Over the past years the concept of role in distance education has become a promising construct for analyzing and facilitating collaborative processes and outcomes. It is widely acknowledged that in the CSCL research field the spontaneous collaboration does not necessarily lead learners to play functional and complementing roles that can foster group discussion, knowledge sharing and argumentation. In order to obviate this difficulty, the scientific community has recently developed and sustained the validity of CSCL scripts and scripted roles perspective focusing on how collaborative learning process can be facilitated by designing educational scenarios and structuring and prescribing roles and activities. Nowadays, educational systems are not able to provide dynamic role management in the definition and execution of CSCL scripts. This work proposes the application of Social Network Analysis (SNA) in order to evaluate the expertise level of a learner when he/she is acting, with an assigned role, within the execution of a CSCL script. Extensions to IMS-LD (to enrich its roles management using the SIOC ontology) and to IMS-LIP (to support CSCL roles) are provided.

Abstract
Over the past years the concept of role in distance education has become a promising construct for analyzing and facilitating collaborative processes and outcomes. It is widely acknowledged that in the CSCL research field the spontaneous collaboration does not necessarily lead learners to play functional and complementing roles that can foster group discussion, knowledge sharing and argumentation. In order to obviate this difficulty, the scientific community has recently developed and sustained the validity of CSCL scripts and scripted roles perspective focusing on how collaborative learning process can be facilitated by designing educational scenarios and structuring and prescribing roles and activities. Nowadays, educational systems are not able to provide dynamic role management in the definition and execution of CSCL scripts. This work proposes the application of Social Network Analysis (SNA) in order to evaluate the expertise level of a learner when he/she is acting, with an assigned role, within the execution of a CSCL script. Extensions to IMS-LD (to enrich its roles management using the SIOC ontology) and to IMS-LIP (to support CSCL roles) are provided.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
