Work in progress - new data structure in SCORM 2004 sequencing & navigation

SCORM is one of the most important specifications in e-learning. Its content aggregation model and run-time environment has been implemented in a large number of learning management systems (LMS). SCORM 2004 has defined a Sequencing specification which facilitates the instructional design of a subject. Faculty can define what contents should be studied and what questions should have been answered correctly before the study of a new content.But this sequencing specification presents some limitations, as the processing speed, which could be slow if the number of students is large, and the reading of the results, which is difficult if the teacher has not any SCORM knowledge. In this paper, a new open source tool, with a new organization of the data which minimizes the calls between modules is presented, increasing the processing speed. In addition, the results reports are shown in an easy way, in order any teacher can use them without any previous knowledge. These improvements do not affect the compatibility with SCORM 2004 content packages build over other systems.
