If teachers would really want students not to cheat, they wouldn't allow graphing calculators.

That's the point : teachers know at least several students will disobey. They know people can enter formulas in it.If an instructor allows students to store formulas in their calculator then they may do so, but if it is disallowed, then that rule is independent of the authorization to use the calculator itself, even if the instructor expects that students will probably disobey.

Well, I thought that was what the original poster wanted to ask about...You sound as if the only purpose of a graphing calculator is to store formulas.

They can provide the graph in the paper test...There are plenty of other legitimate reasons why one would want to use a graphing calculator on an exam. Perhaps an instructor wants to have students solve some problems graphically,

Two possibilities :

- in high school, the student will be asked to sketch the graph in a test..

- in University, the "sketch the graph and find solutions thanks to the graph" part is not significant. I don't even think they'd be asked such a thing... In general case I mean.

That's partly where there may be a difference between our countries. In France, we have scientific calculator before having a graphing calculator.or maybe he or she feels it inappropriate to require students to spend $10 on a new scientific calculator when the graphing calculator they already own has all of the necessary capabilities.

Allowing it, knowing that it's possible to "cheat", means that they can, unless the teacher explicitly states that it's forbidden. Even with that recommendation, he won't be able to check everybody "are you typing the calculus or typing to retrieve your text with formulas ?".Allowing the students to use the device does not imply that they accept cheating with it.

That does imply that he doesn't forbid it...While this changes your meaning somewhat, I still say that a teacher knowing about a possible avenue of cheating and not preventing it does not imply that they allow such cheating.

They don't forbid it either, although they know about the misuses.Yes, I'm sure that most teachers probably know what students can do with a graphing calculator, but that does not mean that they automatically accept or allow misuse.

When did he say "I forbid you to store formulas" ? He knows they can, but no rule says that they ought not store formulas.But when did the teacher say "Iallowyou to store formulas or notes in the calculator"?

While you referenced to burglar or assassination, I see a huge difference : we're given the possibility, but the laws forbid it. There is a rule which has been set up, and that makes the difference...

- the use of graphing calculator.What difference does one's country make? Certainly, different cultures, communities, and even individuals will tend to carry different moral views, but if you are trying to argue over whether something is right or wrong, your country of origin is usually irrelevant.

- the habit of teachers to write up paper tests, following their directives about graphing calculators using or not.

Other things I'm questionning but it can look stupid. As I said, it "MAY" be different

Here, we were always told that if graphing calculators were allowed, they wouldn't put high marks in questions needing to know formulas.That is, unless you were referring to the actual tendency of students to use graphing calculators for storing formulas, and teachers' knowledge that it is commonplace, in which case I would say that the US is probably not much different from France or most other locations.

"Shouldn't", I agree, but how would you stem this "commonplace" thing ?I wasn't arguing that this sort of thingdoesn'thappen, only that itshouldn'thappen.
