Translating e-learning Flow-Oriented Activity Sequencing Descriptions into Rule-based Designs

In this paper, we describe how to automatically translate e-learning flow-oriented activity sequences into rule-based designs, such as those supported by the “de-facto ” e-learning modeling standard: the IMS Learning Design specification. Our aim is that instructors model their educational designs using a user-friendly visual notation. Then these designs can be automatically exported into standardized and interoperable representations, which can be interchanged with / deployed in a plethora of heterogeneous Learning Management Systems and tools. This approach has been implemented in e-LD, an authoring system which supports the authoring and refactoring of IMS Learning Designs using a floworiented visual syntax
