CoSy Learning Lab


The Computer Supported Learning Engineering Laboratory -CoSy LLab- belongs to the Department of Technology Education and Digital Systems of the University of Piraeus, in Piraeus, Greece. The research unit was established in 2003 by Dr Symeon Retalis, Assistant Professor in the same department.

CoSy-LLab members conduct research in the broader area of e-learning with emphasis on the engineering aspect of e-learning.
Elearning Engineering is concerned with the establishment and use of systematic and formal principles, methods and technologies standards for the successful development, deployment and maintenance of high quality elearning systems and applications. The term “E-learning” signifies the use of networked computer environments and tools as well as open, flexible and active learning methods for education, training and lifelong learning.

We employ techniques from the fields of instructional design, hypermedia engineering, semantic web and human computer interaction. These techniques and methods include design patterns, conceptual modeling and component-based architectures for Adaptive Educational Hypermedia Systems and collaborative learning environments.

More recently we are working on the construction of a pattern language for elearning. Please visit the ELEN project and the TELL project web sites to learn more about this effort and to access the elearning patterns repository
