Using online learning environments in higher education offers innovative possibilities to support collaborative learning. However, online learning creates new kinds of problems for participants who have not previously worked with each other. One of these problems is uncertainty which occurs when participants do not know each other. According to the uncertainty reduction theory, low uncertainty level increases the amount of discourse and decreases the amount of information seeking. Therefore, uncertainty may influence online discourse and learning. This study investigates the effects of an epistemic cooperation script with respect to the amount of discourse, information seeking and learning outcomes in collaborative learning as compared to unscripted collaborative learning. The aim was also to explore how and what kind of information learners seek and receive and how learning partners react to such information exchange. The participants were 48 students who were randomly assigned to groups of three in two conditions, one with and one without an epistemic script. The results indicate that the epistemic script increased the amount of discourse and decreased the amount of information seeking activities. Without an epistemic script, however, learners achieved better learning outcomes. The results of two qualitative case-based analyses on information seeking will also be discussed.Keywords: collaborative learning, online learning environment, uncertainty reduction theory, cooperation script, amount of discourse, information seeking Epistemic cooperation scripts 4
Epistemic Cooperation Scripts in Online Learning Environments: Fostering Learning byReducing Uncertainty in Discourse?Online learning environments can, for example, enhance collaborative learning in higher education by providing shared workspaces in which learners can work together on authentic problem cases (e.g., Strijbos, Kirschner, & Martens, 2004). However, online learning environments do not guarantee that learners will interact with each other (Kreijns, Kirschner, & Jochems, 2003). People participating in online learning courses often do not know each other and are unsure how to act in these learning environments. In initial interaction situations there is some degree of uncertainty (Berger & Bradac, 1985;Berger & Calabrese, 1975), and online, often physically distanced learning environments lack immediate feedback and non-verbal cues, which might further increase uncertainty (e.g., Järvelä & Häkkinen, 2002;Roschelle & Pea, 1999).Uncertainty can appear at two different levels: at the socio-emotional level and at the epistemic level (Mäkitalo, Pöysä, & Häkkinen, 2003). At the socio-emotional level uncertainty can occur, for example, when participants do not get immediate feedback on how others are reacting to their messages, whether they agree or disagree with one's suggestions and how they will organize their joint work. At the epistemic level, participants may be uncertain about the content-wise quality of their contributions: Are their contri...
