Interest in emotional, social, and moral (ESM) concerns in K-12 education in North America has grown considerably during the past decade. This increased concern is considered a response to the increased prevalence of social problems experienced by children and youth, such as bullying, substance abuse, and depression, and to research indicating that schools can influence the likelihood of students having these types of problems (Schonert-Reichl 2000). Research and theory in psychology which suggests that emotional development is an essential foundation of cognitive development and, therefore, is related to academic achievement also has contributed to this expanded interest (Martin and Reigeluth 1999). A variety of names, including affective education, social and emotional learning, values education, character education, caring education, and moral education, have been used in discussing ESM. Despite the prevalent use of these terms in the literature, the school programs that actually have been implemented under these various auspices are discussed rarely. Further, little, if any, research has explored the relative effectiveness of various approaches. Through a review of the literature, this article provides an overview of the history of ESM education in North America. It also outlines the spectrum of contemporary approaches to ESM education and explores the similarities and differences of these approaches, making suggestions for further theoretical and empirical work.
