Which of the following behaviors is inappropriate for adults working with children?

Chewing gum in front of children is considered inappropriate behavior for adults working with children because it can set a poor example and potentially distract from a positive learning environment. Children are keen observers and often mimic adult behaviors. If adults engage in behaviors such as chewing gum, it may normalize this behavior for children, which is generally deemed unprofessional in educational settings. Moreover, it can detract from the authority and seriousness of the adult's role as a caretaker or educator.

In contrast, options involving giving instructions calmly, offering praise and feedback, and modeling positive behavior are essential practices that foster a supportive and effective learning atmosphere. These behaviors encourage children's social, emotional, and cognitive development. Chewing gum, however, does not contribute positively to this environment and can be seen as disrespectful or careless in the eyes of children.
