Wrong quiz scores in Moodle
One of our trainers noticed that the score on the Storyline Results Slide is often recorded incorrectly in Moodle’s Gradebook. The wrong grades were always lower than what the learner earned, sometimes a zero. (Fortunately, the quiz results have no effect on workers' performance appraisals.)
Exporting the Moodle Interactions Report revealed that, when a learner reaches some seemingly random question, the system stops reporting to Moodle and reports none of the responses afterward. The spreadsheet cells for these responses contain “ ”. The Storyline SCORM package continues as normal when this happens, with the correct grade appearing in the Results Slide.
For one quiz 14% were recorded incorrectly. Another quiz, had 10% that were wrong.
I have spent many hours analyzing the problem. I haven’t been able to identify any common factor that connects the learners who have incorrect scores. I attached some data. Here are the relevant settings (I think):
Storyline Publish Settings:
- SCORM 1.2
- Report status to LMS as: Passed/Incomplete
- Track using quiz result
- Result slide to report: 1.15 Results Slide
Moodle SCORM Compatibility Settings (Version 2.7.7)
- Force completed: Yes
- Auto-continue: No
Moodle SCORM Attempts Management Settings
- Number of attempts: Unlimited attempts (Note: Once Moodle stops recording grades, subsequent attempts are not recorded)
- Attempts grading: Highest attempt
- Force new attempts: No
- Lock after final attempt:
I am completely stuck. Any suggestions will be welcome. Moodlers, I encourage you to check an Interactions Report and see if you have a similar problem.
