Self-esteem is one of the key determinants of successful learning and the gaining of social skills and is fundamental to the general well-being of all students. Feeling competent, having a can-do attitude, feeling good about themselves, students are much more likely to actively engage in the learning process, which can only result in better learning outcomes. Low self-esteem plays a significant role in early school leaving. Improving the self-esteem of students at risk of early dropout has proven to be an effective preventive tool. There are several ways that teachers can support students with low self-esteem. Creating a supportive learning atmosphere, with differentiated instruction that is sensitive to individual needs, establishing realistic expectations and goals, allowing choices, and offering positive feedback focussing on strengths and abilities are all key factors in this process.
