Purpose: This review research paper aims to explore and understand the significance of emotional intelligence (EI) in relation to effective teaching and classroom management. It seeks to investigate how teachers' emotional intelligence impacts their instructional practices, student engagement, and overall classroom climate. The paper draws upon the framework of emotional intelligence, which encompasses the ability to perceive, understand, and regulate emotions, as well as to utilize emotions effectively. It also incorporates theories and concepts related to teaching effectiveness, such as teacher-student relationships, classroom management strategies, and student motivation. A comprehensive review of existing literature is conducted to examine the relationship between emotional intelligence and various aspects of effective teaching and classroom management. Both qualitative and quantitative studies are considered to provide a comprehensive analysis of the topic. The findings highlight the crucial role of emotional intelligence in fostering positive teacher-student relationships, enhancing instructional delivery, and promoting an optimal classroom environment. Teachers with higher emotional intelligence tend to create supportive and inclusive learning environments, effectively manage student behavior, and respond empathetically to students' emotional needs. The research findings have significant implications for teacher education programs, professional development initiatives, and school policies. By recognizing the importance of emotional intelligence, educational institutions can prioritize the development of emotional intelligence skills among teachers, leading to improved teaching practices and enhanced student outcomes. Moreover, the promotion of emotional intelligence in classrooms can contribute to students' social-emotional development and overall well-being. This review research paper consolidates and synthesizes existing literature on the role of emotional intelligence in effective teaching and classroom management. By integrating various perspectives, theories, and empirical evidence, it provides a comprehensive understanding of the topic. The paper's value lies in its ability to inform educators, administrators, and policymakers about the significance of emotional intelligence in educational settings.
