In my service learning classroom, I've noticed that more times than not, the teacher takes the answers of girls before the boys. They are also lined up in passing time with boys in one line and girls in another. I still wonder as to why.
The boys have the greatest likely hood just to throw out an answer and hope its right. The girls sit and wait with their hands up for the teacher to call on them. This teaches them that they have to be patient and that the boys can do whatever they want. Again like Kozol, gender plays a huge role in our society so separating the genders even at the young age in kindergaten teaches them right off the bat that girls and boys are different and that the girls will wait and boys can do whatever and they still will not be punished.
