This paper highlights the critical role of the modeling-based teaching method in the instruction of the series chapter in Advanced Mathematics at Tra Vinh University. This method aids students in bridging theoretical knowledge with practical applications through visual models and mathematical tools such as graphs, equations, and series. In addition to explaining the fundamental concepts of mathematical modeling, the paper provides real-life application examples, such as calculating bank loan interest and predicting population growth. The study asserts that modeling not only enhances students’ logical thinking and problem-solving abilities but also improves learning outcomes through active learning approaches. This approach is deemed an essential solution for improving teaching quality amidst the modernization of education.This paper highlights the critical role of the modeling-based teaching method in the instruction of the series chapter in Advanced Mathematics at Tra Vinh University.
