The evolving horizons of mathematical modelling in education reveal its transformative potential to bridge disciplines, inspire innovation, and address complex societal challenges. This volume highlights the significance of collaboration in advancing mathematical modelling, emphasizing partnerships among students, teachers, researchers, and industry professionals. Such collaborations enrich classroom practices, enhance integration, and foster interdisciplinary connections. The chapters in this book explore five key areas of mathematical modelling education: integrated approaches; societal, cultural, and historical perspectives; teacher education; student engagement; and the role of digital resources. Together, these perspectives demonstrate the potential of mathematical modelling to equip learners with the knowledge and critical capabilities to navigate the challenges of modern societies. By documenting current and future thinking about collaborative and innovative practices, this book aims to redefine the global horizons of mathematical modelling education.
