The Status Quo of public school policies in the USA is generally what Creationists prefer.It mostly protects Christianity or Creationism from being bashed (or even coming up)by non-Christian teachers.The way Evolution is presently taught, in (U.S.of)American public schools, almost gurantees that students wont ever think of it having anything to do with the issue of the Bible.It is sort of a wall of protection for students from non-Christian(and non-Jew,etc.)teachers.
I agree with that.
But then,if the teacher is a Creationist, then the teacher can discuss the Science text book's material however he or she wants to.
But there, I disagree.
Sure, the creationist teacher can state that he/she is a creationist, and doesn't personally accept ToE. But he cannot actively teach that evolution is wrong. There is a curriculum, and the teacher is expected to teach that curriculum. If his own beliefs prevent him/her from teaching the curriculum, he should insist that he not be assigned to teach the class that deals with evolution.
Note: the "can" and "cannot" above are not comments on legality (which would mostly be case law). Rather, they are comments on what I would consider ethical for a teacher.
