They probably can't tell the difference.
Most pupil work consists primarily of material copied from books and encyclopedias.
That being the case, it might make sense to assume that teachers would pay particular
attention to what's being copied. In actual fact, however, this only rarely happens.
Dress it up with nice graphics and clean layout and nobody is going to pay much
attention to the content.
I doubt that most teachers would pay particular attention to the particular content
that a pupil quotes. Quoting from what sounds like a reliable source is probably
sufficient for them. What's more, I wouldn't count on teachers knowing that there's
something special about the Wikipedia outside of the fact that it's free. But
come to think of it, I sort of doubt that many pupils are going to making very
frequent use of it as a source - so far it contains very few graphics.
