I have been a modest Blackboard user. Discussion boards in upper-division classes and blogs for internships. In lower-division class, my Blackboard usage is dominated by textbook package of quizzes and other online activity. For the first time ever (and that's a long time), I have a student who claims to have submitted work that does not appear in the Grade Center. I have run Activity Reports and have also asked local Bb Administrator to review login activity. No indication that work has been submitted. Have also reached out to publisher tech support.
Does anyone have any experience with device or connectivity failure that might explain this?
