Collaboration scripts can help learners to engage in argumentation and knowledge acquisition. However, they might have differential effects for learners holding differently structured knowledge (internal scripts) on argumentation. We investigated how external scripts interact with learners' internal scripts concerning collaborative argumentation. 98(More)
This chapter describes different script types that are involved when a person X is accomplishing a particular task Y. We refer to concepts and ideas from distributed cognition theories. It is assumed that individuals are holding internal scripts that guide them in the way they process tasks they are faced with, and these internal scripts are standing in a(More)
This article presents an outline of a script theory of guidance for computer-supported collab-orative learning (CSCL). With its 4 types of components of internal and external scripts (play, scene, role, and scriptlet) and 7 principles, this theory addresses the question of how CSCL practices are shaped by dynamically reconfigured internal collaboration(More)
We present a single solution for the following two problems: (1) to provide just-in-time support for collaborative learning tasks on top of arbitrary web pages (e. g. in order to foster online search competence) and (2) to transfer collaboration scripts implemented on a particular platform to other platforms. S-COL solves both by using fixed browser-side(More)
We use the script concept to describe knowledge structures that help individuals understand and act in specific contexts as well as scaffolds structuring collaborative learning. External scripts can be presented in different ways, e.g. as written text. For internal scripts, it is not clear whether they have identical effects on collaborative argumentation(More)
