A total of 30 female high school students from District 5 of Tehran were selected through convenience sampling and randomly assigned to experimental (n=15) and control (n=15) groups. The experimental group participated in a 10-session intervention involving STEM-based choice theory education, while the control group received no intervention. Self-efficacy and creativity were assessed using validated questionnaires before and after the intervention. Data were analyzed using multivariate covariance analysis (MANCOVA) to determine the intervention's impact.</p> <p><strong>Findings:</strong> The results indicated significant improvements in both self-efficacy and creativity in the experimental group compared to the control group. For self-efficacy, the intervention explained 89.7% of the variance (F(1, 24) = 208.425, p &lt; 0.001, η² = 0.897), while for creativity, it accounted for 93.1% of the variance (F(1, 24) = 324.466, p &lt; 0.001, η² = 0.931). These findings suggest that STEM-based choice theory education effectively fosters both self-belief and innovative thinking in students.</p> <p><strong>Conclusion:</strong> STEM-based choice theory education is a highly effective approach to enhancing self-efficacy and creativity among high school students. By addressing cognitive and emotional dimensions of learning, this intervention offers a robust framework for empowering students and preparing them for complex problem-solving and innovation. The results highlight the importance of integrating psychological theories and interdisciplinary education into school curricula to foster comprehensive student development.</p> https://www.maherpub.com/index.php/jndd/article/download/286/207
