Problem when student resumes his attempt
Oct 27, 2020
We have developed many learning packages with SL360, and we have uploaded them in a Moodle 3.9. The export of these packages has been in the SCORM 1.2 standard.
We are having problems with user attempts. Specifically, when they try to retrieve the information saved from their attempt. The most common problems are:
- When the students relaunches the package, the window freezes or blocks and they cannot navigate.
- Sometimes, the student does not see all the content of the activity: phrases, images, texts are missing, etc.
The only way to fix these issues is to remove the attempt of that student, losing their progress, and have to redo it all from scratch.
I've tested these packages on cloud.scorm.com as well, and they still reproduce the same errors, so I think it's a problem with building the packages (.story proper) or exporting to the SCORM 1.2 standard. Also, I think that the problem has to do with the decoding of the cmi.suspend_data field, but I don't think it is a problem with that field, since it is of type LONGTEXT in the database, with space up to 4 gigabytes.
For example, on the next screen, the student correctly retrieves the last activity visited:
But when the student navigates, on the second or third click, the SCORM freezes:
I have also attached a log file, with the activity logs for this example, including the moment the image freezes, and apparently, there are no errors.
I really appreciate any help you can provide.
