SL360 - Deployed module doesn't fully progress for some learners at random.
Sep 01, 2022
I have an issue below which i'm hoping someone out there has come across before and could provide some assistance / insight on. :)
I have a frequent issue with eLearning modules developed in Storyline 360 (which spans across multiple modules). It appears at random the deployed module will stop progressing for some learners. For example, if a module contains 30 sequential slides each with a NEXT button to move on from slide to slide, somewhere within those 30 slides the module will just stop progressing. Sometimes the learner will get to a random slide such as 20/30 or 25/30 sometimes 4/30 at this point the next button will do nothing. This sometimes can be a frequent event, frequent enough to cause concern and problems further on down the line.
I’m asking if you could provide any insight as to why this is happening?
Does storyline stream a module via LMS to a learner?
Is it possible the stream is interrupted?
Perhaps the module is downloaded in bulk at the start and the download doesn’t complete? (maybe due to network issues).
Maybe content heavy (large source file) modules are prone to error?
At the moment the only solution to this problem Is to get the learner to delete their browser cookies/history and restart the module from the beginning. This often then allows the entire module to progress as expected. (re-downloads the module?).
Maybe these issues are caused by poor network connections? If that’s the case is there anything that can be done to reconnect these modules without needing to delete cookies.
I would also like to know more on how a storyline module is sent to and from the learner?
Does the module send a kind of heartbeat to an LMS to keep connection?
I’m at a loss as to how I can investigate this issue at the moment, any help or guidance would be gold.
Thank you very much for your time.
