I think it's only wrong in the sense that lower levels of education are biased towards a kind of rote memorisation of bashing everyone into performing the same basic task in the same way to get the same results which look good on the test. That is certainly something which is more likely to have a negative effect on an artist's potential than anything else (but the same is true of any other subject IMO). Actual careful study which involves acturally engaging with the subject will generally enhance anyone's capability in the subject, even if in art usually you succeed by breaking 'the rules' in some way or another.
