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)
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)
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)
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)
This paper presents the results of a study on group interaction with a prototype known as socio-ec(h)o. socio-ec(h)o explores the design of sensing and display, user modeling, and interaction in an embedded interaction system utilizing a game structure. Our study involved the playing of our prototype system by thirty-six (36) participants grouped into teams(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. However, the underlying social processes that contribute to(More)
Feature Models encapsulate functionalities and quality properties of a product family. The employment of feature models for managing variability and commonality of large-scale product families raises an important question: on what basis should the features of a product family be selected for a target software application, which is going to be derived from(More)
The paradigms of Service Oriented Architecture (SOA) and Software Product Line Engineering (SPLE) facilitate the development of families of software-intensive products. Software Product Line practices can be leveraged to support the development of service-oriented applications to promote the reusability of assets throughout the iterative and incremental(More)
