웹기반 PBL환경에서 공유지식 형성에 영향을 미치는 팀 학습활동 특성 규명 = Identifying Characteristics of Team Learning Behavior for Shared Knowledge Building in the Web-based PBL

다국어 초록 (Multilingual Abstract)

The purpose of this study is to search the ideas for design and applying of effective and efficient web-based PBL environment based on the identifying of team learning behavior factors and examining the comprehensive process of shared knowledge building that have impacts on learning outcomes. For this purpose, a course from a virtual campus of the university located in Seoul was chosen to collect and analyze the relating data. The underlying design of this course was based upon the PBL theories and practices. Five to six students were randomly assigned to form fourteen teams working in the web-based PBL for 6 weeks. During the web-based PBL process, characteristics of shared knowledge building of each team was observed with the collections of synchronized and asynchronized interaction messages. In order to identify team differences in the team learning behavior, the two higher performance groups and two lower performance groups were selected, and their learning behaviors were comparatively analyzed based on the team`s performance outcomes. The major finding this study are as follow. first, there have been the qualitative and quantitative differences in diversity, density and representational method of the discussed messages according to learning performance level. second, frequency of the team learning behavior and interaction for making social relationships strongly correlated with similarity of the shared team knowledge structures. In addition, the accuracy of shared team knowledge structures correlated with the learning behaviors, for example, generating and discussing ideas to achieving meaningful solutions in the problem solving process.
