The concept of a learning object (LO) has spread quickly without a very specific universal definition, and though born originally from the idea of object oriented design, with a goal of providing high levels of reusability for digital learning resources, it is being developed generally without reference to the ideals of the object oriented design paradigm.(More)
Throughout the literature there is significant evidence to show that in general the goals of learning object reusabil-ity and interoperability are not being met very well. In this paper we discuss how object orientation can be applied to the learning object concept to improve interoperability and reusability. In particular we show how features of object(More)
We present the view that for systematic software reuse (SSR) to happen we need a reuse software architecture (RSA) as the invariant base and a collection of reuse software components (RSCs) as the pluggable variant part of a family of architecturally similar software systems. We shall identify a reuse situation with a RSA, RSCs and a plugging operator. SSR(More)
