Creating courses by combining Learning Objects (LOs) sourced from third parties, known as courseware, is becoming more popular of late. Although courseware has advantages over traditional courses, it can be difficult to ensure a consistent instructional approach and strategy that satisfies the original courseware construction concerns, due to the abstracted view of LOs the course creator now has. Courseware validation, validates a constructed course against a validation model which specifies correct and incorrect course behaviour. Our approach to courseware validation allows the course creator to specify a validation model using a novel information architecture which captures the major course construction concerns. Validation can then take place within the context of this archtecture. This ensures the original concerns are realised in the constructed courseware.

www.uneb.br Abstract: This paper describes how the Astronomy case study is modelled, created and executed, using a IMS LD ontology. The ontology was aimed at overcoming the expressiveness limitations of the IMS LD XML Schema by means of a taxonomy of concepts and a set of formally defined axioms. With regard to the authoring (creation) stage, the ontology has been used to enable the automatic validation of IMS LD documents in WebLD, a web authoring tool to create IMS LD Units of Learning. With regard to the execution stage, a service-oriented architecture was developed to allow the execution of IMS LD Units of Learning, whose learning processes have been modelled through Petri Nets.
