For more than ten years, Communities of Practice (CoPs) have been recognized as effective environments to support learning by professionals, organisations and educational institutions. Collaborative learning is inherent in such communities, in that their members learn from each other by making their knowledge and practices explicit, sharing them with their peers, and reflecting on them. This panel aims at discussing the interaction between learning processes and Communities of Practice, along three dimensions: (i) studying learning processes in CoPs; (ii) using Communities of Practice for fostering, sustaining and tutoring authentic learning activities; (iii) including Communities of Practice awareness in training to foster the further building of Communities of Practice.
