- 简介: For over a decade, the promises and challenges of learning objects have been attracting the attention of international research and development in technology enhanced learning. The notion of reusing and sharing resources for learning with digital media stimulated both technological advancements and pedagogical discussions. By means of modularisation and reusability, the quest for learning objects addresses the reduction of development and maintenance costs, the increase of quality, flexible learning and issues of accessibility for all. On the technical side, various aspects of information retrieval, architectures for distributed repositories, standardisation in e-learning and much more have been examined. On the pedagogical side, promises and challenges of learning objects fostered a highly inspired debate, ranging from educational ontologies, personalised learning and quality of media objects for learning to a worldwide movement of openly sharing resources for education. Especially the latter, better known under the label Open Educational Resources, leads to the insight that the notion of learning objects implies a transformation of educational institutions. Hence, focusing on learning objects fosters change not only on the course level, but encourages wide-ranging organisational reforms in the educational system.
