    Issues in Reusing Online Resources: Chapter 1

    This is an era marked by rapid developments in three different educational arenas -- access, lifelong learning and e-learning. In both developed and developing countries there is a growing demand for access to education... Alongside this growing demand for access, increased numbers of adults are returning to colleges and universities for additional education and training (CIHE, 2002). Lifelong learning has come of age, brought about by changes in attitudes to learning and in employment patterns, where jobs and careers are recast many times during a lifespan. Permeating and supporting these first two developments, in access and lifelong learning, are developments in information and communication technologies (ICT). New technologies are beginning to transform how higher education is organized and delivered both on campus and at a distance. E-learning affords new opportunities to increase flexibility in time and location of study, in forms of communication (for example, asynchronous discussions) and types of interaction... Although e-learning has the potential to provide the kinds of flexibility required by wider access and lifelong learning there are some major obstacles. On the one hand, wider access and lifelong learning require vast increases in specially designed course materials to satisfy the greater range of demands for learning. On the other hand, creating the digital resources necessary for online course delivery requires considerable investment, a factor that makes resource development only viable for courses with large student numbers or sizeable budgets. In order to address this difficulty, numerous national and international initiatives have been funded to investigate ways in which digital learning resources might be developed, shared and reused by teachers and learners around the world (so as to benefit from economies of scale). Behind these initiatives lies a vision of a future in which reusable resources (or 'learning objects' as they are called) could comprise a new currency of exchange within a learning economy. Learning objects, produced by publishers, teachers, support staff and students themselves, would be stored in digital repositories, where they could be easily accessed, recombined and reused within online courses. However, despite this vision, the idea of reusing electronic resources is more complex than the object economy scenario, outlined above, may suggest. The next section identifies seven issues associated with the reuse and sharing of resources. These sections focus on educational design, the need for standards, and on the culture and organization that would be necessary in institutions (and across institutions) if reuse were to become a reality

    Adiabatic motion of a neutral spinning particle in an inhomogeneous magnetic field

    The motion of a neutral particle with a magnetic moment in an inhomogeneous magnetic field is considered. This situation, occurring, for example, in a Stern-Gerlach experiment, is investigated from classical and semiclassical points of view. It is assumed that the magnetic field is strong or slowly varying in space, i.e., that adiabatic conditions hold. To the classical model, a systematic Lie-transform perturbation technique is applied up to second order in the adiabatic-expansion parameter. The averaged classical Hamiltonian contains not only terms representing fictitious electric and magnetic fields but also an additional velocity-dependent potential. The Hamiltonian of the quantum-mechanical system is diagonalized by means of a systematic WKB analysis for coupled wave equations up to second order in the adiabaticity parameter, which is coupled to Planck’s constant. An exact term-by-term correspondence with the averaged classical Hamiltonian is established, thus confirming the relevance of the additional velocity-dependent second-order contribution

    Flexible delivery: A model for analysis and implementation of flexible programme delivery

    The approach to quality and standards in Scotland is enhancement-led and learner-centred. It was developed through a partnership of the Scottish Funding Council (SFC), Universities Scotland, the National Union of Students in Scotland (NUS Scotland) and the Quality Assurance Agency for Higher Education (QAA) Scotland. The Higher Education Academy has also joined that partnership. The Enhancement Themes are a key element of a five-part framework which has been designed to provide an integrated approach to quality assurance and enhancement, supporting learners and staff at all levels in enhancing higher education in Scotland drawing on developing, innovative practice within the UK and internationally. The five elements of the framework are: * a comprehensive programme of subject-level reviews undertaken by the higher education institutions themselves; guidance on internal reviews is published by SFC (www.sfc.ac.uk) * enhancement-led institutional review (ELIR) run by QAA Scotland (www.qaa.ac.uk/reviews/ELIR) * improved forms of public information about quality; guidance on the information to be published by higher education institutions is provided by SFC (www.sfc.ac.uk) * a greater voice for students in institutional quality systems, supported by a national development service - student participation in quality scotland (sparqs) (www.sparqs.org.uk) * a national programme of Enhancement Themes aimed at developing and sharing good practice to enhance the student learning experience, which are facilitated by QAA Scotland (www.enhancementthemes.ac.uk). The topics for the Themes are identified through consultation with the sector and implemented by steering committees whose members are drawn from the sector and the student body. The steering committees have the task of developing a programme of development activities, which draw upon national and international good practice. Publications emerging from each Theme are intended to provide important reference points for higher education institutions in the ongoing strategic enhancement of their teaching and learning provision. Full details of each Theme, its steering committee, the range of research and development activities, and the outcomes are published on the Enhancement Themes website (www.enhancementthemes.ac.uk). To further support the implementation and embedding of a quality enhancement culture within the sector, including taking forward the outcomes of the various Enhancement Themes, a new overarching committee has been established, chaired by Professor Kenneth Miller (Vice-Principal, University of Strathclyde). It has the important dual role of supporting the overall approach of the enhancement themes, including the five-year rolling plan, and of supporting institutional enhancement strategies and management of quality. We very much hope that the new committee, working with the individual topic-based Themes' steering committees, will provide a powerful vehicle for the progression of the enhancement-led approach to quality and standards in Scottish higher education

    Moore's Paradox and Assertion

    If I were to say, “Agnes does not know that it is raining, but it is,” this seems like a perfectly coherent way of describing Agnes’s epistemic position. If I were to add, “And I don’t know if it is, either,” this seems quite strange. In this chapter, we shall look at some statements that seem, in some sense, contradictory, even though it seems that these statements can express propositions that are contingently true or false. Moore thought it was paradoxical that statements that can express true propositions or contingently false propositions should nevertheless seem absurd like this. If we can account for the absurdity, we shall solve Moore’s Paradox. In this chapter, we shall look at Moore’s proposals and more recent discussions of Moorean absurd thought and speech
