Abstract

The purpose of this study was to quantitatively evaluate the effectiveness of learning management systems (LMS) in the physical geography class. The study adopted the experimental design and three classes participated in this study. The first class was controlled using only classroom lectures, the second class used PPT slides along with the classroom lectures, and the third class used online video clips along with the lectures. The experiments were conducted from the Spring Semester 2007 to the Spring Semester 2008 for the introductory physical geography course. The study results showed that online learning tools help students improve academic performance and their attitudes towards the class and the instructor. Compared to simple PowerPoint slides, voice recording attached to the visual lecture slide materials enhanced students' motivation. Class lectures with lecture slides did not improve students' scores. However, when the visual materials were combined with voice recording, the number of internet access to online class materials increased, and class attendance and students' final grades were improved. Based on the results, the instructional design model that combines classroom and online learning was suggested.

현재 대부분의 국내외 대학과 교육 기관에서는 온라인 학습방법을 채택하고 있다. 이에 본 연구는 전통적인 교수법에 대한 상대적 이점으로 많은 온라인 학습도구를 통한 학습효과를 자연지리학 강좌를 중심으로 정량적으로 평가하고자 하였다. 자연지리학 수강자들을 대상으로 실험을 실시하였으며, 인터넷 상에서 정보의 전파 도구로 널리 사용되고 있는 RSS(Really Simple Syndication) 기반의 Podcasting과 Profcast 소프트웨어 프로그램을 이용하여 생성한 동영상 강의가 온라인 도구로 활용되었고, 전통적인 강의실 수업도 함께 병행하였다. 학습효과를 살펴보기 위해, 수강자들이 작성한 강의평가 자료를 분석하였다. 실험은 2007년 봄학기부터 2008년 봄학기까지 동일한 자연지리학 개론 강좌를 대상으로 실시되었다. 본 연구에서 다루어진 실험의 결과에 의하면 온라인 학습 도구는 학습자들의 학습 효과뿐 아니라 수업과 강사에 대한 태도를 긍정적으로 변화시키는 것으로 나타났다. 또한 단순한 PowerPoint 슬라이드만 제공될 때에 비해 교수자의 음성 녹음이 결합된 강의자료가 학습 동기를 높이는데 더욱 효과적인 것으로 조사되었다. 즉, PowerPoint 슬라이드와 같은 시각적인 강의 자료만 제공되는 경우에는 기존의 강의방식과 학습 효과 면에서 큰 차이를 보이지 않았으나, 시각자료에 강의음성이 결합되었을 때, 인터넷 학습자료에 접근하는 빈도가 증가하고 학업성적 및 수업 출석률이 향상되었다. 연구 결과를 바탕으로 온라인과 교실 학습을 병행한 블랜디드형 교수설계 모델이 제안되었다.
