Model the social skills you want your preschoolers to emulate. Children are constantly imitating the adults in their lives. Both teachers and parents need to teach by example.
Discuss emotions with your preschoolers and practice different facial expressions that coincide with different emotions. Children who have the proper vocabulary to express what they are feeling are less likely to act out.
Encourage dramatic play either by participating or prompting your students. Toy kitchens, dress-up clothes, dolls and action figures are all toys that promote dramatic play. This allows you to observe what your preschoolers consider to be normal behavior.
Observe your preschoolers' interactions. Whether in the classroom or on the playground, you need to be mindful of how your preschoolers are interacting with their peers.
Allow children to solve their own problems whenever possible, but be prepared to intervene if conflicts continue.
Discuss incidents as soon as they occur. For example, a preschooler may say something hurtful without realizing it. By immediately explaining why his words were hurtful, you decrease the chances of a similar incident in the future.
