웹기반 프로젝트 학습에서 학습자 간 상호작용과 학습실재감이 학습성과에 미치는 영향 = The Effect of Interaction and Learning Presence on Learning Outcome in Web-Based Project Learning

국문 초록 (Abstract)

본 연구는 웹기반 프로젝트학습에서 학습자간 상호작용과 학습실재감이 성취도와 만족도를 예측하는지 알아보기 위해서 15주 동안 프로젝트학습을 진행한 63명의 대학생을 대상으로 연구를 진행하였다. 연구 결과 첫째, 학습자 간 상호작용은 β=.76로 성취도를 유의미하게 예측하는 변인으로 조사되었으나(t=9.15, p<.05), 만족도에 대한 예측은 유의미하지 않았다. 더 나아가 학습자 간 상호작용의 하위변인인 과제관련과 과제비관련 변인에 대해서 분석한 결과 학습자 간 상호작용은 그 유형과 관계없이 모두 성취도를 유의미하게 예측하는 것으로 조사 되었다. 둘째, 학습실재감은 β=.63로 만족도를 유의미하게 예측하였으나(t=6.35, p<.05), 성취도에 대한 예측은 유의미하지 않았다. 또한 인지적, 감성적, 사회적 실재감으로 분류된 학습실재감 하위요인 중 인지적실재감만이 β=.70으로 만족도를 유의하게 예측하는 것으로 분석되었다(t=7.74, p<.05).

다국어 초록 (Multilingual Abstract)

To investigate the influence of learner interaction and perceived presence level on the outcomes of learning, this study sampled 63 undergraduate students enrolled in a Web-based project course which lasted for 15 weeks. The numbers of task-related and task-not-related interaction in student messages were counted by sentence-unit. Perceived learning presence composed of cognitive, social, and emotional level was assessed by self-report items. Learning outcomes were gathered in terms of achievement and satisfaction. Followings are the results: (1) Total interaction significantly predicted achievement, β=.76 (t=9.15, p<.05), but not satisfaction. (2) Task-related interaction significantly predicted achievement, β=.40 (t=3.69, p<.05), and so did task-not-related interaction, β=.45 (t=4.23, p<.05). (3) Learning presence significantly predicted satisfaction, β=.63 (t=6.35, p<.05), but not achievement. (4) Among the sub-factors of learning presence, only cognitive presence significantly predicted satisfaction, β=.70 (t=7.74, p<.05), but not social and emotional presence. These results indicated that interaction and learning presence could be critical factors to improve learning outcomes in Web-based project learning. Details on the predictive power of each sub-factors could be used as the basis of future instructional design.
