Model-driven development of learning objects

The development of effective learning objects that explores blended learning, collaborative, and open development requires a laborious process. Information created and used at each phase of the process must be manually translated and augmented until achieving a proper product. The issue of systematic development of learning objects can be addressed using model-driven development. In fact, each phase in the development of learning objects requires a specific type of user/developer profile and generates different models. This article defines a model-driven approach for the open and collaborative development of learning objects. The approach herein described uses concept maps, represented as CXL documents, and statechart-based models, which are represented as UML models in XMI documents. Finally, the later model is used to generate learning objects, given a specific platform description. The current implementation supports the generation of slides in LaTeX/Beamer format. The feasibility of the approach is demonstrated using a course on software testing for undergraduate students, with learning objects generated for a context that comprises both traditional classroom and blended learning.
