Evaluation of Learning Objects
Reusability

ABSTRACT
Reusability of learning objects is evaluated on the basis of a priori software re-
usability analysis, which are related to cohesion and coupling aspects. A num-
ber of reusability metrics extracted from metadata records are dened and an-
alyzed to provide an aggregate reusability evaluation for learning objects in a
repository. e evaluation is validated and compared with an expert-based a
posteriori evaluation method.
Keywords: Learning objects, metadata, reusability.
