Nikos Palavitsinis PhD dissertation

Last Friday, 21st of February, IE doctorate student and AgroKnow member Nikos Palavitsinis successfully presented his thesis METADATA QUALITY ISSUES IN LEARNING REPOSITORIES. The formal defense of the dissertation took place in the ancient Colegio de San Ildefonso of the University of Alcala, a beautiful baroque building currently hosting the Rectorate.

Nikos research work, supervised by IE member Salvador Sanchez and Dr. Nikos Manouselis, aimed to propose a set of methods that can be deployed throughout the life cycle of a repository to ensure that metadata generated from content providers are of high quality. The theoretical model (named MQACP for short) was applied on a Learning Federation of repositories, from day 1 of its existence until it reached its maturity and regular operation. Throughout each phase, the resulting metadata quality was measured to certify that the anticipated improvement in metadata quality actually took place. Based on the success of this first application, Nikos decided to validate the MQACP approach by applying it on another two cases of a Cultural and a Research Federation of repositories: VOA3R and Natural Europe, which allowed to prove the transferability of the approach to other cases as well as to present some similarities with the initial one.

It was a happy day for the whole IE team, many of whose members attended the dissertation (Enayat Rajabi, Rutilio Lopez, Paulo Alonso and David Marting among others). In the pictures below these lines, some moments of the day.

Successful PhD dissertation to close the year

Friday 20th of december, IE doctorate student Alejandra Segura presented her thesis defense in the Rectorate building of the University of Alcala. This research work, supervised by IE member Salvador Sanchez and Manuel E. Prieto from the University of Castilla la Mancha, aimed to propose a strategy for query expansion based on domain ontologies. According to this work, it is possible to find an strategy allowing instructional designers to find objects in a repository relevant enough as to be reused in the design of new courses or in the composition of new, more complex resources. To achieve this goal, proposals of query expansions both in the field of information retrieval in general or specifically on learning object repositories were analyzed.

For the purpose of evaluation, an experiment in the area of genetics was designed. This experiment used the Gene Ontology as a knowledge base and the MERLOT repository as a provider of learning objects in this domain.

PhD dissertation in Salamanca

IE member Salvador Sanchez has been invited to be part of the review board of a PhD dissertation supervised by Francisco Garcia Peñalvo, leader of the GRIAL research group at University of Salamanca. The PhD thesis by Hector Barbosa, a Mexican lecturer working in GRIAL’s research projects, presented Adasat, an automated generator of QTI-compliant tests. This tool generates personalized tests depending on the learner’s learning styles and preferences.

It’s veeeery cold in Salamanca these days (during the night, it cools off to -5ºC !) but the warmth welcome by our Salamanca friends, the beautiful university city of Salamanca and the nice research work finished helps to warm up. Below, a shot taken from Francisco’s desk. Everybody wish to had this view from their desks!

Javier Sanz Ph.D dissertation

Last monday IE members Miguel Angel Sicilia and Salvador Sanchez attended to the Ph.D dissertation of Javier Sanz. Javier’s work on learning object metrics, supervised by Salvador and Juan Manuel Dodero from University of Cadiz, has been positively acclaimed by the community: this was just the last hurdle to overcome.

Professors from University of Alcala, other universities in Spain (Cadiz, Carlos III of Madrid) and Escuela Superior Politécnica del Litoral (Guayaquil, Ecuador) formed the board of assessors for the dissertation.

After the successful event, supervisors, assessors and the new Ph.D had lunch together in the restaurant inside El Parador of Alcala.
