Having a three month old at home, I fully expect everybody else out there to get this title's play on the classic pregnancy book "What to Expect When You're Expecting" (that has made every expectant mother in the last twenty years worried sick). But, I'm…

ProblemWhen remediating after a retry sequencing request, you often want to skip sections that were previously satisfied or perhaps attempted. A common case might be a pretest that can only be attempted once or a SCO that doesn't have to be retaken if previously mastered.…

Curious about the adoption of SCORM 2004, I recently conducted an informal study of the packages uploaded to SCORM Test Track. Here's what I looked at and what I concluded. SCORM Versions I first looked at the distribution of SCORM versions over time. The data…

Retry All Resets Everything Many SCORM 2004 sequencing strategies require remediation upon failure. These strategies often call for only material which was not previously mastered to be required on subsequent attempts. The most straightforward approach to implementing such a strategy would call for storing mastered…

I recently completed development of a rather complex SCORM 2004 sequencing template for use by the Army in ATSC and TRADOC. It was working great in several environments, but imagine my surprise when it wouldn't pass validation against the XML schemas. A long investigation turned…

I just returned from the ADL Technical Working Group meeting where we tried to set forth a road map for the future of SCORM. With the stabilization of SCORM 2004 and the transition of SCORM stewardship to LETSI, there was lots to talk about and…

"Redundancies"....There's got to be a great quote from Office Space that should go here, but 30 seconds on Google didn't turn it up, so sorry, no snappy quip to start the morning.Because "Not Ain't Always Not" in SCORM 2004 sequencing and navigation, people tend to…

"It depends on what your definition of not isn't"Us programmer geeks have a very well defined preconceived notion of what "not" means. If I say: var person = Pick_A_Random_Person_Off_The_Street(); if ( NOT ( person.Thinks_Mike_Is_Cool() ) ) then print "mike is lame" else print "holy cow"…

SCORM 2004 Sequencing Tidbits #1: Post Condition Rules are a bit counter-intuitive on aggregationsSequencing post condition rules are only evaluated when an activity is "exited"....well, duh, right? Wrong. "Exited" is a particular term in SCORM 2004 sequencing and navigation. When the current activity ends, it…

SCORM 2004 provides a powerful language for controlling sequencing and navigation between SCOs. As with any deep specification, it can take a little getting used to. When you've been working with it for a while, you sometimes forget all those little stumbling blocks you overcame…
