Your help is much appreciated concerning online distance quizzes. We're facing some issues with certain students stating that they've answered the questions of a quiz but Moodle didn't save their answers. Their attempts are either empty or half-empty.
Placing every question on one page, consulting the logs, tele-surveilling students are not sufficient to give us a physical proof that a student actually answered the quiz's questions but moodle didn't save them and this is causing a big issue here. Let's not forget that we made sure that the student didn't have any technical and/or connection problem,
Do you have any suggestion that can be used as a physical proof for this situation ?
