다국어 초록 (Multilingual Abstract)

The purpose of this study is to investigate how learners act in online Problem Based Learning(PBL) environment. A case study was performed to investigate messages of learners. The case for this study was a graduated course which was implemented in online PBL. To identify characteristics of learners` activities, a content analysis was conducted with the messages that learners posted on the web bulletin board utilized for the case course. The framework of the message analysis was based on Barrows` two books: What Your Tutor May Never Tell You and The Tutorial Process. The framework consists of three main groups and eighteen subgroups of categories; 1) Building up relationships: self-introduction, gossip, and support, 2) Managing a team: news, ideas, support, question and answer, and assignment, 3) Solving problems: ideas, facts, agreement, support, materials(data), critical ideas, summary, and decision. The results of the study demonstrate as follows; 1) Learners performed their tasks for building up relationships and managing their team. 2) But, learners did not fully experience PBL process of which Barrows had emphasized the importance. Based on the results, it is suggested that we consider Blended PBL, which combines online and offline PBL in order to make up for the identified deficits of current online PBL in regards to learner experience. Also, the role of tutor as process guide with minute attention needs to be emphasized.
