While the UK has effectively banned the teaching of creationism in sciences courses through an application of incentives, the US is going the other direction. Recently, Indiana's Senate Panel just OK'd the teaching of creationism in science courses. It's not completely confirmed yet, it still needs to be ratified by the full State Senate, but this is a step in the incorrect direction.
I'm not saying this because of any religious beliefs on my side, which I'm against creationism as a whole, but because it will have a massive impact on any scientific future for these students. None of these students will have the proper understanding of biology to be a doctor, biologist, virologist, biomedical engineer and the list goes on. These are just professions that they are being directly impacted on. The secondary professions will be most of science and engineering professions.
Why? Well as Neil de Grasse Tyson argues, the moment you start saying God did it, you're useless in the lab. Not because you can't research or you're religious, but because that means you've lost the burning desire to know "why?" A researcher needs to have a desire to explain what has been unexplained. To investigate the how and what of making things work.
This can also have a chilling effect on entrance into science based universities. Essentially, these students, to the universities point of view, would have had no biology what so ever and the rest of their scientific education may be suspect as well. If creationism is allowed in biology, what sort of impact could this have on their physics and chemistry courses?
Will this ultimately pass in the larger Senate? I honestly don't know. Should it pass, I hope that there will be an injunction before this is instituted and a case to determine the constitutionality of this law. While the law is likely written to be rather aspecific on what religions it is not supposed to be from, it is obvious to most observers that this is based on Christianity. Essentially, this would be a state endorsing a religion. Thus many people could object to this including Muslims, Christians that don't support the Young Earth Creationist view, Hindus, and of course atheists.
Now, if you want to send your kid to a private school to learn about creationism then go ahead. That's why there are options. But I know if I ever have children, they are not going to be educated in a public school system that allows creationism to be taught next to evolution.
