다차원 학습경로 패턴 분석 시스템의 설계 및 구현

Abstract

In learner-controlled environment where learners can decide and restructure the contents, methods and order of learning by themselves, it is possible to apply individualized learning in consideration of each learner’s characteristics.The present study analyzed learners’ learning path pattern, which is one of learners’ characteristics important in Web-based teaching-learning process, using the Apriori algorithm and grouped learners according to their learning path pattern. Based on the result, we designed and implemented a multi-dimensional learning path pattern analysis system to provide individual learners with learning paths, learning contents, learning media, supplementary learning contents, the pattern of material presentation, etc. multi-dimensionally. According to the result of surveying satisfaction with the developed system, satisfaction with supplementary learning contents was highest (Highly satisfied”24.5%, Satisfied”35.7%). By learners’ level, satisfaction was higher in low-level learners (Highly satisfied”20.2%, Satisfied”31.2%) than in high-level learners (Highly satisfied”18.4%, “Satisfied”28.54%). The developed system is expected to provide learners with multi-dimensionally meaningful information from various angles using OLAP technologies such as drill-up and drill-down.
