This is just as I expected and wrote in earlier posts. It appears that the State Board didn't know what kind of curriculum would be appropriate to put into place, and figured that if it did so, they would face litigation. Well, they are going to face litigation no matter what they do, but to give no guidelines is asking for major trouble. How many education majors ever take a religious studies course? How many have any idea how to teach a religious studies curriculum? How many even are aware that there is a difference between teaching about religion and teaching religion?
But even this difference won't matter because there are going to be lawsuits no matter what kind of course is run. Consider the parents who will take the school to court if the teacher were to teach about religion? What will happen when the students begin to learn that the historical, literary, and social history of the Bible is not what they have been taught in church? The parents will scream that their children are being taught against their religion, and will sue or kick out the teacher just as we saw in the Friendswood incident. If the teacher teaches religion, that is proselytises and turns the class into a prayer bible study, then other parents will sue that the separation of church and state has been infringed upon.
What a mess!
