You may remember the paper on teaching the definite and indefinite articles and a
crosslinguistic rule that I researched to make the correct use of English definite and
indefinite articles easy for Chinese students. That rule is based on Contrastive
Grammar, an it is an example of some of the rare cases where Contrastibe Analysis could
be useful

Nobody thought it was useful.

Just regurgitating the obvious in overly obtuse terminology.
