“…Martinez et al [13] presented a tool for processing event logs of the BSCW using a social network analysis method. Other approaches, focus on processing event log files for analyzing the dialogue and interaction (Avouris et al [14]), or for using them in query systems to increase awareness (Hardings [15]). On the one hand, these approaches consider the processing of the data just for a specific purpose, limiting thus the scope of the developed tools.…”

Providing collaborative learning applications the possibility to offer continuous awareness to on-line collaborative learning teams is a challenging issue since it is essential to keep participants informed of both what is happening and what happened in the learning group. Moreover, awareness is the basis to enhance collaboration and improve the individual and group performance since it allows to track and assess the collaborative learning process more objectively and to model students' behavior more efficiently. In order to provide students and tutors with effective awareness, we consider the collaborative actions registered in log files. It is necessary to process large and considerably complex event log files in a constant manner, and thus it may requires processing capacity beyond that of a single computer. To that end, in this paper we show how a Grid approach can considerably decrease the time of processing group activity log files and thus allow students and tutors to be aware of what is going on in the group activity even in real time. Our approach is based on the master-worker paradigm and is implemented using Globus technology running on the Planetlab platform. To test our application, we used event log files from the Basic Support for Collaborative Work (BSCW) system.

“…Simple solutions, described in section 2, are available for linking a textual contribution to a specific element of a graphical representation and for referencing a graphical element in a textual production. The most recent synchronous CSCL environments provide several tools in each space (Avouris et al, 2004), (Pinkwart, 2003), (Lonchamp, 2006). Therefore, the linking problem encompasses both intra and inter-space linking.…”

In CSCL systems, linking conversations and task objects is essential for establishing joint attention and constructing shared meaning. This paper proposes an application-independent linking mechanism, well adapted for expressing complex inter-tool links as required by the most recent synchronous CSCL environments. The sticky annotated snapshot concept and its more classical derivatives, sticky note and persistent graphical pointer, are described together with their implementation. Preliminary use experiences are discussed which show, in addition to normal linking usages, a somewhat unanticipated way of using sticky annotated snapshots as fully-fledged intermediary objects during creative processes.
