    Abstract
    The knowledge represented in learning materials for the sciences is typically organized around term-based or "weakly-structured" models of concepts and their interrelationships. We introduce a "strongly-structured" model of scientific concepts that provides the foundation for a knowledge base (KB) of concept representations. An extension of the Alexandria Digital Library employs such a KB, together with associated collection and services, to support undergraduate leaming.

    Abstract
    Describes the use of concept maps as one of the semantic tools employed in the ADEPT (Alexandria Digital Earth Prototype) Digital Learning Environment (DLE) for teaching undergraduate classes. The graphic representation of the conceptualizations is derived from the knowledge in stronglystructured models (SSMs) of concepts represented in one or more knowledge bases. Such knowledge bases function as a source of "reference" information about concepts in a given context, including information about their scientific representation, scientific semantics, manipulation, and interrelationships to other concepts.
