“…Experimental results from previous research [7], [11] allow us to be confident with the gain provided by our Grid approach in terms of relative processing time and the benefits of using the inherent scalable nature of Grid while user concurrency is high and the input log files are growing up in both number and large size. The ultimate aim of this study is to show the feasibility of Grid technology to achieve an effective provision of the relevant knowledge to the discussion process.…”

“…However, due to the complexity of the Computational Grid, the difficulty encountered in developing parallel applications is higher than in traditional parallel computing environments. Thus, in order to simplify the development of Grid-aware applications several highlevel programming frameworks have been proposed, among which is the Master-Worker Framework (MWF) [11].…”

The discussion process plays an important social task in Computer-Supported Collaborative Learning (CSCL) where participants can discuss about the activity being performed, collaborate with each other through the exchange of ideas that may arise, propose new resolution mechanisms, as well as justify and refine their own contributions and thus acquire new knowledge. Indeed, learning by discussion when applied to collaborative learning scenarios can provide significant benefits for students in collaborative learning, and in education in general. However, the discussion process in the context of distance education presents high dropout in comparison to traditional programs due chiefly to a sense of isolation of participants who do not have knowledge about others nor they can compare their own progress and performance to the group. To alleviate this problem, the provision of appropriate knowledge from the analysis of on-line interaction is rapidly gaining popularity due to its great impact on the discussion performance and outcomes. This implies a need to capture and structure all types of information generated by group activity and then to extract the relevant knowledge in order to provide participants with efficient awareness and feedback as regards group performance and collaboration. As a result, it is necessary to process and analyze complex event log files from group activity in a constant manner, and thus it may require computational capacity beyond that of a single computer. To this end, in this paper we show how a Grid approach can considerably increase the overall efficiency of processing group activity log files and thus allow discussion participants to receive effective knowledge even in real time.

“…The goal is to make it possible to both prepare information to facilitate its later processing and analysis and allow it to be efficiently addressed in a distributed environment where available (such as in a grid environment). Detailed information about how to structure and parallelize the processing of event log files can be found at Xhafa, Caballé, Daradoumis, and Zhou (2004) and Caballé, Paniagua, Xhafa, and Daradoumis (2005). This forms the second step of the process of embedding information and knowledge into collaborative learning applications (see Figure 2).…”

This study aims to explore the importance of efficient management of event information generated from group activity in collaborative learning practices for its further use in extracting and providing knowledge on interaction behavior. The essential issue here is how to design a platform that can be used for real, long-term, complex collaborative problem-solving situations and which enables the instructor to both analyze group interaction effectively and provide an adequate support when needed. The achievement of this task first involves the design of a conceptual model that structures and classifies the information generated in a collaborative learning application at several levels of description. This conceptual model is then translated into a computational model that not only allows the efficient management of the knowledge produced by the individual and group activity but also the possibility of exploiting this knowledge further as a meta-cognitive tool for real-time coaching and regulating the collaborative learning process. The computational model becomes the central issue in this contribution while the conceptual model is briefly introduced.

“…In order to facilitate this step, CSCL applications may structure this information as log files in a way that takes advantage of the parallelism in order to process several files (e.g. all the groups in a classroom) at the same time and thus dramatically reduce the overall computational time to process them [10], [11]. As a result, it is possible for these applications to process a large volume of collaboration activity data and make the extracted information available even in real time.…”

Abstract. This study aims to explore two crucial aspects of collaborative work and learning: the importance of enabling CSCL applications, on the one hand, to capture and structure the information generated by group activity and, on the other hand, to extract the relevant knowledge in order to provide learners and tutors with efficient awareness and support as regards collaboration. To this end, we first identify and define the main types of information generated in online group activity and then propose a process for efficiently embedding this information and the knowledge extracted from it into CSCL applications for awareness and feedback purposes. The conceptual model proposed finally gave rise to the design and implementation of a CSCL generic platform, called the Collaborative Learning Purpose Library (CLPL), which serves as a basis for the systematic development of collaborative learning applications and for providing full support to the mentioned process of knowledge management.
