I am teaching a class with roughly 50 students in it. They have
quizzes and homework each week, and I end up alphabetizing these
papers before I return them to the students. Some of you may be in
similar situations. My question: what technique should I use to sort
the papers? (Or maybe: what techniques do you use to sort papers in
situations like this?) ....
Being utterly untrained in computer science, I've devised my own
"square root" algorithm for exactly this job.
The square root of 50 is roughly 7, so lay the scripts on the
floor in 7 columns of about 7, spreading the columns vertically so that
you can see the name at the top of each script. Next order the first
column's scripts alphabetically in your head (which isn't hard for just
7 of them), and rearrange that column with A at the front (bottom) and Z
at the back (top). Repeat for the 2nd, ..., 7th columns. After that
you need only look at the front (bottom) script in each column as you
pick them up in alphabetical order.
It's easier to do than to describe. The reason for choosing the
square root is just to equalize the number of names to be perused at
each stage.
Very possibly this sorting method is well known and has a standard
name, but I invented/discovered it independently. ;-)
