COOPER is an EU funded collaborative specific targeted research project from the sixth framework programme of the Information Society Technologies IST (contract No. FP6 IST - 027073) that was officially launched on 1 December 2005. The COOPER project is dedicated to supporting long-distance cooperation of teams of students working on complex projects, assuming that the students and advisors are geographically dispersed and have heterogeneous backgrounds and competencies. COOPER applies to the following learning environments: ? Graduate (or post-graduate) university studies involving students and lecturers participating in focused projects (e.g., masters or specialization courses) coming from different institutions and backgrounds; ? Company universities and company training, involving multi-national participants coming from company?s sites or customers which are world-wide dispersed, participating in the launching of new product or technology, or in product- and project-centred training. Stemming from these requirements, COOPER?s main technological objective is to develop and test a model-driven, extensible environment that supports in Bdividual and collective competency building in virtual teams, whose members are geographically dispersed, have different backgrounds and competencies, working together in projects to solve complex problems.
