Research and design challenges for developing personalised eLearning systems

While E-learning technologies are continuously developing, there are number of emerging issues and challenges that have significant impact on e-learning research and design. These include educational, technological, sociological, and psychological viewpoints. The extant literature points out that a large number of existing E-learning systems have problems with offering reusable, personalized and learner-centric content. While developers are placing emphasis on the technology aspects of e-learning, critical conceptual and pedagogical issues are often ignored. This paper will reports on our research in design and development of personalised e-learning systems and some of the challenges and issues faced.

Multiphysics modelling for electronics design

The future of many companies will depend to a large extent on their ability to initiate techniques that bring schedules, performance, tests, support, production, life-cycle-costs, reliability prediction and quality control into the earliest stages of the product creation process. Important questions for an engineer who is responsible for the quality of electronic parts such as printed circuit boards (PCBs) during design, production, assembly and after-sales support are: What is the impact of temperature? What is the impact of this temperature on the stress produced in the components? What is the electromagnetic compatibility (EMC) associated with such a design? At present, thermal, stress and EMC calculations are undertaken using different software tools that each require model build and meshing. This leads to a large investment in time, and hence cost, to undertake each of these simulations. This paper discusses the progression towards a fully integrated software environment, based on a common data model and user interface, having the capability to predict temperature, stress and EMC fields in a coupled manner. Such a modelling environment used early within the design stage of an electronic product will provide engineers with fast solutions to questions regarding thermal, stress and EMC issues. The paper concentrates on recent developments in creating such an integrated modeling environment with preliminary results from the analyses conducted. Further research into the thermal and stress related aspects of the paper is being conducted under a nationally funded project, while their application in reliability prediction will be addressed in a new European project called PROFIT.

Research in statistical education — planning of an international survey

As announced in the November 2000 issue of MathStats&OR [1], one of the projects supported by the Maths, Stats & OR Network funds is an international survey of research into pedagogic issues in statistics and OR. I am taking the lead on this and report here on the progress that has been made during the first year. A paper giving some background to the project and describing initial thinking on how it might be implemented was presented at the 53rd session of the International Statistical Institute in Seoul, Korea, in August 2001 in a session on The future of statistics education research [2]. It sounded easy. I considered that I was something of an expert on surveys having lectured on the topic for many years and having helped students and others who were doing surveys, particularly with the design of their questionnaires. Surely all I had to do was to draft a few questions, send them electronically to colleagues in statistical education who would be only to happy to respond, and summarise their responses? I should have learnt from my experience of advising all those students who thought that doing a survey was easy and to whom I had to explain that their ideas were too ambitious. There are several inter-related stages in survey research and it is important to think about these before rushing into the collection of data. In the case of the survey in question, this planning stage revealed several challenges. Surveys are usually done for a purpose so even before planning how to do them, it is advisable to think about the final product and the dissemination of results. This is the route I followed.

Case-based retrieval of 3-dimensional shapes for the design of metal castings

This paper describes research into retrieval based on 3-dimensional shapes for use in the metal casting industry. The purpose of the system is to advise a casting engineer on the design aspects of a new casting by reference to similar castings which have been prototyped and tested in the past. The key aspects of the system are the orientation of the shape within the mould, the positions of feeders and chills, and particular advice concerning special problems and solutions, and possible redesign. The main focus of this research is the effectiveness of similarity measures based on 3-dimensional shapes. The approach adopted here is to construct similarity measures based on a graphical representation deriving from a shape decomposition used extensively by experienced casting design engineers. The paper explains the graphical representation and discusses similarity measures based on it. Performance measures for the CBR system are given, and the results for trials of the system are presented. The competence of the current case-base is discussed, with reference to a representation of cases as points in an n-dimensional feature space, and its principal components visualization. A refinement of the case base is performed as a result of the competence analysis and the performance of the case-base before and after refinement is compared.

Law in the community: the University of Greenwich/Greenwich Association of Disabled People Centre for Independent Living (GAD) research project

The GAD Advocacy Service is funded by the London Borough of Greenwich Directorate of Neighbourhood Services; its remit to support disabled people experiencing Hate Crime, Domestic Violence and Harassment. Run by disabled personnel and giving advice to all disabled people it is unique in London. Since its inception in 2004, the Advocacy Service has been stretched to its limit - there is a need to extend the remit of the Advocacy Service to give specialist legal advice on other issues. In 2003, the CEDRM-UK project was set up in the University of Greenwich Law Department as part of the Disability Rights Promotion International Legal Education and Research Project; its objectives were firstly, to facilitate the collection of data on the effectiveness of legislation in promoting the rights of disabled persons; and secondly, to pilot new methods in teaching and training in Human Rights Law – students acquire an expertise in Human Rights Law through research into the practical application of legislation relating to civil and human rights in the daily life of the community. In July 2007, GAD and CEDRM-UK embarked on a joint project to report on the work of the Advocacy Service and to create a database to support its caseload. The 2008-9 Project team will report on their work and findings relating to facilitating equality in the workplace; the inclusion of cancer, HIV and multiple sclerosis within the legal definition of disability and the implications of the statutory duty to promote disability equality for the provision of extracurricular activities for schoolchildren.

The varieties of student experience - an open research question and some ways to answer it

Based on meetings of the Society for Research into Higher Education’s Student Experience Network over the past three years, the genuinely open research question is posed whether there is one or more undergraduate student experience within English higher education. Answering this question depends on whether what is taught or what is learnt is examined. If the latter, then a unitary student experience can be said to exist only in the narrowest of normative senses. What undergraduates actually learn – defined in the widest sense – is the $64,000 question of research on the student experience. Various ways to answer this question are proposed, including using students to research students. Conceptual tools to apply to findings can be developed from youth studies and cognate disciplines, particularly in relation to student identities and aspirations. Lastly, these proposals are placed in the wider context of comparative models of the varieties of student experience, including those emerging in the UK’s national regions.
