IMS content package FAQ
From MoodleDocs
What is the difference between an IMS content package and a SCORM package?
The main difference is that IMS is mainly for "static" content - SCORM allows tracking of question/answers and reports a "grade" at the end.
If you want to do any tracking/grading then use SCORM - if you just want to display some content to the user - use IMS.
