Gridcole: A tailorable grid service based system that supports scripted collaborative learning

摘要

This paper introduces Gridcole, a new system that can be easily tailored by educators in order to support the realization of scripted collaborative learning situations. To do so, educators can provide a script specifying the sequence of activities to be performed by learners as well as the tools and documents required to support them. Gridcole can then search for these tools in a service-oriented grid in order to integrate them so that they are available for users during the realization of the situation. Significantly, Gridcole has two features that are not supported by other tailorable systems. First, it allows the integration of tools that use supercomputing capabilities or specific hardware resources, thus enabling the possibility of supporting many situations in which this type of tools is required. Besides, Gridcole can guide learners during the realization of collaborative learning situations according to the sequences of activities specified in the scripts. This way, learners can benefit from the advantages of scripted collaborative learning. Gridcole has been evaluated using three collaborative learning situations conceived for real courses at university level. The results of the evaluation show that Gridcole does provide the desired properties concerning tool integration and activity guidance as well as that the proposed system can provide adequate support for a wide range of collaborative learning situations.
