The law specifically states that:
So they aren't just going to sit in class while the teacher makes a presentation on evolution. I just hope the law doesn't have a chilling effect on the way science is presented because of the requirements of this law. The teachers will have to find a place for those students to go, and they will have to make separate tests and homework for those students whenever any topic conflicts with a particular students beliefs (And probably more important the parents beliefs). Any subject could be impacted by this law.
In a basic nutshell, this law allows students to be completely isolated from knowledge of various topics and subjects. Obviously, I suspect science will be the most impacted.
The only thing stopping them would be their parents. I would imagine that this will be done in a teacher-parent conference and the student may or may not be present.
I'm sorry about the confusion here. These comments are directed towards the changes in law of Louisiana. I regret not making a separate thread because its caused some confusion in this one.
