Granularity | 01/03/2003

"Granularisation" is a clumsy word for an elegant concept. It refers to the size of learning objects. Granularisation is a necessary condition for learning objects to be shared and reused. Reuse is necessary to gain economic benefits from educational technology. Economic issues cannot be ignored. It may be possible for a single, well-funded project to produce superb, interactive, absorbing online learning material but the wide-spread use of such high-quality resources cannot depend on project funding. It must depend on a form of " learning object economy" in which trading (sharing) occurs so that each contributor has access to a much larger pool of resources than they can use and reuse. The effort and cost of production is then balanced by the benefit to a large number of implementers.
