Adaptive reuse of Libre software systems for supporting on-line collaboration

In this paper, the adaptive reuse of Plone; an open source content management system is described. In one instance, Plone has been used as the backbone of a collaboration and communication support infrastructure within a large research project. In the other, Plone has been used as the main web-presence of a specialist group of the British Computer Society. This paper analyses the benefits and problems of reusing Plone to support collaboration. Based on this reuse experience, a more systematic approach to supporting Plone reuse is proposed. This approach takes into account the special case of reuse support relevant to open source software developments

Supporting sustainable e‐learning

This paper draws upon work carried out within phase one of a national forum for support staff, funded by the UK Learning and Teaching Support Network Generic Centre. It sets out themes in current Learning Technology research within the context of institutional practice. It reports the responses of a range of e‐learning support staff to new developments in the reuse and sharing of Learning Objects. The article highlights tensions across support units, inconsistencies in support provision and confusion over issues concerning different modes of teaching. It also forewarns a growing gap between institutional practice and research in the development of approaches to sustainable e‐learning

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

Knowledge-based reusable software synthesis system

The Eli system, a knowledge-based reusable software synthesis system, is being developed for NASA Langley under a Phase 2 SBIR contract. Named after Eli Whitney, the inventor of interchangeable parts, Eli assists engineers of large-scale software systems in reusing components while they are composing their software specifications or designs. Eli will identify reuse potential, search for components, select component variants, and synthesize components into the developer's specifications. The Eli project began as a Phase 1 SBIR to define a reusable software synthesis methodology that integrates reusabilityinto the top-down development process and to develop an approach for an expert system to promote and accomplish reuse. The objectives of the Eli Phase 2 work are to integrate advanced technologies to automate the development of reusable components within the context of large system developments, to integrate with user development methodologies without significant changes in method or learning of special languages, and to make reuse the easiest operation to perform. Eli will try to address a number of reuse problems including developing software with reusable components, managing reusable components, identifying reusable components, and transitioning reuse technology. Eli is both a library facility for classifying, storing, and retrieving reusable components and a design environment that emphasizes, encourages, and supports reuse

Reusable e-learning development: Case studies, practices and issues of awareness for knowledge-based organisations

Reusable e-learning development (RED) is defined as the cloning, modification and customisation of existing files or source codes for developing another website or another web-based application. RED does not imply just copying and changing existing files or source codes but rather, it provides a practical technique for time-saving, improving efficiency and maximising utility of existing resources for creating another website or another web-based application. RED is particularly useful for a large-scale web development, where there is an extremely high degree of overlapping of information, resources and web designs. Therefore, RED has been widely adopted by many knowledge-based organisations (KBO). In order to investigate the impacts of RED on KBO, various case studies, practices and issues of awareness for KBO are presented and analysed. This paper particularly focuses on studies and recommended practices from the University of Cambridge. Results from these case studies reveal a number of outcomes

Supporting collaboration within the eScience community

Collaboration is a core activity at the heart of large-scale co- operative scientific experimentation. In order to support the emergence of Grid-based scientific collaboration, new models of e-Science working methods are needed. Scientific collaboration involves production and manipulation of various artefacts. Based on work done in the software engineering field, this paper proposes models and tools which will support the representation and production of such artefacts. It is necessary to provide facilities to classify, organise, acquire, process, share, and reuse artefacts generated during collaborative working. The concept of a "design space" will be used to organise scientific design and the composition of experiments, and methods such as self-organising maps will be used to support the reuse of existing artefacts. It is proposed that this work can be carried out and evaluated in the UK e-Science community, using an "industry as laboratory" approach to the research, building on the knowledge, expertise, and experience of those directly involved in e-Science

FLAX: Flexible and open corpus-based language collections development

In this case study we present innovative work in building open corpus-based language collections by focusing on a description of the opensource multilingual Flexible Language Acquisition (FLAX) language project, which is an ongoing example of open materials development practices for language teaching and learning. We present language-learning contexts from across formal and informal language learning in English for Academic Purposes (EAP). Our experience relates to Open Educational Resource (OER) options and Practices (OEP) which are available for developing and distributing online subject-specific language materials for uses in academic and professional settings. We are particularly concerned with closing the gap in language teacher training where competencies in materials development are still dominated by print-based proprietary course book publications. We are also concerned with the growing gap in language teaching practitioner competencies for understanding important issues of copyright and licencing that are changing rapidly in the context of digital and web literacy developments. These key issues are being largely ignored in the informal language teaching practitioner discussions and in the formal research into teaching and materials development practices
