Abstract
The paper describes our proposal for adopting 3D spatial representation, based on suitable indications and metrics, for the evaluation of experiences conducted in a Personal Learning Environment (PLE) and its social extension, the Personal Learning Network (PLN).
The use of 3D space is a mean for integrating different perspectives (e.g., structured and non-structured learning) but also to foster the cooperation between users. Moreover, information coming from the use of 3D space can represent a precious feedback for better understanding ongoing learning activities, but it will be extremely useful for enhancing and improving the development of existing PLE-PLN support tool.
