摘要：Gord McCalla's paper describes the development of a user-centred system that links and accrues individual learners' profiles, usage and ratings data to learning objects. This allows algorithms to identify and recommend those learning objects that are best tailored to a learner's purpose and learning style. He uses the concept of the "ecological web" as a metaphor for the evolutionary journey (birth, growth and death) of online learning objects from the moment that they are added, through their useful life as a resource, to their deletion once obsolete.
