Poole, University of Missouri-Columbia Abstract This study investigated how participants (39 teenagers and 10 college–age online mentors) interacted and constructed shared knowledge of concepts, goals, tasks, procedures, and solutions when solving a real-world problem in an Internet-mediated project-based learning environment (iExpeditions). iExpeditions is a website that provides a coordinated set of communication and collaboration tools, including chat rooms, a discussion forum, "notes" (an intranet email tool), and "logs" (electronic journals). The main focus of this study was on how different patterns of participant interaction contributed to the social construction of shared knowledge. We took a case study approach, examining the knowledge construction process of two of the six online teams involved in the project. The communication artifacts within the two teams were analyzed through psycholinguistic discourse analysis (Edwards & Mercer, 1987). We discovered a three-stage pattern of knowledge construction that occurred in the iExpeditions environment: a) interacting with the expedition guiding materials and online resources, b) interacting with peers online, and c) sharing the knowledge constructed with an outside audience. The findings of this study have implications for the development and implementation of this and other computer supported collaborative learning (CSCL) environments. In particular, our findings point to the importance of the role of the mentor and the opportunity for participants to voice differing ideas as critical to the construction of shared knowledge....
