Social and Emotional Learning (SEL) has emerged as a pivotal framework in modern education, promoting emotional intelligence, relationship building, and responsible decision-making among students. This paper takes the initiative to define SEL from various perspectives, discusses the core principles of SEL, and also explores the impact of SEL on classroom dynamics, academic performance, student behaviour, and teacher-student relationships. Evidence from multiple studies shows that SEL fosters a supportive learning environment, enhances student engagement, and improves overall academic outcomes. It also discusses various challenges faced during the implementation SEL in the classroom scenario. The article also has a review of the literature on similar findings. It concludes with suggestions as to how more effectiveness can be improved in the incorporation of SEL in the classrooms.
