Losing scorm completion data
We are getting lots of complaints from users who say they have completed our Storyline Scorm 1.2 activity (in both our Moodle 2.1 and Moodle 2.7 sites). The users even have screenshots of the completion slide, so we are certain that they did complete the scorm activity. But when they go back into the activity in Moodle or we export the gradebook results their activity completion is missing. If they go back into the scorm activity Moodle asks them if they want to resume. If they select Yes then they are redirected to the WRONG part of the scorm activity, somewhere in the middle of the activity instead of the end of the activity. They should be taken to the end of the activity considering that they have completed it. How can we troubleshoot and debug what is going on? Why does this happen in Scorm and Moodle?
We publish all our scorm activities in Moodle by linking to the scorm package's imsmanifest.xml file in the Moodle scorm activity in our courses.
The network connection in our office can sometimes get quite slow, affecting response times in Moodle. Could this have a bearing on the problem? Can a slow network connection prevent a scorm activity from writing back to the LMS on a regular basis?
