Abstract

Learning objects with high level of aggregation are very useful as a showcase of the possibilities of the different elements that composes them. The reusability of the whole high level learning object lays on the standard packaging technology is being used. But frequently, the teacher is only interested in a selection of the components or wishes to replace some elements by other ones.In this article, we present a proposal to deconstruct learning objects with high level of aggregation precedent from OpenCourseWare web sites and reuse selected components in different ways. Also, we present an implementation of this proposal as an example for the case of the OpenCourseWare educational resources.
