    Structured evaluation of virtual environments for special-needs education

    This paper describes the development of a structured approach to evaluate experiential and communication virtual learning environments (VLEs) designed specifically for use in the education of children with severe learning difficulties at the Shepherd special needs school in Nottingham, UK. Constructivist learning theory was used as a basis for the production of an evaluation framework, used to evaluate the design of three VLEs and how they were used by students with respect to this learning theory. From an observational field study of student-teacher pairs using the VLEs, 18 behaviour categories were identified as relevant to five of the seven constructivist principles defined by Jonassen (1994). Analysis of student-teacher behaviour was used to provide support for, or against, the constructivist principles. The results show that the three VLEs meet the constructivist principles in very different ways and recommendations for design modifications are put forward

    Mobile technologies: prospects for their use in learning in informal science settings

    Recent developments in mobile technologies have offered the potential to support learners studying a variety of subjects. In this paper we explore the possibilities related to science learners and in particular focus on science learners in informal settings and reflect on a number of recent projects in order to consider the prospects for such work. The debate on informal learning acknowledges the complexity of the area and the difficulty of defining informal learning. One view is to consider the settings in which learning takes place as a continuum from formal settings, e.g. university, to social structures, e.g. friendship groups (Sefton-Green, 2004). The literature on science learning with mobile devices at this very 'informal' end of the spectrum is currently sparse and so in the paper we reflect on some projects and possibilities across the continuum. Our main focus is how mobile devices can support informal learning in science and research possibilities. Some of the recent research on mobile learning has used an activity theoretical perspective, including one of the case studies we discuss and in the final part of the paper we highlight the influence of activity theory in helping us to consider the complexity of the learning settings

    Roadmap on semiconductor-cell biointerfaces.

    This roadmap outlines the role semiconductor-based materials play in understanding the complex biophysical dynamics at multiple length scales, as well as the design and implementation of next-generation electronic, optoelectronic, and mechanical devices for biointerfaces. The roadmap emphasizes the advantages of semiconductor building blocks in interfacing, monitoring, and manipulating the activity of biological components, and discusses the possibility of using active semiconductor-cell interfaces for discovering new signaling processes in the biological world

    Using cultural probes to inform the design of assistive technologies

    Get PDF
    This paper discusses the practical implications of applying cultural probes to drive the design of assistive technologies. Specifically we describe a study in which a probe was deployed with home-based carers of people with dementia in order to capture critical data and gain insights of integrating the technologies into this sensitive and socially complex design space. To represent and utilise the insights gained from the cultural probes, we created narratives based on the probe data to enhance the design of assistive technologies.This work was supported by the Arts and Humanities Research Council (AH/K00266X/1) and RCUK through the Horizon Digital Economy Research grant (EP/G065802/1)
