Special Issue on Public Policy: Front Matter

It is with great pleasure and honor that we introduce the Third Special Issue of the CODEE Journal with the theme, Engaging the World: Differential Equations Can Influence Public Policies.Here, we share different ways of making connections between mathematical modeling via differential equations and the practical realms of public policies.As educators, researchers, and enthusiasts of mathematics, we recognize the profound impact that differential equations play in shaping our understanding of complex systems and in turn, informing sound public policy decisions.The articles within this special issue span a spectrum of perspectives, from innovative teaching and course administration ideas to insightful investigations into the practical applications of differential equations to many real world applications such as epidemics, population dynamics, oligarchy and taxation, mandatory voting, groundwater flow, aircraft takeoff distance, and sustainability projects.Indeed, this special issue is a testament to the interconnectedness of classroom and research mathematics to societal well-being.We extend our sincerest gratitude to all our contributors and reviewers for their dedication in making this Third Special Issue a reality.They are all seasoned mathematics educators and emerging mathematics scholars from the USA, Lebanon, and Australia.May the insights that they share in this Special Issue inspire continued collaboration, dialogue, exploration, and innovation in the teaching and learning of differential equations.
