<![CDATA[This research is motivated by the persistently low level of polite behavior in second-grade students at the UPT SDN 024 Tanah Merah. Politeness is an important character value instilled from an early age because it is related to students' daily behavior at school. Therefore, the role of teachers is crucial in developing polite and courteous character in students through various habituation efforts. This study aims to describe the role of teachers in developing polite and courteous character in second-grade students at UPT SDN 024 Tanah Merah. The research method used was a qualitative case study. Data collection techniques included observation, interviews, and documentation. Data were analyzed qualitatively through data reduction, data presentation, conclusion drawing, and verification. This study used triangulation to validate the data.The results indicate that efforts have been made to develop polite character in students through various habituation activities in the learning process and daily interactions at school, but implementation has not been fully optimal. Students' polite character is reflected through eight behavioral indicators: saying thank you, saying sorry, saying please, being friendly, not interrupting, expressing opinions politely, being humble and positive, and respecting the opinions of others. The teacher's role in shaping this character includes serving as a guide, enforcer of class rules, and facilitator, as well as role model, motivator, and instructor. However, in its implementation, several obstacles exist, namely teachers' inadequate understanding and insight, inconsistent teacher role models, and limited time and workload.]]>
