CSCL 환경에서 협력학습 지원 도구의 유형이 협력적 지식 구축에 미치는 영향

초록

Most of learners don't build a collaborative knowledge effectively in CSCL environment. They have some difficulties in collaborative knowledge construction activities for coordination and communication. Thus, we may need to provide learners with scaffolds that could support coordination or communication activities by coordination supporting script and communication supporting script. These scripts are complementary (Dillenbourg & Betrancourt, 2006), and could have synergetic effects on collaborative knowledge construction in CSCL environment(Reiser, 2002). In particular, it needs to complement the weak points of the communication supporting script by means of script affordance. The purpose of this study was to examine the effects of three types of collaboration supporting tools(coordination & communication supporting script with script affordance, coordination and communication supporting script, and coordination supporting script) on process and outcomes of collaborative knowledge construction in CSCL environment. The results of this study showed that the coordination & communication supporting script with script affordance generated significantly more learners' participations and higher scores of domain-specific knowledge than coordination supporting script. Some learners under the condition of coordination & communication supporting script with script affordance produced higher quality of learning outcomes than learners under the condition of coordination supporting script. These could be a partial evidence of what coordination & communication supporting script with script affordance could support a collaboration knowledge construction effectively.
