I hope you'll check out Easy to Love, Difficult to Discipline. It's an amazing book!!
I did great in terms of classroom management at my school. My point was that children who are in "survival mode" do indeed exhibit different behaviors than their middle-class counterparts. I'm not saying the behaviors can't be extinguished eventually with a great teacher who is able to build a sense of community in the classroom.
I was talking about the Culture of Poverty--the fact that children living in poverty have very different lives than other children, and these differences result in different needs. I'm not saying we should have low expectations, but we should be honest about what kinds of problems these children are dealing with in their daily lives.
School segregation is alive and well in many parts of the country with the "haves" and the "have-nots" being separated just as they've always been...Behavior issues are magnified when these children are separated from their middle-class pears. In the Culture of Poverty, children learn not to back down because it will show that they are weak. Compliance is a sign of weakness rather than a strength.
What I'm saying is that these children are living in a very different world which can result in difficulties in school--not to mention that behavior problems often arise when a child's academic needs aren't being met (as is the case with many of these children).
I recommend any of Alfie Kohn's books for teachers OR parents who are interested in a new way of thinking about children and discipline.
And How to Talk So Kids Will Listen and Listen So Kids Will Talk is a well-written, easy to understand *quick* read that I recommend often..
About smacking, I have a 5 year old and a 2 year old who are both strong willed but have never been struck for any behavior. There are other alternatives but it's easier to hit than to redirect.
