oh, that's what i really need. usually i failed to explain SCORM and elearning in plain words to novices. more than technical details, most teachers just need the direct benefits from SCORM module.

for me, the standard SCORM could be run properly across multiple platforms, and that's why i like to compile my contents to SCORM packages. such a standard is always a good idea to avoid any incompatibilities.
