In the united states preschool teachers tend to believe that their job is to protect and support children's self-esteem. therefore it is unlikely that an american preschool teacher would ever criticize a student in front of others. these beliefs are conveyed through the

hidden curriculum.

Explanation:

Hidden curriculum  refers to unintended lessons or way of thinking that the students learn during the teaching process.

Hidden curriculum is usually taught to the students when they are observing how the teacher behave in the class and how they interact with other people in their group. Through hidden curriculum, teachers could teach moral value/principles to the students without taking out time from materials in the main curriculum.
