A Grid based software architecture for delivery of adaptive and personalised learning experiences

This paper is centred on one of the main results of the ELeGI project, namely its software architecture for the delivery of personalised formal-learning experiences. The architecture has been designed and developed: i) taking into account a general model for the personalisation of learning experiences, allowing us to obtain a solution that is flexible with respect to the pedagogies, and ii) on top of Service Oriented Grid technologies, allowing us to obtain several advantages in the process of creation and delivery of personalised learning experience like, for instance, ubiquitous and seamless access to heterogeneous learning resources distributed over the network. In order to validate our result, the first prototype of the ELeGI architecture has been deployed on a Virtual Organisation consisting of three geographically distributed nodes. Each node of the VO provides services and learning resources that have been adopted in the creation and delivery of a personalised learning experience about the Torricelli’s law and based on the Virtual Scientific Experiment model. The case of study has been successfully executed and has given us a proof of our assumptions related to the added value of the Service Oriented Grid mainly in terms of: i) capabilities to access educational resources distributed over the network, that is relevant in achieving the personalisation of learning experiences, and ii) high level of dynamicity and adaptiveness in the creation and delivery processes of a personalised learning experience.
