Interestingly virtually all the opponents of Creches are also opposed to Menorahs, however a judge in the late 80s determined that Menorahs have no connection to Chanukah and the Jewish faith, but are secular objects like Santa Claus. Personally, I find the judges decision offensive, in addition to being factually incorrect.
I can't imagine what they'd want to teach, but you can rest assured that religion has no part of it. Personally, I'd cancel all the "history" months, other than an American history month, which we could desparately use.
