In the United States children are taught, starting in kindergarten, what is considered appropriate behavior. They are expected to learn and say the Pledge of Allegiance every morning. When their teacher wants to get their attention, he or she may ring a bell or turn the lights on and off rapidly. At this time, students learn very quickly to stop whatever they are doing and to sit on the floor in front of the teacher. As they progress through school, teachers still have expectations of the behavior they would like to see in their students. What is operating in American schools?

Hidden curriculum in sociology is defined as a side effect of schooling, something that is learned that is not intended to be learned but it end up being learned, like norms, values, and procedures, for example, in this case when they learn to say the Pledge of Alliance every morning the are unintentionally imposing values to the kids, also the stimuli given by the bell or the lights as a way of getting the kid's attention.
