This theoretical paper examines the role and significance of emotions in learning and teaching in the lower grades of elementary school. Research has shown that positive emotions have a desirable impact on students' well-being and, significantly for this paper, their learning and academic success. The importance of emotional development in the context of education is emphasized because there is often an excessive focus solely on students' cognitive development, neglecting their emotional and psychomotor abilities. Greater attention should be directed toward integrating emotions into the educational process to stimulate the development of students' emotional intelligence. Furthermore, emotions are frequently undervalued in schools, despite their pivotal role in all phases of learning and teaching. Positive emotions should prevail to achieve success, while negative emotions should be minimized. Negative emotions in school, such as stress and fear, are present on a daily basis, and teacher criticism can negatively affect students. Placing a greater emphasis on praise and support for students is important to balance the negative effects. Finally, the objectives of this work include explaining the importance of emotions in the educational process, defining the concept of emotions and emotional intelligence, considering emotional development in children, identifying factors influencing emotions and academic results, and exploring ways to encourage positive emotions in teaching. In summary, emotions play a crucial role in the learning process and should be an integrated part of the educational system to facilitate the comprehensive development of students. More attention should be given to emotional development to ensure better educational quality and improved academic achievements for students.
