Educational applications and technology have been utilized to enhance children’s learning in recent years. Children are increasingly using tablets and smart devices for learning at home and in classrooms. Research indicates that Social-Emotional Learning in children is crucial for their interpersonal relationships and future success, as it enhances their emotional intelligence (Greenberg, 2023). Technology-based SEL can contribute to improvements in emotional skills, peer relations, and prosocial behaviors (Low et al., 2023). However, the effectiveness of using technology and applications has not been fully examined. This study is thus aimed to investigate the effectiveness of an Emotional Learning App in facilitating social-emotional learning in preschool-aged children, using data from the larger Empathy Learning Project, which focuses on emotional coaching in community preschools. The present interdisciplinary study began with a computer science student developing an app using Swift. The app is designed to teach social-emotional learning (SEL) to improve emotional skills. It includes features to help children learn to identify facial expressions and customize them by interchanging various facial parts, encouraging imaginative play, and enhancing social-emotional skills. The app is then used in a community preschool for children ages 3-5. Twenty-three children participated in the study. The accuracy of emotional recognition was first tested to establish a baseline (pre-test), and again followed by 2 months of SEL using the app and other methods. Teachers are asked to complete the Social Competence Behavior Checklist (SCBE, LaFreniere, 1998) before and after the SEL lessons. The data collection is underway. It is expected that using the app will promote emotional learning in children. Further details and implications of the app will be presented at the conference. These findings will contribute to the growing research on the importance of SEL in young children.
