CSCL에서 공유 리더십과 질문활용 스캐폴딩이 협력적 문제해결에 미치는 영향 = The Effect of Shared-leadership and Questioning Scaffolding on Collaborative problem solving in CSCL

다국어 초록 (Multilingual Abstract)

The purpose of this study is to explore the instructional effects of shared-leadership and questioning scaffolding on collaborative problem solving in CSCL. Participants do a collaborative problem solving activity in developed CSCL environment. Dependant variables in this research are problem solving process and outcome. Problem solving processes are measured by message frequency, problem solving score and problem solving outcomes are measured by portfolio, shared mental model. Participants are 84 college students and experiment period is 6 weeks.
In conclusion, firstly, Questioning scaffolding in CSCL is effective for supporting team members' active interaction. But no significant differences in some dependant variables indicate that every team members couldn't use questioning scaffolding, so instructor should give modeling or monitoring support. Secondly, Shared-leadership in CSCL is not effective for collaborative problem solving consistently. This result indicate that shared-leadership by leader change could facilitate team members' interaction in some respect, but also hinder deep discourse among team members in other respect. So we need other supporting system for team members' role and activity.

본 연구의 목적은 CSCL에서 공유 리더십과 질문활용 스캐폴딩이 협력적 문제해결에 어떤 영향을 주는가를 알아보는 것이었다. 연구목적을 위해 개발된 CSCL환경에서 학습자들은 일련의 협력적 문제해결활동을 수행하였으며, 처치 효과를 분석하기 위하여 문제해결과정에서 나타난 단계별 메시지 빈도수 및 문제해결점수, 최종결과물인 포트폴리오, 공유정신모형을 분석하였다. 본 실험은 84명의 대학생을 대상으로 이루어졌으며, 연구기간은 6주 동안 진행되었다.
연구 결과, 질문활용 스캐폴딩 제공은 팀 구성원들의 적극적인 상호작용을 지원하는데 효과적인 것으로 나타났다. 그러나 일부 요인들에서 유의미한 차이가 나타나지 않은 것은 모든 구성원이 이를 잘 활용하지 못할 수 있었음을 보여주며 따라서 이를 위한 교수자의 모델링 및 모니터링 지원이 필요함을 시사한다. 공유 리더십의 경우, 문제해결 과정 및 결과에서 일관된 결과를 보이지 않았다. 이는 조장 변동을 통한 공유 리더십이 팀 구성원간 활발한 상호작용을 유발하기도 하지만, 심층적 논의에는 오히려 방해가 될 수 있음을 시사한다. 따라서 각 구성원들이 역할과 활동상황을 인식하기 위한 지원체제가 필요함을 알 수 있다.
