Tracking the number of slides on LMS

SCORM doesn't have a data element for "slides viewed". Using the SCORM data model, one of the ways you could do this is using a score %. You'd need to use some custom JavaScript and additional triggers to get this done. 

Off the top of my head:

• Create a set of variables to hold your "slides viewed" tally, the current slide value, and the total number of slides. masteryArray, cSlide, and tSlides in the example below.
• Create a trigger on each slide to change a current slide variable (ex, cSlide) to the number of the current slide (1, 2, 3, 4, 5, 6)
• Create a trigger on your master slide to execute a JavaScript trigger whenever cSlide changes.
• In this trigger, grab the value of cSlide and change an array index to 1 when that slide is visited. Converted to a string, for example if masteryArray was 0,1,1,1,0,1 then slides 1, 2, 3, and 5 would be visited. (the first slot is always going to be 0 in this example since the index address is 0)
• Also in this trigger, calculate the sum of the array. In the example above, the total would be 4. 
• Also in this trigger, run the calculation for the total number completed by grabbing the sum and dividing by the value of tSlides. If the total number of slides was 12, the completion would be 25%. 
• Use the LMS API to submit the score to the LMS. 

So when all is said and done, the LMS will get a score report every time a new slide is visited. Some LMS may not like this as they could close off additional reporting once the score has been set.
