This paper aims to explore effective methods for integrating mathematics and biology through mathematical modeling and its impact on student learning. In this context, the study identifies strategies to enhance student engagement and interaction in the learning process. The study employs a descriptive and analytical approach, utilizing data collected from teachers' experiences and student learning outcomes to the effects of integrating mathematics and biology, as well as the influence of teachers' professional development on student learning. The findings indicate that the use of mathematical modeling as an educational approach can facilitate changes in teaching methods and increase learning opportunities for students. The modeling activities introduced in this paper have been implemented through professional development programs for teachers and incorporated into classroom settings. These activities help students develop analytical and problem-solving skills and enhance their motivation to explore the connections between mathematics and biology. The results of this study emphasize the importance of creating collaborative and interdisciplinary learning environments that utilize innovative educational methods to foster deeper and more effective learning in both domains. Additionally, the paper offers suggestions for improving teacher education and effectively integrating mathematical modeling into curricula.
