Semantic web technology for web-based teaching and learning: A roadmap

The World-Wide Web has become the predominant platform for computer-aided instruction. Contentorientation, access and interactive features have made the Web a successful technology. The Web, however, is still evolving. We expect in particular Semantic Web technology to substantially impact Web-based teaching and learning. In this paper, we examine the potential of this technology and how we expect it to influence content representation and the work of the instructor and the learner

Designing learning object repositories : a thesis presented in partial fulfilment of the requirements for the degree of Master of Information Science in Information Sciences at Massey University

Learning object repositories are expanding rapidly into the role of independent educational systems that not only are a supplement to a traditional way of learning, but also allow users to search, exchange and re-use learning objects. The intention of this innovative technology is to have such repositories to collect a database of learning objects catalogued by the learning content management system. However, for users to perform an efficient search, these learning objects would need to use metadata standards or specifications to describe their properties. For learning objects stored within the repositories, metadata standards are often used to descibe them so users of the respositories are able to find the accurate resources they required, hence metadata standards are important elements of any learning object repository. In this paper, a courseware example is used to demonstrate how to define a set of characteristics that we want to describe for our courseware, and attempt to map the data schema in the database with the available metadata standards. The outcome is to identify a set of metadata elements that would fully describe our learning objects stored within the learning object repository, and these metadata elements will also assist instructors to create adaptable courseware that can be reused by different instructors. Metadata standard is known as a critical element for the management of learning objects, not only will it increase the accuracy of the search results, it will also provide more relevant and descriptive information about the learning objects to the searchers

A web services architecture for learning object discovery and assembly

Courseware systems are often based on an assembly of different components, addressing the different needs of storage and delivery functionality. The Learning Technology Standard Architecture LTSA provides a generic architectural framework for these systems. Recent developments in Web technology – e.g. the Web services framework – have greatly enhanced the flexible and interoperable implementation of courseware architectures. We argue that in order to make the Web services philosophy work, two enhancements to the LTSA approach are required. Firstly, a combination with metadata annotation is needed to support the discovery of educational Web services. Secondly, if these components are to be provided in form of services, more support is needed for their assembly. Architectural patterns of a finer degree of granularity shall satisfy this need

Ontology technology for the development and deployment of learning technology systems - a survey

The World-Wide Web is undergoing dramatic changes at the moment. The Semantic Web is an initiative to bring meaning to the Web. The Semantic Web is based on ontology technology – a knowledge representation framework – at its core. We illustrate the importance of this evolutionary development. We survey five scenarios demonstrating different forms of applications of ontology technologies in the development and deployment of learning technology systems. Ontology technologies are highly useful to organise, personalise, and publish learning content and to discover, generate, and compose learning objects

HTML Macros -- Easing the Construction and Maintenance of Web Texts

Authoring and maintaining large collections of Web texts is a cumbersome, error-prone and time-consuming business. Ongoing development of courseware for the High Performance Computing Consortium (HPCC) TLTP has only helped to emphasise these problems. Courseware requires the application of a coherent document layout (templates) for each page, and also the use of standard icons with a consistent functionality, in order to create a constant look and feel throughout the material. This provides the user with an environment where he or she can access new pages, and instantly recognise the format used, making the extraction of the information on the page much quicker, and less immediately confusing. This paper describes a system that was developed at UKC to provide a solution to the above problems via the introduction of HTML macros. These macros can be used to provide a standard document layout with a consistent look and feel, as well as tools to ease user navigation. The software is written in Perl, and achieves macro expansion and replacement using the Common Gateway Interface (CGI) and filtering the HTML source. Using macros in your HTML results in your document source code being shorter, more robust, and more powerful. Webs of documents can be built extremely fast and maintenance is made much simpler.

Open educational resources : conversations in cyberspace

172 p. : ill. ; 25 cm.Libro ElectrónicoEducation systems today face two major challenges: expanding the reach of education and improving its quality. Traditional solutions will not suffice, especially in the context of today's knowledge-intensive societies. The Open Educational Resources movement offers one solution for extending the reach of education and expanding learning opportunities. The goal of the movement is to equalize access to knowledge worldwide through openly and freely available online high-quality content. Over the course of two years, the international community came together in a series of online discussion forums to discuss the concept of Open Educational Resources and its potential. This publication makes the background papers and reports from those discussions available in print.--Publisher's description.A first forum : presenting the open educational resources (OER) movement.

Different Aspects of the Emerging OER Discipline

The more recent interpretation of open education is related to open education resources (OER), open education practice (OEP), and open access publishing. Although related to the original, distance education based interpretation, there is a distinct community around these areas. The inception of the OER movement, which can be dated as 2001, can be viewed as the basis for the open education movement. Although still relatively recent, this provides a sufficient timeframe for different sub- communities to develop with a range of priorities and interests. Based upon a content analysis of the OER Knowledge Cloud repository, this article examines the emerging sub-cultures within open education practice. Ten types of research article are identified that represent different approaches and issues for the groups involved
