<![CDATA[Team-Based Learning (TBL) is an active learning method that can be used to enhance behaviors promoting adolescent reproductive health. This study aimed to determine the effectiveness of the Team-Based Learning method in improving the determinants of reproductive health-promoting behaviors among adolescents in Islamic boarding schools in the Aceh Besar Regency. A quasi-experimental design with a comparative quantitative approach was employed. The sample consisted of 110 female adolescents aged 15–19 years, evenly divided into intervention and control groups. The intervention group received four TBL sessions over two weeks, while the control group did not receive the TBL intervention during the study period. Data were collected using self-report questionnaires and analyzed using the Wilcoxon test via the R program. The results showed significant improvements (p<0.05) in the intervention group's scores following the TBL intervention across various factors: personal factors, perceived benefits, perceived barriers, self-efficacy, appreciation, interpersonal influences, situational influences, interest, commitment to a plan of action, individual strength, empowerment, participation, control, genital hygiene practices, management of menstrual issues, and detection of genital diseases. Thus, TBL proved effective in enhancing the determinants of reproductive health-promoting behaviors among adolescents in Islamic boarding schools and is recommended as a health education method for adolescents.]]>
