Achieving learning object interoperability and reusability through object orientation

Throughout the literature there is significant evidence to show that in general the goals of learning object reusability 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 orientation such as inheritance, polymorphism, information hiding and instantiation among others play a significant role in interoperability and reusability in a theory of learning objects presented in a previous paper.
