNOSIS MODEL AND METHOD THEREOF

摘要

The present invention relates to an apparatus for diagnosing a learner using the reliability of a cognitive diagnosis model and a method thereof. The method for estimating the reliability of a cognitive diagnosis model to estimate concept vector () of a learner through Q matrix (metrics for problems) and R matrix (metrics for responses to problems) comprises the steps of: assuming a probability P(X) of a learner response (X) when the concept vector () is given; obtaining a probability P(X) for each concept pattern of the learner from the concept vector () of the assumed learner and the learner response (x); obtaining an information entropy (H) value of the learner from the probability P(X) of the concept pattern of the learner; and obtaining a reliability () of an estimation result of understanding of concept for each learner using the information entropy value (H) of the learner and the number of concepts.;COPYRIGHT KIPO 2020
