The book's premise is research that directly involves the subjects--children! As pointed out several times by the authors, not enough research is carried out observing children while in an unobstructed "play" setting. Kids know not to answer interviewers certain ways and they are experts at adjusting their behavior when they feel that adults are watching. The authors also break down why teachers enforcing tolerance and celebrating diversity isn't enough of an effort to handle race in the classroom and provide additional information about how teachers can make more of an effort. But, most importantly, the authors emphasize that children do not only learn how to engage with race from the immediate adults in their life. Children as young as three are sophisticated and observant enough to understand race as it operates in the larger society around them. There are millions of cues that guide their ideas-- who they see working what jobs when they are out running errands with parents, television shows, movies, etc. Children have to be held accountable for the inappropriate ways that they may use their knowledge of race, which can only happen once adults stop treating children as mere naive receptacles and instead active and competent participants in the social world. They are not color blind nor incapable of understanding race, as proven by the research discussed throughout the book. Play time is more than cute and fun, it is complex and requires practiced social skills, and this makes the time a rich resource to learn more about children and how they process and express their understandings about society. When a child makes an inappropriate comment, for example uses a racial epithet, it can't be dismissed as inconsequential. That child, even if they are three years old, probably DOES know better. Adults cannot become defensive and argue that the child didn't learn that from neither here nor there. The blame falls on the society as a whole which operates according to strict racial lines at all levels of society.
