New systems are designed with improved quality or features. However, not every new system lives to its pre-development expectations when tested with end-users. The evaluation of the first version of our LOCO-Analyst tool for providing teachers with feedback on students learning activities and performance led to the enhancing the visualization features of(More)
Interoperability is one of the main issues in creating a networked system of repositories The approaches range from simply forcing one metadata standard on all participating repositories to highly sophisticated semantic web based architectures with full semantic mapping capabilities between different schemas. The eduSource project in its holistic approach(More)
It is widely accepted that the social capital of students – developed through their participation in learning communities – has a significant impact on many aspects of the students' learning outcomes, such as academic performance, persistence, retention, program satisfaction and sense of community.

Context: A Software Product Line is a family of software systems that share some common features but also have significant variabilities. A feature model is a variability modeling artifact, which represents differences among software products with respect to the variability relationships among their features. Having a feature model along with a reference(More)
Mobile devices could facilitate human interaction and access to knowledge resources anytime and anywhere. With respect to wide application possibilities of mobile learning, investigating learners' acceptance towards it is an essential issue. Based on activity theory approach, this research explores positive factors for the acceptance of m-learning systems.(More)
This paper explores the design issues of situated play within a museum through the study of a museum guide prototype that integrates a tangible interface, audio display, and adaptive modeling. We discuss our use of design ethnography in order to situate our interaction and to investigate the liminal and engagement qualities of a museum visit. The paper(More)
The idea of knowledge sharing has strong roots in the education process. With the current development of the technology and moving learning material into the web environment it acquired a new dimension. Learning objects are the chunks of knowledge shared by e-learning community. Organizations and individuals are building repositories of learning objects and(More)
In this paper we describe an ontology and rule based system that significantly increases the productivity of those who create metadata, and the quality of the metadata they produce. The system suggests values for metadata elements using a combination of four methods: inheritance, aggregation, content based similarity and ontology-based similarity. Instead(More)
