I don't know, I think this could serve as a kind of innoculation if they taught the Bible story besides other culture's creation myths. Otherwise what happens is that (as all of us born-ins experienced) we are taught one set of things at home and then the teachers tell us another set of things, and where they conflict, we accept what our parents taught us.
I remember feeling like my elementary school science teacher was my enemy because she taught evolution. Maybe if they had acknowledged and discussed religious beliefs in school I wouldn't have felt like it was school/science vs. home/religion and would have been able to see how other religions had similar stories to the Bible.
However, one big problem is that the creation story, actually "stories", found in Genesis are not told accurately, but have been been touched up and modernized to accomodate our modern view of the universe. So if they teach the modern version of the story and compare it to stories from ancient cultures like Babylon which have not carried down to this day, those stories will look primitive and the Genesis account will seem more credible.
If the Genesis accounts were taught accurately, as I've discussed in places like this and this, it would not only be in line with the scholarship but it would give kids an alternate view of what their Christian parents were feeding them which would probably help them see how the Bible's primitive stories are subject to re-interpretation.
However I can't imagine Christian parents allowing this kind of education in school because it would seem like an attack on their faith. Teachers are going to have to just continue to encourage critical thinking without actually telling students what it is they need to be critical about.
