Abstract

This study proposed the ubiquitous learning system by finding the difficulties which students have in learning the course of science and analyzing the current learning applications that are used commercially. Through case studies, we found 4 problems. First, the request of long learning time by most of the existing video-based learning applications. Second, it is impossible to know their level of learning due to the lack of open learning contents. Third, it is difficult for learners to participate in interactive learning. Fourth, there are educational contents without considerations on the level of learners. To refine the difficulties due to these problems, we designed and implemented a new ubiquitous learning system which applies the small learning contents for short-term learning, open learning system and enhanced hierarchical learning contents. The system was implemented based on Android. It provides learners with useful science education. We conducted a questionnaire for third grade middle school students in order to show that the proposed system has a good educational effects. The questionnaire asks for the differences between the proposed ubiquitous learning system and the existing learning application. We concluded that the proposed system is better than the existing application by using t-test for improvement of learning effects using feedback with which students participate in interactive learning but not in unidirectional learning, and share the learning result.

본 연구는 과학 교과목 학습에 대한 학생들이 가지는 학습적 어려움을 파악하고 기존 연구와 시중에 사용되는 학습 애플리케이션들을 분석하여 U-러닝 시스템을 제안하였다. 사례조사를 통해 기존 대다수 학습 애플리케이션이 가지는 동영상 기반으로 인한 긴 학습시간의 요구와 개방형 학습콘텐츠의 부족으로 인해 학습자들이 자신의 학습 수준을 파악할 수 없다는 점과 양방향 참여가 어렵다는 문제점, 그리고 학습자 수준을 고려하지 않은 교육 콘텐츠 제공과 같은 문제점들을 발견하였다. 이를 보완하기 위해 단기학습 단위의 소규모 학습 콘텐츠, 개방형 학습 시스템, 강화된 계층적인 학습 콘텐츠 등의 설계요소들을 적용하여 새로운 U-러닝 시스템을 설계하였다. 설계된 시스템을 안드로이드 기반으로 구현하여 학습 대상에게 유익한 과학 교육을 제공하였다. 제안한 U-러닝 시스템이 교육 효과가 있음을 보이기 위해 중학생 3학년을 대상으로 설문조사를 실시하였다. 설문조사에서 기존 학습 애플리케이션과 본 논문에서 제안된 U-러닝 시스템을 모두 이용하게 하였다. 분석 결과로서 일방적인 단방향 학습이 아닌 양방향으로 학습에 참여하고, 학습결과를 공유하여 피드백이 가능함으로써 학습효과가 얻어 질 수 있음을 t-검정으로 확인하였다.
