This course comprehensively discusses the social-emotional development of early childhood (ECD) with a theoretical and practical approach. Students will learn the nature, characteristics, and stages of social-emotional development of ECD based on developmental theories from experts such as Erikson, Bowlby, and Goleman. The discussion includes factors that influence social-emotional development, both internal factors such as temperament and emotional intelligence, as well as external factors such as parenting patterns and the social environment. This course also equips students with the skills to design social-emotional stimulation programs that are integrated into the ECD curriculum, including development evaluation techniques using observation and documentation instruments. To strengthen students‘ understanding and skills, learning is carried out through various methods such as interactive lectures, case discussions, project-based learning in compiling development programs, and learning simulations through peer teaching. Students will have direct experience analyzing child development cases, designing stimulation activities according to age stages, and practicing social-emotional development assessments. Through this combination of theoretical and practical learning, students are expected to be able to understand the characteristics of social-emotional development of ECD, identify supporting and inhibiting factors for their development, and apply appropriate development strategies in early childhood education settings. Learning evaluation is carried out comprehensively through individual and group assignments, mid-term and final exams, and assessment of micro teaching practices.
