Proportional reasoning is a ubiquitous part of the humanexperience. We engage in proportional reasoning to meetboth informal and specialized goals across a range ofdomains, such as medicine (e.g., disease rates, drug dosages),finance and commerce (e.g., interest rates, discounts),cooking and baking (e.g., scaling ingredient amounts), andmany others. Given this variation in usage, it may not besurprising that proportional reasoning does not have asingular definition or interpretation, but instead is a complextopic with many interconnected concepts. The central goal ofthis symposium is to shed light on this complexity bydiscussing diverse perspectives of proportional reasoning.
