Project Title

Creation and sharing of collaborative learning designs within the Open Educational Resources cycle.

Project Summary

Yannis Dimitriadis was the first OLnet fellow and visited the Open University, UK, near the start of the project.  Yannis was part funded by OLnet and part by University of Valladolid. Yannis came to OLnet with an established expertise in pedagogic patterns that he was then able to apply to the field of OER. He worked with Gráinne Conole on the way in which patterns can feed into designs for OER.

The work recognised how OER provided examples (or Mediating Artefacts) to help people understand designs and then how patterns could be used to help inspire those who were trying to make use of OER. As part of his fellowship an approach was piloted that takes established patterns for collaborative learning and uses this to generate new activities based on OER, i.e. to re-purpose existing OER so that they could be used in collaborative learning contexts. This approach has been used as the basis for a series of workshops to communicate and test the ideas.

An output was a very successful workshop "Collaborative patterns and design for OER: new approaches to improve the design and reuse of resources", which took place on 30 June 2009.

Biographic information

Yannis A Dimitriadis is currently a Full Professor of Telematics Engineering, at the Telecommunications Engineering School, University of Valladolid, where he is heading a multidisciplinary team (GSIC/EMIC: Group of Intelligent and Cooperative Systems/Education, Media, Information and Culture) on Technology-Enhanced Learning.

The GSIC/EMIC members come from the fields of Telecommunications Engineering, Computer Science, and Pedagogy and they are mainly devoted to research in: the design and development of underlying technologies for e-learning applications (middleware and the semantic annotation of e-learning resources, among others); the role and the needed technological support for educators as designers of customized e-learning applications; the educative evaluation of the effectiveness of e-learning; and the educational advantages and technological requirements of collaborative technology-enhanced learning or Computer-Supported Collaborative Learning (CSCL).

One of his main activities deals with interaction analysis in CSCL environments, with specific contributions with respect to a mixed evaluation method, the computational model for interactions, a role-based framework, as well as multiple real case studies. He has participated in the e-learning TELL project that studied the effectiveness of CSCL, as well as in several Kaleidoscope projects on interaction analysis, besides the eContentPlus project Share.TEC on federated repositories of resources for Teacher Educators.

Dr. Dimitriadis received the B.S. degree from the National Technical University of Athens, Greece, in 1981, the M.S. degree from the University of Virginia, Charlottesville, in 1983, and the Ph. D. degree from the University of Valladolid, Spain, in 1992, all in telecommunications engineering.

Main Output

Evidence was gathered regarding re-purposing of OER for CSCL. The workshop that was carried out in the final part of the stay reinforced the claim about the power of pedagogical patterns as mediating artefacts for learning design.

Update Since Fellowship

Taking into account that the main personal expertise was on collaborative learning and pedagogical patterns, the stay increased the awareness of the issues and connections to the OER field. Several local activities at Valladolid were carried out with respect to the use of OER and their use in the context of CSCL, while significant work has been done in the framework of the European Share.TEC project.
