High-level Authoring of Simple Sequencing Descriptions

Simple Sequencing is a specification for describing educational activities dynamically presented to learners based upon the achievement of specific goals during their navigation in educational content. Authoring such descriptions is a difficult task. This paper describes an approach for authoring Simple Sequencing descriptions by hiding underlying details. This approach is based on a mapping between Simple Sequencing descriptions and statechart diagrams, a well-known formalism for describing hypermedia. Based on this mapping, an authoring tool has been developed, which is also presented.
