    Making physical education relevant: Increasing the impact of initial teacher training

    This paper is developed from concern that, despite a number of developments and initiatives in physical education over recent years, there has been little change in the teaching of the subject. This has resulted in many young people being alienated from physical education and therefore physical activity. The paper focuses on how initial teacher training (ITT) contributes to this lack of change by focusing on the development of knowledge for teaching and the technical competence to deliver this. It then considers ways in which ITT could contribute to developing ‘knowledgeable teachers’ who are able to make change. The paper focuses on two aspects identified as relevant for trainee physical education teachers: socialisation and knowledge for teaching. It recognises that the issues are complex and that change is difficult. It also recognises that ITT cannot change things by itself. However, it argues that by maintaining the status quo, the subject will not develop so that it is relevant to today’s youngsters

    OpenPING: A Reflective Middleware for the Construction of Adaptive Networked Game Applications

    The emergence of distributed Virtual Reality (VR) applications that run over the Internet has presented networked game application designers with new challenges. In an environment where the public internet streams multimedia data and is constantly under pressure to deliver over widely heterogeneous user-platforms, there has been a growing need that distributed VR applications be aware of and adapt to frequent variations in their context of execution. In this paper, we argue that in contrast to research efforts targeted at improvement of scalability, persistence and responsiveness capabilities, much less attempts have been aimed at addressing the flexibility, maintainability and extensibility requirements in contemporary distributed VR platforms. We propose the use of structural reflection as an approach that not only addresses these requirements but also offers added value in the form of providing a framework for scalability, persistence and responsiveness that is itself flexible, maintainable and extensible. We also present an adaptive middleware platform implementation called OpenPING1 that supports our proposal in addressing these requirements

    Interoperating with heterogeneous Mobile Services

    Mobile applications are now developed upon a wide range of service development platforms, commonly referred to as middleware. However, the diversity of those available presents a problem for mobile client development. How can a single client implementation interoperate with heterogeneous service implementations
