An online student emailed me this week. He'd forgotten to do two papers; was there any way I'd accept them late?
The papers were due in February and March.
The truly bizarre part is that he's been doing the weekly assignments. Which means logging on and scrolling past 'Dropbox for Paper 2' to get to 'Weekly Assignment #X'. Wouldn't you think that seeing 'Paper 2 Due Feb. X' would prompt one to wonder, 'What is this Paper 2 of which you speak?'
Plus, the gradebook is available 24/7. That he has never had in excess of 50% in the class, apparently has not worried him until 75% of the semester has passed...
