Conceptual modeling (CM) is an important technique in database design. Education of the technique is a challenge of computer science departments in higher education institutions.The aim of this study is to find patterns of learners' errors in their artifacts and their artifact making processes in conceptual modeling exercises.This study collected the data of learners' artifacts and the process of creating them in an exercise of CM using a system, KIfU 3.0, and conducted an association analysis with this data.As a result, this study found the association rules regarding learners' errors in the artifacts and/or their characteristics of the artifact making processes.For example, there are some errors that have a tendency to co-occur in the learners' artifacts, and learners who refine their artifacts frequently tend to detect attributes of concepts successfully even though they are hard to detect from a requirement specification for the exercise.This fact implies the effectiveness of our approach and a suggestion to improve teaching of the CM.
