    thesisConcept maps have been shown to have positive effects for students on recall. This is because, among other things, they are designed to show learners the relationships between concepts in a visuospatial way. However, it remains to be seen how concept maps affect deeper forms of learning, or whether it is the attention to the relationship between the concepts in the map or the concepts themselves that support the learning. This research examined the impact of the spatial organization of graphical search interfaces on deep learning as well as the impact of focusing student attention on the conceptual relationships between map nodes in this graphical search interface by asking them to generate information about those relationships. Results showed a nonsignificant trend suggesting that participants who were asked to generate information about the relationship between concepts showed greater recall when not learning from a concept map

    Youth and Digital Media: From Credibility to Information Quality

    Building upon a process-and context-oriented information quality framework, this paper seeks to map and explore what we know about the ways in which young users of age 18 and under search for information online, how they evaluate information, and how their related practices of content creation, levels of new literacies, general digital media usage, and social patterns affect these activities. A review of selected literature at the intersection of digital media, youth, and information quality -- primarily works from library and information science, sociology, education, and selected ethnographic studies -- reveals patterns in youth's information-seeking behavior, but also highlights the importance of contextual and demographic factors both for search and evaluation. Looking at the phenomenon from an information-learning and educational perspective, the literature shows that youth develop competencies for personal goals that sometimes do not transfer to school, and are sometimes not appropriate for school. Thus far, educational initiatives to educate youth about search, evaluation, or creation have depended greatly on the local circumstances for their success or failure

    Online participation: the Woodberry Down experiment

    The internet and world wide web are generating radical changes in the way we are able tocommunicate. Our ability to engage communities and individuals in designing theirenvironment is also beginning to change as new digital media provide ways in whichindividuals and groups can interact with planners and politicians in exploring their future.This paper tells the story of how the residents of one of the most disadvantagedcommunities in Britain ? the Woodberry Down Estate in the London borough ofHackney ? have begun to use an online system which delivers everything from routineservices about their housing to ideas about options for their future. Woodberry Down isone of the biggest regeneration projects in Western Europe. It will take at least 10 years,probably much longer, to complete, at a cost of over ÂŁ150 million. Online participation isone of the many ways in which this community is being engaged but as we will show, itis beginning to act as a catalyst. The kinds of networks which are evolving aroundsystems like these will change the nature of participation itself, the ways we need to thinkabout it, and the ways we need to respond. Before the experiment is described, we set thecontext by describing the wide range of digital media for communicating plans andplanning which suggests a new typology for web participation consistent with this fastemerging network culture

    Cyberspace As/And Space

    The appropriate role of place- and space-based metaphors for the Internet and its constituent nodes and networks is hotly contested. This essay seeks to provoke critical reflection on the implications of place- and space-based theories of cyberspace for the ongoing production of networked space more generally. It argues, first, that adherents of the cyberspace metaphor have been insufficiently sensitive to the ways in which theories of cyberspace as space themselves function as acts of social construction. Specifically, the leading theories all have deployed the metaphoric construct of cyberspace to situate cyberspace, explicitly or implicitly, as separate space. This denies all of the ways in which cyberspace operates as both extension and evolution of everyday spatial practice. Next, it argues that critics of the cyberspace metaphor have confused two senses of space and two senses of metaphor. The cyberspace metaphor does not refer to abstract, Cartesian space, but instead expresses an experienced spatiality mediated by embodied human cognition. Cyberspace in this sense is relative, mutable, and constituted via the interactions among practice, conceptualization, and representation. The insights drawn from this exercise suggest a very different way of understanding both the spatiality of cyberspace and its architectural and regulatory challenges. In particular, they suggest closer attention to three ongoing shifts: the emergence of a new sense of social space, which the author calls networked space; the interpenetration of embodied, formerly bounded space by networked space; and the ways in which these developments alter, instantiate, and disrupt geographies of power

    ImpaCT2: pupils' and teachers' perceptions of ICT in the home, school and community

    Get PDF
    The Strand 2 report of the ImpaCT 2 research describes the results of applying a range of research methods to explore, how pupils use ICT, in particular out of school and what had been gained from this use. ImpaCT2 was a major longitudinal study (1999-2002) involving 60 schools in England, its aims were to: identify the impact of networked technologies on the school and out-of-school environment; determine whether or not this impact affected the educational attainment of pupils aged 8 - 16 years (at Key Stages 2, 3, and 4); and provide information that would assist in the formation of national, local and school policies on the deployment of ICT

    Automatic Annotation of Images from the Practitioner Perspective

    No full text
    This paper describes an ongoing project which seeks to contribute to a wider understanding of the realities of bridging the semantic gap in visual image retrieval. A comprehensive survey of the means by which real image retrieval transactions are realised is being undertaken. An image taxonomy has been developed, in order to provide a framework within which account may be taken of the plurality of image types, user needs and forms of textual metadata. Significant limitations exhibited by current automatic annotation techniques are discussed, and a possible way forward using ontologically supported automatic content annotation is briefly considered as a potential means of mitigating these limitations
