It s a perfectly valid (if archaic) English verb, methinks. Using it overly would be considered an affectation but if the teacher is under the impression that it is grammatically incorrect then, sadly, she isn't at all well read.
Personally, I would have the 'communication' conversation as outlined by Aeh as it is broadly applicable not just to conversation but all forms of expression even Art.
Also, I myself wouldn't encourage my child in riling the teacher or proving them wrong - nobody likes a smart Alec and unnecessarily souring the relationship with the teacher is not something that I would encourage, frankly. Learning to appreciate and respect the likes and mores of the 'receiver' of one's outputs is a valuable Life Skill, methinks.
YMMV
