摘要:This paper looks at how the concept of reusability has gained currency in
e-learning. Initial attention was focused on reuse of content, but recently
attention has focused on reusable software tools and reusable activity
structures. The former has led to the proposal of service-oriented
architectures, and the latter has seen the development of the Learning Design
specification. The authors suggest that there is a mutual dependency between
the success of these two approaches, as complex Learning Designs require
the ability to call on a range of tools, while remaining technology neutral.
The paper describes a project at the UK Open University, SLeD, which
sought to develop a Learning Design player that would utilise the
service-oriented approach. This acted both as a means of exploring some of
the issues implicit within both approaches and also provided a practical tool.
The SLeD system was successfully implemented in a different university,
Liverpool Hope, demonstrating some of the principles of reuse.
