gory, children constructed a pair of maps: one without links and one with links. Forty-four maps were analyzed to identify similarities and differences. The structures of the maps were compared to the structures employed by the directories. Children were able to construct hierarchical maps and articulate the relationships among the concepts. At the global level (whole map), children's maps were...

Visual analytics is a new interdisciplinary field of study that calls for a more structured scientific approach to understanding the effects of interaction with complex graphical displays on human cognitive processes. Its primary goal is to support the design and evaluation of graphical information systems that better support cognitive processes in areas as diverse as scientific research and em...

The acquisition of conceptual knowledge is a central aim in science education. In this study, an interdisciplinary hypermedia-media assisted learning unit about hibernation and thermodynamics was developed and evaluated. But the assessment of interdisciplinary knowledge is not trivial. Therefore, concept mapping procedures were used to assess the cognitive effects within this complex knowledge ...

Learning Content Management System (LCMS) supports e-learning applications with storage and efficient access for e-Learning Objects (LOs). In order to foster LCMS adoption by the e-learning community, an important issue is to bring course modelling to the realm of the LCMS. In this paper, we describe the Repository of Objects with Semantic Access (ROSA) project. ROSA is a LCMS that provides use...

Over the last two decades, there have been many high profile success stories where cutting edge computer graphics (CG) technology was used in collaboration with cultural heritage (CH) professionals to unlock the secrets of humanity’s legacy. Well known examples include the empirical 3D acquisition of Michelangelo’s David, the laser scan-based 3D mapping of the tombs found in the Valley of the K...

This poster reports on current work with the NSF-funded Achievement Standards Network (ASN) to support discovery of educational resources in digital libraries using conceptual graphs of officially promulgated achievement standards statements. Conceptual graphs or knowledge maps of achievement standards reveal the macrostructure of the learning domain modeled by those standards and support highe...

Designed for and evaluated by computer science researchers, medical doctors and civil and mechanical engineers, the Collaborative Decision Making (CDM) tool HERMES (Karacapilidis and Papadias, 1998, 2001) is about to be adapted for another kind of audience, i.e. the communities of practices (CoPs) under the name “COPE_IT!” (http://copeit.cti.gr/) and currently developed in the framework of the ...
