Perhaps you can leave the course open for a while longer, and override the due dates for this particular student's specific quizzes and assignments. Other students will see the course open but won't be able to do assignments.
I have experienced all kinds of excuses.
Yes, all kinds of deaths of family members. I am attaching an article about this.
Yes, all those COVID excuses.
Yes, the single student who was totally attached to her dog, then her dog died.
Yes, the student whose best friend died. Or a friend of a friend.
Yes, the student whose parent died at the beginning of the course, affecting them at the course's end.
Yes, the student whose car battery died on the way home to take the online exam.
Yes, the student whose computer died right before taking the exam.
Can you tell me that one of these deaths is less significant to the student than the other?
My proposal has been for the university to give an exception to the student, allowing them to retake the course for free. However, whenever a suggestion involves the university making time or cost concessions, the university seems unwilling to put in the extra effort. Hmmm, the university is willing to change their rules??? Still, the university has no problem having the instructor do so.
My daughter told me her story. She was taking a course with firm due dates. She was a single mom, with a two-year-old child. To meet the due date, she had to hire a babysitter. Then, the day the assignment was due, some students didn't finish their assignment on time, and the instructor said, "I'll give everyone five more days." Was this fair to my daughter, who paid for a babysitter to complete her work?
I maintain that having a firm due date is the only fair solution.
In this attached article, I have always enjoyed the author's three solutions. Enjoy.
