Toward a Unified Theory of Proportion

AbstractProportional reasoning is a ubiquitous part of the human experience. We engage in proportional reasoning to meet both informal and specialized goals across a range of domains, 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), and many others. Given this variation in usage, it may not be surprising that proportional reasoning does not have a singular definition or interpretation, but instead is a complex topic with many interconnected concepts. The central goal of this symposium is to shed light on this complexity by discussing diverse perspectives of proportional reasoning.
