The application of social-emotional and character development (SECD) in classrooms is about teaching, practicing, and modeling essential personal and civic life habits and skills that are almost universally understood as making people good human beings. Among these habits are respect, responsibility, integrity, caring, fairness, and constructive problem solving. It is difficult to imagine how a classroom or a school can function unless children are well versed in these habits of thinking, feeling, and acting. SECD is a blend of two important traditions in education: social and emotional learning (SEL) and character and moral education (CE). Social-emotional learning and character and moral development are critical to student success. This article presents examples of SECD as it can be applied in classrooms or schools, and outlines eight ways to build social, emotional, and character development.
