A petri nets-based approach to modeling SCORM sequence

In order to adapt the teaching in accordance to individual students abilities in the distance learning environment, more research emphasis on constructing personali ed courseware. The new version of SCORM 1.3 attempts to add the sequence concept into this course standard. The sequencing 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 net to decrease the complexity of the sequencing definition model in the SCORM 1.3 specification and construct framework within various instructional strategies by piecing subnets together.
