Scalable, multidisciplinary learning objects: technology and pedagogy

Learning requires a dialogue between abstract knowledge, such as theory, and application in specific contexts. A learning object (LO) for learning about network technology, scalable for level of complexity, and usable for abstractions in both business and engineering contexts, was developed through the application of two principles: separation of application from abstraction, and instructor-guided abstraction. The LO, design principles, and design and evaluation strategies, are described in this paper.
