Nice article by Cisco's Chuck Barritt that applies Ruth Colvin Clark's four archtectures to the deployment of learning objects in learning object management systems. Most of the article is review, but Barritt is able to nail down one of the weaknesses in contemporary learning objet technology: "What is missing is the use of those LOs in all four architectures, especially Guided Discovery. The challenge the human performance technologist is to design applications and interfaces to leverage those existing LOs as Guided Discovery architectures."
