Improving Role Taking in CSCL Script Using SNA and Semantic Web

Designing effective CSCL processes is a complex task that can be supported by existing good practices formulated as pedagogical patterns or script. Over the past years the TEE research has shown that CSCL script acts as Mediating Artifacts (MA) designing educational scenarios and structuring and prescribing roles and activities. This work proposes an approach, based on Social Network Analysis and Semantic Web, in order to improve definition and instantiation phases of IMS-LD scripts.
