In this article, Michelle DeMeulenaere discusses social/emotional learning (SEL), with a focus on helping preschool children gain knowledge about feelings and getting along with others. SEL is the process in which children are able to acknowledge and recognize the emotions of others, develop empathy, make good decisions, establish friendships, and handle challenges and situations effectively. Early childhood teachers have a strong impact on guiding children's social and emotional development by creating a safe and supportive environment, focusing on the child's feelings, helping children develop language, and discussing the topics of how children develop SEL. The stability and security of the teacher-student relationship directly influences social and emotional learning. Effective teachers (1) encourage children to participate in classroom activities; (2) listen to what children say, and expand upon their language, building vocabulary and knowledge; and (3) plan activities that have a purpose and challenge the children. Teachers also encourage children to respect each other and their surroundings as the children observe adult emotions and behaviors exhibited with both students and peers.
