A GeoGebra applet as SCORM package, running in LMS (Moodle)!

Sharable Content Object Reference Model (SCORM) is a collection of standards and specifications for web-based electronic educational technology (also called e-learning). It defines communications between client side content and a host system (called "the run-time environment"), which is commonly supported by a learning management system. SCORM also defines how content may be packaged into a transferable ZIP file called "Package Interchange Format." [Text from Wikipedia]

Applet variables

In order to compute some values, some information from the GeoGebra applet is needed. Therefore there are a couple of variables that can be defined in the applet:

  • SCORMCompleted (bool) for cmi.completion_status
  • SCORMSuccessful (bool) for cmi.success_status
  • SCORMMinScore, SCORMMaxScore, SCORMRawScore (all float) for cmi.score and cmi.success_status

SCORM Data Model

SCORM variable Value(s) GeoGebra Applet variables
cmi.completion_status
  • "unknown" if SCORMCompleted is undefined
  • "completed” if SCORMCompleted is true
  • “incomplete” if SCORMCompleted is false
SCORMCompleted
cmi.exit
"normal"
cmi.score
If the variables SCORMMinScore, SCORMMaxScore and SCORMRawScore are defined in the GeoGebra applet:
  • cmi.score.raw = SCORMRawScore
  • cmi.score.min = SCORMMinScore
  • cmi.score.max = SCORMMaxScore
  • cmi.score.scaled = (score.raw - score.min) / (score.max - score.min)
SCORMMinScore
SCORMMaxScore
SCORMRawScore
cmi.session_time
Sends the elapsed time between opening the applet and clicking the button.
cmi.success_status
If cmi.scaled_passing_score is defined (and cmi.score was computed):
  • “passed” if cmi.score.scaled ≥ </code>cmi.scaled_passing_score</code>
  • “failed” otherwise

Otherwise have a look at SCORMSuccessful and return:

  • “unknown” if SCORMSuccessful is undefined
  • “passed” if SCORMSuccessful is true
  • “failed” if SCORMSuccessful is false
SCORMMinScore
SCORMMaxScore
SCORMRawScore
SCORMSuccessful
