초록

수업은 교수자와 학습자의 상호작용으로 정의될 수 있으며 학습자의 능동적 활동에 의해 학습 성과가 향상될 수 있다. 그러나 교수자에 의해 작성되고 배포되는 강의자료, 교수자의 일방적인 강의, 페이퍼위주의 과제 제출 등으로 학습자의 적극적인 학습참여가 제한되고 있다. 본 논문에서는 학습자가 스스로 발견한 지식을 개념화하고 지식 구조를 정의함으로써 학습자 온톨로지를 생성하는 방법을 제안한다. 또한 교수자 온톨로지와의 연계를 위해 온톨로지 매칭 및 연계 기법을 제안한다. 교수자 온톨로지와 학습자 온톨로지는 통합되어 학습 온톨로지를 구성하며 이 온톨로지를 토대로 교수자와 학습자들 사이에 토론, 발표, 지식 공유 등이 이루어진다. 제안하는 온톨로지 기반 학습은 실제 수업에 적용되었으며 학습자들의 피드백 분석을 통해 그 효과를 보였다.

Teaching is communication between instructor and students. The learning outcomes can be enhanced by active learning of students. However, there are many obstacles to effective learning below, such as lecture notes authored by instructor, passive student participation, and paper-based homework. In this paper, we propose an effective method for enhancing learning effect through constructing learner ontologies in which knowledge discovered by students is conceptualized and organized. The learning ontology is composed of a teacher ontology and many learner ontologies. The learning ontology is used in discussion, visual presentation, and knowledge sharing between instructor and students. We used the learning ontology in two lectures in practice and learned that the learning ontology enhances learning effect through analysis of feedbacks of students.
