Investigating Proportional Reasoning from Two Perspectives

NSF Awards: 1420307

2017 (see original presentation & discussion)

Accomplishments include being able to generate sound explanations for notorious difficulty topics like fraction division and explaining how two quantities can co-vary in such a way that their measures form a fixed ratio..
