Prevent editing of videos after submission to Moodle assignment
I've been testing the Atto editor method for submitting assignments in Moodle however there's an issue for us in that students can still edit their work after it has been submitted, which could potentially lead to academic misconduct.
It would be ideal if once the student has submitted they no longer have editing rights for the video(s) they have submitted, regardless of whether it's in a personal or assessment folder in case they upload it to the wrong place.
I believe there are two ways a submission could be classed as submitted, depending on the Moodle assignment settings. Either the due (or late) date passes where the student is not asked to click a submit button, or (and this is the method we use) the student clicks a submit button. Beyond that point the student should not be able edit the video(s) they have submitted.
Closing the assessment folder is one option but not really robust enough as students submit at different times and some are given extensions. It would also mean a new folder needs to be created which the tutor could forgot to do.
