The variables in this study consisted of the SEL approach as the independent variable (X) and student’ disciplined and polite character as the dependent variable (Y). Data were collected through observation, questionnaires, and documentation. The collected data were analyzed using descriptive statistics and the Pearson Product-Moment correlation test.The results showed that the implementation of the SEL approach at SDN 8 Telaga Biru was categorized as good, with a percentage of 72.00%.

The learning environment plays a critical supporting role in this relationship, as a safe, inclusive, and emotionally supportive classroom setting amplifies the effectiveness of SEL implementation.Therefore, it can be concluded that the SEL approach positively correlates with the formation of disciplined and polite character in elementary school students. A well-structured and conducive learning environment is essential to optimize the outcomes of SEL-based character education.
