Studies in computer supported collaborative learning frequently under-expose the interaction between students and technology. To gain more insight in the way student groups interact with educational technology, we examine how students `appropriate' this technology. The notion of technology appropriation implies a process of social construction in which the actions and thoughts of the user are shaped by the technology, while the meaning and effects of the technology are shaped through the users' actions. In this paper, we develop a problem analysis from theoretical findings, and work towards an initial, tentative concept of technology appropriation. Key words: Collaborative learning, Technology appropriation, Discussion support, Face-to-face discussions.
