The promotion of social and emotional learning (SEL) in schools may help prevent emotional and behavioral problems of students. This study evaluated the effects of a SEL curriculum, Strong Start, on the social-emotional competence of 26 second grade students, using a quasiexperimental, non-equivalent control group design. Results revealed statistically significant and meaningful improvements in teacher ratings of students' internalizing and peerrelated pro-social behaviors, particularly for students at greater risk. Conversely, control group students experienced significant worsening of internalizing behaviors and decreased levels of peer-related pro-social behaviors. No changes were reported in externalizing behaviors for either group. Treatment integrity and social validity ratings of Strong Start were high. Limitations and implications of this study are addressed.
There has been increasing interest in the promotion of social and emotional learning in schools, and research has shown positive outcomes. However, relatively few studies have been conducted in kindergarten classrooms or considered the feasibility of kindergarten implementation. This study examined the effects of Strong Start on the social and emotional competence of 67 kindergarten students, using a time-series design. Four kindergarten teachers taught the ten Strong Start lessons in their classrooms. Results indicated gains in students' prosocial behaviors and decreases in internalizing behaviors, as rated by teachers and parents. Implementation integrity and teachers' ratings of social validity were high, suggesting the program's feasibility and potential effectiveness in natural classroom settings. Limitations and implications are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
