We developed a pilot course focused on mathematical modeling within the tertiary education framework, with a distinct emphasis on sustainability and sustainable development. While an applicable textbook exists for this liberal arts course, it is noticeable that numerous examples within it are not directly aligned with sustainability concerns. To address this gap, our study strategically integrated the teaching and learning of modeling by carefully selecting classroom examples that closely align with the context of sustainability. By employing an innovative and adaptable approach to the course content delivery, we fostered interdisciplinary collaboration among students, improved their comprehension, and enhanced their interdisciplinary skills.
