I had a similar lesson, except that we had to make the change to our own
program (ground rule 2 applied in our case).  I found this to be one of
the most powerful lessons I got in school.

Another way to implement your technique would be to give all the students
the same working program and have them modify it.  Stage one: give them
a "good" program to work with.  Stage two: give them a horrible one;
ideally
one that has already been badly maintained by a different programmer than
the original.
