A Petri nets-based approach to modeling SCORM sequence

In order to adapt teaching in accordance with the abilities of individual students in the distance learning environment, more research emphasis is needed on constructing personalised courseware. The new version of SCORM 1.3 (scalable content object reference model) attempts to add the sequence concept into this course standard. The concept describes how the sequencing process is invoked, what occurs during the sequencing process and the potential outputs of the sequencing process. As a result, we apply the valuable features of Petri nets to decrease the complexity of the sequencing definition model in the SCORM 1.3 specification and construct a framework within various instructional strategies by piecing subnets together.
