Take this anecdote for what it's worth, but my daughter has been home schooled or attended home school co-ops ever since Kindergarten (Ironically the reason we began to home school her was because of the principal of her elementary school - on the last day of kindergarten he gave a speech in which he pointed out that our children would spend much of their awake hours in the school and so it would be from the school that they would learn their values. I had never thought about it like that, but I clearly remember my years on public school and my wife and I agreed that we didn't want that for our daughter.) Anyway, Junior year of high school she decides that she wants to try public high school. That is fine with us so she starts attending in the fall. By the end of December she had decided to drop out. Here were her findings:
1. The students at public school are apathetic. The teachers were delighted with my daughter since she invariably knew the answers, would raise her hand, and would answer in full sentences. The other students would give as short of answers as possible and had to be prodded. This absolutely shocked her.
2. One day during morning announcements one of the guidance counselors said that she had handouts for some sort of career event coming up and to come by the office to pick one up. My daughter did so. Well it was a shocking experience for both her and the counselor. The counselor informed her that she hadn't actually printed out any of the handouts since in all the years she had been making similar announcements, not one student had ever stopped by to pick one up.
3. She learned that teen pregnancy is much more rampant that she had expected.
By the way, this wasn't some hick high school, but a large school in the suburbs of a large city. The students going here are mainly middle to upper class students.
A side note, even though she only attended one semester, when the year book came out she had more pictures (and even a half page article about her!) in it than any of her friends that attended the full year. She is very out going and vivacious and her fellow students and teachers really liked her, so it wasn't really a surprise. I was mainly surprised that I was so surprised at how apathetic the students are.
