Is there anything INTRINSICALLY wrong with using
fields instead of variables ?
This looks like whether one wants to eat one's dinner
the British way (i.e. with an upside-down fork and cut
it up as you go along) or the North-American way (cut
everything up first and then eat it with the fork).
Admittedly using variable results in quicker programs
than using fields, but surely this is not a
shibboleth?
Teaching kids RR it is easier to use fields because
the kids can see them (i.e. they resemble the cups
with buttons in that I start with); most pre-teens are
not terribly hot with abstract ideas.
I would agree that what you teach should depend on where the learner is
on Piaget's scale of cognitive function.
But for adult learners, I usually teach fields for display and variables
for computation.
Variables play a central role in the art of programming. One could
argue that it would be a disservice not to explain how to use them well.
