A friend of mine from Georgia (the US state) described his high school biology lecture on evolution as "OK, today I'm legally required to tech evolution. We all believe in Jesus, right? OK, next topic."
I went to a catholic elementary school, and one of my 6th grade teachers was a nun named Sister Catherine-Joseph who taught two subjects: religion and science. Despite the obvious setup for failure, she taught both rigorously, and well. I HATED that woman with a passion, but she was, absolutely, a superior educator who would have smacked the shit out of someone with a ruler for daring to suggest that, "We all believe in Jesus, *wink wink*" was either suitable coverage or a valid refutation of evolution.
