Levels of reuse in educational information systems

A framework for reuse in educational information systems is elaborated, and evidence is presented that reuse occurs often at various levels of the educational enterprise. Case studies of the development of two online degree programs and one professional training program indicate that existing textbooks and government documents, virtual classroom tools, and administrative models and marketing mechanisms are reused. Effective reuse builds on models and mechanisms at the different levels of the educational enterprise – from individual learning to administration and from content development to delivery.
