Tracking by using number of slides viewed
I want to make sure that a student saw all slides of my course. So I go to publish --> LMS --> Tracking and choose "Track using number of slides viewed" and the minimum number 5 of 24 slides. I do the same setting for Reporting and tracking. When I add the course in Moodle it does not track the progress of the student. What do I wrong? When I put a quiz into the course I can track by using the quiz result..
(The minimum number of viewed slides "5 of 24" was just to test. Actually I want to use "24 of 24" but this does not work either..)
I would like to track not just 0% and 100% but the current progress the student has (25%, 60%,..).
Thank you very much in advance!
