I'm trying to get a score, and progress from SCORM content (2004 Edition).So far I was able to save CMI values to my database using custom written LMS API.
cmi.score.raw--->>0
cmi.score.max--->>15
cmi.score.min--->>0
cmi.score.scaled--->>0
I need to know how to calculate the progress of the student, score and grade from above values. Is there a any specific way or function for calaluclate progress? Or am I missing some value from SCORM?
Generally you would not calculate the score, that is the value that you've shown--raw and scaled, and is set by the SCO. For progress, 2004 includes the cmi.progress_measure value though I think it is only used sporadically and again would be set by the content. There isn't really the concept of a "grade" in SCORM directly. There is the mastery score (or scaled passing score) that is intended to reflect the score required for the SCO to be considered passed. See https://support.scorm.com/hc/en-us/articles/206166246-Setting-the-mastery-score and https://support.scorm.com/hc/en-us/articles/206167026-What-are-the-elements-for-placing-a-passing-score-in-your-SCORM-manifest- for more about this value.
https://scorm.com/scorm-explained/technical-scorm/run-time/run-time-reference/ is a good reference for all of the runtime values.
