Assembling content into dynamic learning objects versus authoring of e-learning courses.

Abstract

It is our goal to assemble the content into dynamic learning objects (LO), to make the content adaptable to the learners prefernces and to all kinds of used appliances by the learner. A three layer e-learning course development model has been defined based on the “conceptual model of content object”. It starts by decomposing the learning content into small chunks which are initially placed in a hierarchic structure of units and blocks. The raw content components, being the atomic learning objects (ALO), were linked to the blocks and are structured in the database. We set forward a dynamic generation of LO's customised to the learner group on point of content and customised on point of presentation, fitting the preferences and the used appliances of the learner. In that view we need a LO assembling system fitting the requirements of interoperability and reusability and starting from selecting the raw learning content from the learning materials content database. The company AGFA Healthcare is using an authoring system that creates SCO’s being interoperable. Thanks to a good management is the solution a best practice, even it is not based on a database. Though they can not create dynamic solutions and cannot customise the e-learning module on the fly to the learners preference and the used appliance by the learner.
