>>이 연구는 웹기반 상황학습에서 과제상호의존성과 보상상호의존성 유형에 따른 과제수행이 집단의 과제수행과정과 과제수행결과에 미치는 영향을 실증적으로 분석하였다. 연구결과, 과제상호의존성의 경우 팀중심 과제상호의존성 집단이 과제수행과정과 과제수행결과의 전 영역에서 호혜적 상호의존성 집단에 비해 유의미하게 높은 점수를 얻은 것으로 나타났다. 보상상호의존성 유형의 경우, 집단적 보상이 정서적 반응인 구성원에 대한 감정적 수용을 비롯한 전 영역에서 독립적 보상에 비해 유의미하게 높은 점수를 얻은 것으로 나타났다. 그러나 과제상호의존성과 보상상호의존성의 상호작용 효과는 관찰되지 않았다. 이러한 결과는 웹기반 상황학습에서 학습자의 과제수행을 효과적으로 지원하기 위해서는 과제상호의존성을 팀중심으로 설계하고, 집단적 보상을 제공함으로써 자료, 정보, 전문성, 상호간의 아이디어 교류를 활성화할 수 있음을 시사해준다.


The purpose of this study was to investigate the effects of task interdependence types and reward interdependence types on task performance outcomes and processes in web-based situated learning environment using Shadow NetworkSpace. The Theoretical framework for this study is based on web-based situated learning, community of practice, task interdependence, reward interdependence. In this study, the task interdependence types, consisting of sequential, reciprocal, and team-based and reward interdependence, consisting of independent and collective were designed. In addition, task performance outcomes are composed of problem solving performance and task performing competency and task performance processes are composed of the perception on the individual efforts, group efforts, and group efficacy. Subjects of this study were 220 fifth grade elementary school students. By forming a team comprised of 4~6 pupils, according to task interdependence and reward interdependence types in six groups, seven teams were randomly assigned to each group. As for study procedure, after verifying homogeneity of the six groups, prior practice activities were conducted for a week. After they acquired the program function, they conducted three tasks included in the environmental education unit in the subject of science. The results showed that, task interdependence had effects on problem solving performance, task performing competency, individual efforts and group efforts whereas reward interdependence had effects on task performing competency, individual efforts and group efforts. Finally, both of two independent variables had effects on the group efficacy.
