To reinforce social behavior teachers should

a. choose one staff member to deal with unacceptable behaviors.
b. give children words to use in place of physical aggression.
c. try not to involve parents in “school rules.”
d. foster independence in children.

Choosing to reinforce behaviors sometimes mean adding a pleasurable consequence or a removing an unpleasant one – these are the basic building blocks of operant conditioning, a concept posited by B. F. Skinner.

By giving punishments to children who use physical aggression and giving appropriate reward for children who use words instead, the teacher would be able to change the children’s behaviors.
